New QHY MiniCAM8 astro camera - all in one imaging system

Earl White.Jan 08, 2025
One of the more exciting releases for astrophotographers is the the new QHY miniCAM8 system. It's a handy way to add a compact imaging setup to an existing rig and a perfect step up for those start to get serious about their astro photos.  It's an affordable and easy to use way to add to a mono or colour astro imaging camera to your telescope along with: A built-in filter wheel Commonly used filters customised for the miniCAM8 Integrated cooling system  Powerful camera 512 MB of DDR3 RAM to handle data transfer of even large images 1.25" and 2" nosepiece adaptors This combination is a small but powerful astronomy camera for both deep-sky imaging, an eight position filter wheel in about the same form fact you'd normally find a five position filter wheel taking up. There's also built-in electronic cooling for dropping the temperature of the imaging system by around 45C. This helps reduce electronic noise for much sharper and clearer images.  The camera itself is the IMX585 sensor, well known for its exceptional sensitivity which means its well suited to even challenging conditions and tricky targets. The system also features anti-dew control and zero amplifier glow  The miniCAM8 is available in two variants, a one-shot colour camera with four filters included. These have been customised by Optolong Optics. They are: Light pollution filter Heavy light pollution filter Four-channel enhancement filter UV/IR cut filter The custom filters included with the colour version of the QHY miniCAM8 The mono version both LRGB and SHO narrowband filters for deepsky imaging, all designed by XiMei Filters. The filters included with the mono version of the QHY miniCAM8 Both the colour and mono filter sets are19 mm x 12 mm * 1.1 mm in size which makes them a perfect match the for the miniCAM8 camera and filter wheel. The QHY miniCAM8 is supported by wide range of software such as N.I.N.A and SharpCap We're expecting both models of the QHY miniCAM8 Imaging Systems to become available next month and for a limited time we're offering free shipping to all parts of Australia. Check them out via these links: QHY miniCAM8 Colour Camera - Deepsky Combo QHY miniCAM8 Mono Camera - Deepsky Combo You can also secure one with  25% deposit.

A new comet? Comet C/2024 G3 (ATLAS) is on the way...maybe

Earl White.Jan 06, 2025
1
UPDATE: 13th January - Movie of C/2024 G3 (ATLAS) looping around the Sun as it passes through Perihelion. Seems intact and no major signs of breakup or disintegration. Things are looking good for a decent show in the early evening Australian skies later this week. Image via SOHO, the Solar & Heliospheric Observatory. More here. ---------------------------------------------------------------------------------- A Comet with the very poetic name of C/2024 G3 (ATLAS) is about to have a close encounter with the Sun and if it survives  - and this is a very big "if" - could be one of the most spectacular astronomy events of 2025.  When was this Comet discovered and why do so many comets now seem to have "ATLAS" in their names? It was found on the 5th of April 2024 by the automated Asteroid Terrestrial-impact Last Alert System (ATLAS) system. This is an asteroid impact early warning system that scans the entire sky every night looking for moving objects that could pose a threat to us folks here on Earth. It's one of several early warning systems against incoming hunks of space rocks. You can read more about the ATLAS program here. As a result of scanning the sky so regularly and comparing it from night to night, the ATLAS program often finds comets when they are a long way from the Sun and appear as stars, giving away their true nature by the movement against the background of Milky Way stars.  Why the big "if"? Comet C/2024 G3 (ATLAS) is a sungrazing comet. Detailed observations revealed it to be a long period comet, meaning it's not a new arrival from the Oort cloud. It's visited the inner Solar System before. It will make its closet approach to the Sun, called perihelion, on January 13th, where it will be well within the distance that Mercury orbits the Sun at some 13.5 million km from our nearest star. The very closeness of this approach to the Sun is what makes C/2024 G3 (ATLAS) an exciting object to track and follow.  Comets are often referred to as "dirty snowballs", meaning they're loose clumps of water ice, frozen gases and other materials from the early stages of the Solar System. As they loop around the Sun during their orbit, some of this material is heated up and thrown into space. A thin atmosphere surrounding the comet expands into space where it can be seen as a fuzzy ball.  Material thrown away from the comet becomes the tail and shines either because of direct reflection of light from the Sun (a comet's dust tail) or because some of their gases are excited by the Sun's energy and emit their own light (the ion tail). It's not uncommon for comets to appear to have more than one tail, sometimes spreading at different angles to the comet itself. Even though comets themselves are usually only a few dozen km in size, their brightly illuminated tails can stretch out over millions of kms, sometimes even being larger than the Sun itself.  The behaviour of even regular cometary visitors to the inner Solar System can be hard to predict. Just how much material is thrown into space and how that will behave is an educated guess. It's even harder to say with certainty exactly how sungrazer comets will behave. As they travel close to the Sun, larger amounts of these comets are ejected into space and more likely to make a big splash in the sky.  Some of the most spectacular comets ever seen were sungrazer comets, such as Comet Lovejoy in 2011 and the even brighter Comet Ikeya–Seki in 1965.The downside of skirting so close to the Sun is that comets can be completely torn apart by this journey and then drift off into space. We had high hopes for C/2024 S1 (ATLAS) last year, however it was demolished by the Sun. Read more about sungrazers here. Sungrazing Comet Ikeya–Seki- in 1965 near Kitt Peak Observatory.  Image via  Roger Lynds/NOIRLab/NSF/AURA/ – taken on Kodak Ektachrome We'll know shortly after C/2024 G3 (ATLAS) passes close to the Sun on January 13th whether it has survived somewhat intact and will be then visible in the coming weeks.  What could I see and when can I this comet? (Assuming it scoots through ok...)  It's estimated the comet will become visible in the evening sky in Australia from around the 16th or 17th of January, where it will be heading away from the Sun.   UPDATED: The spot in the sky where Comet Atlas (C/2024 G3) should be visible on the evening of the 20th January 2025 around 8.30pm. It will appear a little higher in the sky each evening and still be visible as the evening darkens, although it will also rapidly fade.  It should appear as a bright spot with a tail fanning out away from the comet. Full Moon is on 14th January 2025 in Australia, so the Moon will be below the horizon when the comet is visible early in the evening and won't interfere with viewing.  When will we know whether Comet C/2024 G3 (ATLAS) has it made around the Sun intact? Given the potential for this comet, there will be a lot of interest about its behaviour after perihelion. We'll be keeping a close eye on any observations and sources like the Astronomer's Telegram and others for the latest news. I'll update this article as soon as we know more.  What do I need to view this comet? Our general advice with bright comets is to use binoculars. These give a nice wide field of view and are ideal for seeing the finer details of a comet's tail, especially if it's large and spread over several degrees. A telescope will give a close up views of a comet's coma, but won't be able to fit the tail into the field of view if it's spread over a larger part of the sky. Nikon Aculon 10x42 binos at BINTEL - more info here.  They don't need to be fancy either. Try the ones you have at home or look at the Nikon Aculon range here at BINTEL. These are affordable (starting at well under $200) and offer sharp clear view of the night sky and are ideal for day time viewing of birds, nature and sports.  I've read this is the best comet of 2025. Why are folks saying this? There are no periodic comets due to appear in skies for the rest of the year that will be bright enough to be seen with just your eyes, so yes, C/2024 G3 (ATLAS) could be the best comet of 2025. However, comets have a habit of surprising us and with any luck, the next Great Comet might dazzle us later in the year. I'll be updating this article with more charts as more info becomes available.  Cheers, Earl White BINTEL  6th January 2025

January 2025 - The planets align - UPDATED!

Earl White.Jan 03, 2025

January 20th 2025 - Update: it's not just the 25th of January - no need to rush! We've had quite a few folks contact us up about this planetary alignment, how to see it and when it will be visible. Some were worried that they should travel someone on the night in case it was cloudy where they lived or were planning work or social events around it!  Please remember that while many websites and social media postings are saying the date is the 25th of January for this event, as mentioned below, planetary alignments like this event are slow moving and there's no need to rush. Venus, Saturn, Mars and Jupiter will visible in the sky on that night and for quite a few afterwards. No rush - plenty of planets to go around! It's visible in sky NOW and will be for some time after the 25th of January.  As an added bonus, if you have a clear view to the west, this week you should be able to see Comet C/2024 G3 (ATLAS) not too from Venus. More here ----------------------------------------------------------------------- Have a look towards the western and northern skies this month and you'll see a line of fellow members of our Solar System strung across the horizon in the early evening sky. This is simply an alignment of planets as seen from the ground here on Earth and they haven't moved towards each other in any significant way. Moving from left to right, you'll see Venus and Saturn close together when it gets dark. This will be the last chance to see Saturn before it emerges in a pre-dawn sky in a few months. By then, its rings will be even more edge on and harder to see. (We'll be talking a little bit more about that later in.) Jupiter is higher in the sky and will be visible for much of the night. Apart from the Moon, it will be the bright thing in the evening once Venus sets and looks like the lighting on a incoming airliner flight - except you'll notice after a while it's not moving.  Mars will also be rising and is coming into the best time to view the red planet until its next opposition in 2027. You'll notice in the chart that the outer ice giant, the planet Uranus, is listed. This won't be visible to you eyes, although you should be able to see it in pair of binoculars. The other ice giant, Neptune, appears close to Venus and would be quite difficult to spot.  Mercury is lost in the Sun's glare and would be below the horizon as it starts to get dark.    Do I need a telescope to view these planets? Not really. You should be able to see all of these bright planets with you eyes and they'll all be bright compared to the background stars. However, once you spot them, they'd be well worth checking out with in binoculars and telescopes of any size will show more.  Is there a certain time or day I need to view this line up? This is generated by Stellarium for the 25th of January 2025 around 9.15pm local time. If you'd like to generate your own chart for your location, visit their site here. However it will be visible in the days before and after this date, so no rush. Cheers,Earl White  BINTEL 3rd January 2025

The BINTEL 2024 Wrap Up

Earl White.Dec 31, 2024
2024 was a very special year for BINTEL First of all, we celebrated 40 years since the shop first opened in 1984 in the Wynyard Station arcade. It’s been an amazing journey and can only thank our customers, suppliers and the many others who’ve helped us get this far. The BINTEL Sydney store 40 years ago 2024 also saw the roll out of new products continue, and along with a few long term favourites, made this year a stand out for how we could help our customers expand their interests in astronomy, bird watching, nature discovery and more. Here’s BINTEL’s “wrap” for 2024* Smart Telescopes We’ve written a lot about Smart Telescopes over the last few years, and with good reason. These all-in-one telescope, mount, camera and control systems are changing with the way astronomers of all levels of expertise view and photograph the night sky. There were three major Smart Telescope updates during 2024 and all of them are worth a mention here.Celestron Origin Intelligent Home ObservatoryThis new telescope was released by Celestron at CES (Consumer Electronics Show) in Las Vegas in January of this year. It’s a high end smart telescope and the result of years of R&D by Celestron. Definitely a long term project from the world's largest telescope manufacturer. Celestron Origin We’ve now sold dozens of these Celestron Origin gizmos, with excellent feedback from our customers along the way. I know my eyes glaze over whenever something is described as a “game changer”, but this new Celestron Smart Telescope is exactly that. Find out more here.There’s been several sub-$1000 Smart Telescopes available to astronomy enthusiasts for the last couple of years. The popular DWARF II morphed into the new DWARF 3, which is a major hardware and software upgrade for around the same price while ZWO introduced their new Seestar S30 which is selling for only just $649. ZWO Seestar S30 Smart Telescope  We were also impressed that ZWO met their promised mid to late December delivery target for this new little Smart Telescope and we were able to dispatch some to our customers before the end of 2024. The DWARF 3 Smart Telescope What 2025 will bring in terms of Smart Telescopes is looking exciting. I’d say that the few years has probably seen more astro photos taken with these new telescopes than were taken in the last two decades with more traditional astrophotography rigs. Binoculars ZEISS were the stand out binoculars at BINTEL for 2024. Their ZEISS Terra ED line up are well priced for those after an introduction to quality binoculars without the high price tags and this has seen many become ZEISS owners over the last 12 months. ZEISS Terra ED 8x42 BinocularsFor more serious birdwatchers, the ZEISS SFL binos have been a revelation. Bright and crisp images combined with lightweight bodies make a perfect combo when you’re out in the field. ZEISS SFL 8x40 Binoculars 2024 also saw the release of the new ZEISS Conquest HDX binoculars. Mid-priced with a new optics and weather proofing have made them popular with those after a genuine all-around set of optics. ZEISS HDX 10x42 Binoculars The Kite Optics APC Stabilized 14x50 ED lifted the bar for image stabilised binos. A combination of new image stabilising tech, large ED (Extra Dispersion) quality glass and built-in Lithium-Ion battery that will last an entire season make these Kite binos a must have for long range viewing. Kite ED 18x50 Image Stabilised Worth a big mention too has been Gerber binoculars. These are possibly some of the best value products we have at BINTEL. Great views for the money! 2024 - Year of the spotting scope? We’ve always been a destination for anyone with a decent view they’d like to see up close. This year we seem to have had a stream of people calling and visiting us who are living near the water or with scenery to explore. The BINTEL spotting scope range - small telescopes optimised for going beyond what binoculars can achieve - has been expanding this year. Apart from evergreen offering from Celestron, Nikon and Swarovski, we’ve welcomed new spotting scopes from Kowa, ZEISS and Pentax to our shop. The KOWA TSN-88 Spotting Scope   Best optics of the year? I’m a bit torn on this one! Two remarkable spotting scopes arrived at BINTEL this year. The KOWA TSN-88 with its crystal fluorite lens has jewel-like optics and the carbon fibre BORG 90FL is the Swiss army knife of small telescopes that lets you configure it for anything from birdwatching to astro imaging. BORG 90FL Telescope Set CR (Carbon Tube) Telescope Mounts New and upgraded Harmonic Drive mounts continue to arrive at BINTEL. One that impressed us is the updated ZWO AM5N mount. This added to the popular AM5 mount a swag of new features and capabilities as bumping up the load capacity. ZWO AM5N Harmonic Drive Mount Dobs are back! (Actually, they never went away….) While electronic telescopes of various kinds grab a lot of attention, there’s nothing like the simple joy of observing the night sky with your eyes through a decent sized telescope. We’ve seen plenty of new telescope owners opting for the handy Celestron StarSense Explorer tabletop Dobsonians this year. The saxon full-sized Dobsonian telescopes were especially popular for Christmas, and we expect this to continue into 2025. saxon 8" Dobsonian Telescope  Books Astronomy 2025 is the last edition of our favourite star gazing annual. This has been a standard resource that has informed and entertained astronomers in Australia and across the world since the early 1990s. While the 2025 production is the final edition from the team at Quasar Publishing, it's no doubt one of their best effort. Everyone here at BINTEL would like Quasar for the wonderful publication that's served our community over the decades. Events The total Solar Eclipse that crossed the USA on the 8th of April 2024 saw a vast number of people travel to the eclipse's path to experience this rare display of our nearest star, the Sun.  The April 2024 Solar Eclipse as seen from Texas, USA. It was also a timely reminder that there will a Total Solar Eclipse in Australia in July 2028 - and it will cross directly over BINTEL in Sydney!SpaceX launched its BIG rocket. The largest rocket ever built, Starship, flew a number of times in 2024, with the next flight due in January 2025. Each flight saw the reliability and capabilities increase with each launch including the "chopsticks" capture of the main booster.  Starship 5 launch from the SpaceX facility Locally, Gilmour Space received the go ahead for the first permit for an orbital launch from the Australian mainland from their facility in northern Queensland.  Other highlight space missions were the launch of the Europa Clipper to explorer the suitability of one of Jupiter's large moons and the close encounter of the Parker Solar Probe as dived close to the Sun over Christmas. The NASA spacecraft survived and first results are due in the coming days. Happy New Year! Cheers, Earl White BINTEL *2024 Wrap? Sounds like a plan. I wonder if anyone else does that?

Summer Solstice 2024 - the longest day of the year

Earl White.Dec 21, 2024
Happy Summer Solstice - Why is the Sun  One of the delights of summer in Australia is enjoying the longer days as the Sun sets later and later.  The reason why the days vary in length throughout the year is because our Earth orbits the Sun at an approx. 23 degree angle. This causes the Sun to spend more time in the southern part of the sky during our warmer seasons and less time during the colder months.  On the Summer Solstice, the Sun reaches the furthest south in the sky and begins its journey into the northern part of the sky. It also marks the longest day of the year.  This year the Summer Solstice is the 21st of December 2024. (It can change a day from this date from year to year.) From then on, the days begin to get shorter, until we reach the shortest day of the year, the Winter Solstice. The Autumn Equinox in March is when all parts of the Earth experience the same amount of day and night time. How long your day will be in major capital. Image via weatherzone.  While the days begin to shorten in length from this coming weekend, the time the Sun sets gets a little later until early January. Don't worry - those long and lazy summer evenings will continue for a while yet.  For this coming summer, the Sun will set just after 8.00pm during January while starting to rise a bit later.  For example, in Sydney the sun will set around 8.09pm local time while the time it rises changes from 5.47am as 5.45am the days begin to get shorter post Solstice.  You can read more about the rise and set times at this website here. (Please note that times given do not include daylight savings. You'll need to add an hour if your location uses it.) Path of the Sun in the sky.  As we orbit the Sun during year, where the Sun appears in the sky changes each day.   Image via César Cantú / AstroColors If you were to take a photo of the Sun at the same clock time every day over a course of the year from the same location it would produce the same same every year. The roughly figure-8 pattern the Sun traces out is called an Analemma. This Analemma is a result of our orbit around the Sun and the tilt of the Earth.  For this Summer Solstice, the Sun's image would be as far south as it gets for the year. Cheers, Earl White BINTEL

Jupiter at its best for 2024 - check it out now!

Earl White.Dec 07, 2024
The largest planet in the Solar System as close as it will come to Earth in 2024 right now and it's the perfect time to view and photograph Jupiter.  During closer approaches when the Earth and Jupiter are the same side of the Sun (called "opposition") it's the 3rd brightest object in the night sky behind the Moon and Venus.  Jupiter has been known by peoples from all parts of the world since ancient times.  Viewing Jupiter With your eyes alone: Jupiter shines as very bright star not far the constellation of Orion this summer and is inline with Betelgeuse, the deep-red star that forms one of the "shoulders".  Where Jupiter can be found this weekend (7th and 8th of December 2024) around 10.30pm local time You won't be able to see any details on Jupiter nor will you be able to see any of the four largest moons*.  Where the Sun, Earth and Jupiter are aligned during this year's opposition. Illustration via NASA Binoculars: With just about any pair of binoculars Jupiter will start to be no longer be a single point of light but start to have a definite circular shape. There's a very good chance you'll also spot as many as four small "stars" spread out either side of Jupiter.  These are the planet's largest four moons, first definitively recorded by Galileo in January 1609 and independently a day later by astronomer Simon Marius. Marius didn't write about his discovery for time afterwards. While we refer these collectively as Jupiter's Galilean moons, we use the names for them proposed by Marius: Callisto Europa Ganymede Io Each of these moons is a world in itself, with complex geological processes and even oceans. NASA's Europa Clipper mission launched some weeks ago to investigate the suitability of Europa as a place for life.  Telescopes: Even a small telescope will start to reveal the darker bands and lighter streaks that run across the surface of Jupiter. What you're looking at are icy cold regions of ammonia and water floating on the planet's atmosphere of hydrogen and helium. With telescopes of 150mm aperture or larger you'll even see a vast storm, larger than the Earth, called the Great Red Spot. As Jupiter rotates every 10 hours, the position of the Great Red Spot will change throughout the night or might even disappear as it heads behind the planet and out of view.  Eyepiece upgrades: Solar System planets like Jupiter are ideal astro objects for using higher magnifications. Many telescopes are supplied with a 25mm for wide field views and a 10mm for higher magnification.  We can help with suggested individual eyepieces to suit you telescope. Another option is to buy a Barlow. This sits between your telescope and the eyepiece and effectively decreases the focal length of the eyepiece, which means it increases the telescope's magnification. For example, this $49 Celestron T-Adapter-Barlow Lens 1.25 inch would double the power of each eyepiece. Find out more here. While Barlow lenses are not a perfect solution, they offer an affordable way to increase the range of your telescope.  Motorised telescopes and taking photos:  Any telescope with a computerised and motorised tracking mount will make extended visual observing of planets much easier and open up options for taking detailed photos of them as well. Solar System planets were some of the astro objects that amateur astronomers turned their early digital cameras to a few years ago and they quickly produced images that were far superior to even the best film cameras of the time.  The reason fairly low-cost planetary cameras can produce such planetary photos is because of a technique called lucky imaging. It you look at the stars at night you'll night they "twinkle". This shimmering of these points of light in the sky is caused by minor disturbances in the quality of the atmosphere. Wind currents, patches of warmer and colder air and other factors means amount of twinkle, or "seeing" as astronomers call it, varies from not just night to nigh but throughout the evening and sometimes even moment to moment. If you look through a telescope at a telescope at a planet like Jupiter, it might appear to wobble around or be blurry. Then suddenly, the view will be razor sharp for a while and then go back to being a big dodgy.  A planetary camera attached to a tracking telescope like this Celestron NexStar 4SE doesn't take a single image like you would with your phone. Rather, it takes a video and using software to examine the quality of each frame and then combine the clearer and sharper views captured and discard the less than ideal frames. It then combines them into a single image - with often amazing results. Celestron NexStar 4SE - more details here. ZWO ASI678MC Colour Planetary Camera- more details here Whether you're looking Jupiter with just your eyes, a binocular or telescope or even planning to photograph the gas giant, think about the complex and expansive world above our heads tonight.  Cheers, Earl White BINTEL 5th December 2024 *Yes, there are some folks who claim to be able to see these moons with their eyes along and without binoculars or a telescope. They are just on the outer edge of human visual capabilities under near perfect conditions, so grab a pair of binos or a small telescope and enjoy them.

Binoculars for under $300 and under $700 for Christmas 2024

Earl White.Dec 06, 2024
It's not long until Christmas and binoculars are always popular gifts for exploring nature, enjoying summer and for close up views at sports or event concerts. Here's some of our suggestions for 2024 Under $300 The Nikon Aculon Range of Binoculars We're super happy that Nikon have kept their Action EX Binoculars affordable for those after viewing quality and rugged construction. These feature the usual Nikon quality multi-coated optics with, with waterproof o-rings and filled with nitrogen. This will prevent the from fogging up internally even under damp and less than ideal conditions.  They would be handy companions for: Bird Watching Nature Viewing Whale and dolphin watching Camping and hiking Sports and concerts Around the water and boating Night sky and astronomy Discover Nikon EX Binoculars at BINTEL here. For example, the Nikon Action EX 10x50 is a full sized pair of binoculars that would be suited for longer distance viewing and especially handy for taking out on the boat this summer. You can find more details here. Under $700 The ZEISS Terra ED line up offers ultra crisp and clear optics in a more compact body style. We've had a big 12 months with ZEISS here at BINTEL and received some positive feedback from our customers about their binoculars, especially birdwatchers and those travelling to demanding locations such as Antarctic islands or even on safari.   Read more about ZEISS Terra ED Binoculars here. Some of the ZEISS Terra ED Binoculars available from BINTEL These would be a step up in terms of image quality compared to the Nikon Action binos mentioned above, and definitely more compact.  Ideal for: Bird Watching Nature Viewing Whale and dolphin watching Camping and hiking Sports and concerts Travelling, both local and overseas Night sky and astronomy ZEISS Terra ED binoculars include a semi-rigid case for additional protection. One suggestion would be the ZEISS Terra ED 8x42. This is perhaps the classic size for birdwatchers especially and would offer years of service in the field. You can read more our these binoculars here. What's the best size binoculars?  There's no one set size you should use for any particular activity. In other words, despite what you might read online there's no one size that all the bird watchers use or one size for whale watching etc.  There's two factors to consider. Binoculars are described like this: 8x25 10x42 7x50  And so on. The first number is the magnification or how much the binoculars increase the size of the image as you see it. While it might see the highest number is always the best option - after all, the point of binoculars is to increase the size of things in the distance, isn't it? - but higher magnification also means a narrower field of view when searching for fast moving things like birds or sports action as well a emphasising and hand movements or shakes.  The second number is the diameter of each front lens in mm. For example,  10x32 and 10x42 binoculars would both produce the same size image to your eyes but the 10x42 binoculars would gather more light due to the larger lenses. This would make them better for low light conditions or for use during dawn or dusk as well as producing a slightly sharper image. They'd also be heavier and likely more expensive.  Here's a few suggestions for sizes and their uses. This a rough guide and have a chat with us to fine tune the right model binoculars just for you: Bird Watching - 8x42 or 10x42 for more experienced birders Scenery viewing from land - 10x50 or 10x42 Whale Watching on the water - 10x42 Sports - 7x50 or 10x50 Concerts - 10x32 Travelling - 8x32 Compact/pocket sized - 8x25 These are only a rough guide and we're always more than happy to chat about specific binocular models and sizes to get one that's just right for you.  Cheers, Earl White BINTEL 5th December 2024

这是智能望远镜领域令人惊奇的一年。当我在近 18 个月前撰写 2023 年 BINTEL 智能望远镜指南时,我们就知道它们会越来越受欢迎,但即使是 BINTEL 的工作人员也对新技术以及涌向这些令人兴奋的设备的各种各样的新手和经验丰富的天文学家和自然爱好者感到兴奋。 首先,简单回顾一下——智能望远镜到底是什么? 我们通常认为智能望远镜是集望远镜本身、完全计算机化的“GOTO”支架、摄像头以及管理图像捕获和处理所需的相关技术于一体的一体化装置。 它们还可以通过手机、平板电脑或 iPad 上运行的 Android 或 Apple iOS 应用程序通过 Wi-Fi 进行控制。 这款应用程序负责在夜空中对准望远镜,通过了解望远镜在地球表面的位置并快速扫描天空来获取其位置。 完成后,您可以选择要查看或拍摄的内容。去年,这主要是通过从智能望远镜应用程序的数据库中选择一个天文物体来完成的,但到 2024 年,我们还将看到综合星图的进一步整合,让您可以探索和拍摄我们头顶上更广泛的夜空。 除了一些专用设备外,您无法“通过”智能望远镜进行查看。它拍摄的照片将显示在您的设备屏幕上。(稍后将提供更多信息……) ZWO Seestar S50 在我们发布的 2023 年智能望远镜指南中,ZWO Seestar S50 刚刚在美国 NEAF 展会上发布。几个月后它开始发货。从那时起,它们就成为了一个全球性的成功案例,我们在 BINTEL 这里销售了大量产品。例如,我们曾多次在一天内向客户运送了 100 多台小型 Seestar S50。 如果您只对天文摄影感兴趣,ZWO Seestar S50 可能是您经济实惠的智能望远镜的最佳选择。它配有坚固的泡沫手提箱、桌面三脚架、内部滤镜和外部太阳照片,用于拍摄太阳及其太阳黑子的照片。 虽然已经推出 18 个月了,但 ZWO 已经通过应用程序更新为 Seestar S50 提供了多项升级,并且还有更多升级即将推出。例如,“马赛克”功能目前正在测试中。这可让您从更大的天空区域拍摄多张图像,并将它们组合成一张图像。 矮人实验室 我们 DWARF Lab 的朋友们在过去的 12 个月里一直很忙! 他们生产并销售了非常受欢迎的 DWARF II 智能望远镜。这款望远镜比 ZWO Seestar S50 更小巧,更便于携带,虽然它无法像 S50 那样拍摄出精细的图像,但可以拍摄更广阔的视野。它也深受鸟类观察者和自然摄影师的喜爱。 刚刚开始发售的新型 DWARF 3 带来了一系列新功能。 DWARF 3(左)与 DWARF II(右)的对比——体积稍大,但威力更大 DWARF 3 的整体尺寸没有大幅增加,但主镜头尺寸从 24 毫米增加到 35 毫米,与 DWARF II 相比,望远镜的聚光能力提高了一倍多。相机也进行了重大升级,采用索尼 IMX678 传感器,电池性能更好,等等。 DWARF 3 还进行了重大软件更新并增加了新功能,包括在 EQ 模式下延长曝光时间、图像马赛克和改进的自动物体跟踪 - 适用于拍摄鸟类、飞机、流星甚至一两个奇怪的不明飞行物......您现在还可以使用广角相机拍摄天文照片,结合马赛克模式,DWARF 3 可以成为传统 DSRL 和星跟踪器拍摄银河系方法的经济实惠且功能强大的替代方案。 升级 DWARF 3 的最大优点可能是价格与 DWARF II 基本相同。我们很少看到制造商将型号光学元件的直径增加 40%,升级即将推出的型号的几乎所有功能,同时保持价格不变的望远镜。 ZWO Seestar S50 还是 DWARF 3? 现在这个问题更难回答了。如果你只对天文成像感兴趣,那么稍大一些的 ZWO Seestar S50 在近距离拍摄和拍摄更详细的图像方面仍然比 DWARF 3 更有优势。马赛克功能的出现将削弱 DWARF 3 更宽视野的优势。然而,DWARF 3 的广角相机上增加了天文功能,可以拍摄更大的全景照片,这可能会让你感兴趣。此外,即使是稍大一些的 DWARF 3 也比 ZWO Seestar S50 小得多,这可能是便携性和旅行的一个因素。 如果您不确定或只是想提出一些想法,请致电 BINTEL。我们非常乐意详细讨论这两款入门级智能望远镜。 无论如何,没有其他方法可以以不到 900 美元的价格获得这两台很酷的小设备所能拍摄的深空天文照片。 更新:2024 年 10 月 1 日 - ZWO Seestar S30 正如我在本文结尾处提到的,智能望远镜制造商将推出新产品,这里就有一款新产品 - ZWO Seestar S30。 它比原来的 ZWO Seestar S50 更小、更便携。 ZWO Seestar S30 即将登陆 BINTEL 目前,我们还没有完整的详细信息和规格。Seestar S30 即将发布,预订将于 2024 年 11 月 1 日开始。如您所见,它比已经很紧凑的 Seestar S50 小得多。 ZWO Seestar S30 即将登陆 BINTEL 我们认为 ZWO Seestar S30 会吸引那些想要一款便于携带且功能齐全的智能望远镜的人。更多内容即将推出! Vespera II 和 Vespera Pro 法国公司 Vaonis 生产了第一批智能望远镜之一 Stellina,随后于 2023 年又推出了最初的 Vaonis Vespera。 这款设备比 ZWO Seestar S50 更大,风格独特,光学和电子性能明显更好。Vaonis 应用程序和用户界面比现有产品更强大、更易于使用。 2024 年,Vaonis 将 Vespera 升级为 Vespera 2,并推出了新款 Vespera Pro 型号。 Vaonis Vespera 2024 年阵容 摄像头是 2024 年 Vespera 型号升级的重要组成部分。与原版 Vespera 相比,Vespera II 的百万像素大小增加了四倍,而新款 Vespera Pro 在此基础上又增加了 50%。这使得可生成的图像大小大幅增加。 这也大大降低了分辨率或采样率,从而可以拍摄出更精细的图像细节。Vespera Pro 可以捕捉小至 1.6 角秒的图像细节。 虽然各种马赛克或图像拼接功能版本即将出现在售价低于 1000 美元的智能望远镜上,但 Vaonis CovalENS 多成像系统已经成熟且功能齐全。这允许您精确地构图您想要拍摄的区域并实时观看大型全景图。例如,使用 CovalENS 的 Vespera II 可以拍摄超过六个满月宽度的夜空区域。 更新:2024 年 10 月 2 日- CovelENS 升级。Vaonis 发布了有关该软件重大更新的信息。天文摄影师对如何制作具有复杂细节的暗淡物体图像很感兴趣,新的多夜观察模式就是其中之一。这可以让您在晚上关闭成像会话,并在第二天或更晚的晚上无缝地重新开始拍摄物体。他们的马赛克图像合成系统和功能也进行了重大更新,以计划您在成像会话期间拍摄的内容。更多信息请访问 Vaonis 网站。 除了功能更强大的摄像头外,与 Vespera II 相比,Vespera Pro 的额外功能还包括更大的内部存储空间、更长的电池寿命、全套 Vaonis 配件甚至还有防盗系统。 Vespera 智能望远镜与低成本选项相比有哪些优势? 主要优势在于,两种 Vespera 型号拍摄的图像质量明显高于 DWARF 或 Seestar S50。Vespera 更大更重,但仍然非常便携且易于安装,尤其是在黑暗中。Vaonis 应用程序 Singularity 可让初学者轻松拍摄天文照片,同时为经验丰富的人提供高级功能。最后,Vespera 是一款优雅的设备,我们有不少用户甚至将其作为家居装饰的一部分。 Celestron 也加入了这场派对。Origin 智能家居天文台 目前的智能望远镜供应商均没有实际制造任何类型望远镜的经验 - 除 Celestron 外。 总部位于加利福尼亚州的 Celestron 几十年来一直是世界上最大的望远镜和相关设备供应商。他们还长期为业余天文学家推出计算机化的支架和望远镜。他们的第一款智能望远镜 Celestron Origin 于 2024 年 1 月在拉斯维加斯的 CES(消费电子展)上发布,并立即成为功能最强大、功能最齐全的智能望远镜,这并不令人意外。 与所有其他现有智能望远镜不同,Celestron Origin 在某种程度上是模块化的,基于 Celestron 多年来在其他型号中不断完善的多项技术。例如,望远镜本身是一种称为 RASA 的反射镜。它具有极快的 f/2.2 焦比,可提供极宽的视野,与其他设备相比,可以在更短的时间内捕捉深空细节。 Celestron Origin 的口径为 150 毫米(6 英寸),比其他智能望远镜大得多,这意味着它能够对较暗的目标进行成像,并生成较亮天体的更精细细节。与其他只能通过软件升级的智能望远镜不同,Celestron Origin 的一些硬件可以通过硬件更新和附加组件进行改进。Celestron 表示,相机升级以及楔形物和自动导向器正在计划中,以实现更准确和更长的曝光。 除了是目前最昂贵的智能望远镜之外,Celestron Origin 还更大,并且设置和运输与传统的天文摄影设置类似。 有什么东西是无法用智能望远镜拍摄的吗? 是的。它们的焦距都相对较短。这使得它们非常适合深空天体,例如星团、星云,甚至是我们银河系以外的星系。太阳系行星在天空中占据的空间很小,通常需要长焦距望远镜才能观看或捕捉它们。 智能望远镜是否会取代更传统的天文摄影平台? 简短的回答是否定的,但事实并非如此。 我们不知道有哪位对天文摄影非常热衷的客户现在使用智能望远镜代替他们现有的天文成像设备,因为它们能拍出更好的天文照片。智能望远镜的照片不如最好的传统望远镜、天文相机和支架以及相当多的经验拍出的照片好。事实上,我认为这种情况还需要很长时间才能发生。 过去几年来,我们使用过各种类型的智能望远镜,其中很大一部分最终落入了刚刚开始接触天文学的新手手中,但也有很大一部分是由经验丰富的天文学家购买的,他们想要一个可以轻松生成清晰图像的天文系统,并且易于设置,使用起来很有趣。 智能望远镜拍摄的图像还能进一步改善吗? 是的。 所有智能望远镜收集的数据都经过软件处理,以显示尽可能多的细节。它们的应用程序可以产生一些相当惊人的结果,现在所有型号都允许您下载“原始”数据,以便在您的设备上进行处理,甚至可以使用 Siril 或 PixInsight 等外部程序。 最后——近期会有新型号推出吗?我应该现在购买智能望远镜还是等待? 当然,未来还会有新型号和新功能出现。智能望远镜是望远镜制造商的成功之作,但他们需要跟上步伐。他们面临着来自现有供应商甚至新兴厂商的新产品。与其他“热门”技术领域一样,他们的工程师和设计师正在努力开发下一代产品。 如果你说“我会等待接下来发生的一切”,那么你可能会推迟很长时间才开始你的天文之旅。当然,未来会有新的装备推出,但目前这一代的智能望远镜是有史以来最简单、最有效的认真研究天文学和开始探索宇宙的方法。 对于最经验丰富的天文学家来说,身边发生这样的事情确实是一件奇妙的事情。 干杯, 厄尔·怀特 宾特尔 2024 年 9 月 18 日
