• A complete digiscoping solution: NexYZ connects your smartphone to almost any eyepiece
• NexYZ’s patented design works with telescopes (with most 1.25” or 2” eyepieces), spotting scopes, binoculars, monoculars, and microscopes (with the included adapter rings).
• Works with virtually all smartphone models, including the latest devices from Apple, Samsung, and Google.
• Features three directional knobs (X-, Y-, and Z-axis) that perfectly align your phone’s camera with the eyepiece in seconds. In addition, you can make tension adjustments to keep the phone firmly in place.
• Stands up to rigorous field use thanks to its robust, durable construction with a metal frame and polymer body.

The NexYZ 3-Axis Universal Smartphone Adapter is a great first step into the world of astroimaging or digiscoping. The NexYZ provides you everything you need to capture sharp, detailed images and video.

Patented NexYZ Smartphone Adapter

NexYZ fits any eyepiece from 35mm to 60mm in diameter, including telescopes equipped with 1.25” or 2” eyepieces, spotting scopes, monoculars, and binoculars. It also attaches to microscopes with the addition of an included adapter ring, which takes the usable diameter down to 25mm, the size of a standard microscope eyepiece.

NexYZ accommodates a wide range of smartphones including the larger “phablets” like the iPhone 11 Plus and latest Samsung Galaxy devices. The phone platform is fully adjustable and can fit any device—usually with the case still on. The secure platform stands up to the weight of these heavier devices with ease, thanks to NexYZ’s strong metal spring and threaded twist lock. Should you need to tighten the tension on each axis for a customized secure connection, click the Support & Downloads tab to read our NexYZ Tension Adjustment Guide.

Easy as X-Y-Z

What makes NexYZ’s patented design different from other smartphone adapters? The three-axis adjustment. Most adapters rely on you placing your phone perfectly on the platform and only offer limited adjustment in two axes. But NexYZ gives you the power to place your phone on the platform, center it over the eyepiece with the X and Y knobs, and then move up or down over the eyepiece until you have the entire field of view in your shot.

And even though this adjustment is ultra-precise, it’s still quicker and easier to use than other adapters. From start to finish, the process only takes about 30 seconds, including the time it takes to insert the phone into NexYZ, attach NexYZ to an eyepiece, start the camera app, and center the camera over the eyepiece using the knobs.

Switching phones, eyepieces, or optical instruments, requires only slight adjustments to re-center the camera over the new eyepiece. If multiple people want to capture a shot through your optic, NexYZ’s simple spring-loaded clamps make it easy to remove one device and replace it with another in seconds. NexYZ is the ideal solution for star parties and group bird walks where everyone wants their own shot of the action.

You can also switch your image from portrait to landscape simply by turning the padded eyepiece clamp and readjusting the X-, Y-, and Z-axis to realign your phone with the eyepiece.

NOTE: NexYZ is compatible with telescopes, spotting scopes, binoculars, monoculars, and microscopes. It does not fit riflescopes. NexYZ works with most phone cases, but if you have an especially large phone case with built-in batteries or a folio-style case, you will need to remove it.

Praise for NexYZ

“Unlike other adapters, the NexYZ features three directional knobs (X, Y and Z axes) that perfectly align your phone’s camera with the scope eyepiece in seconds. In addition, you can make tension adjustments to keep the phone firmly in place and, rather pleasingly, the clamp system allows the phone to be positioned to capture images in landscape mode as opposed to portrait, which is so often the hallmark of most smartphone images.” – from Expert Reviews, Birdwatch magazine, November 2018

“Fitting the phone to the adapter is simple and quick, and the phone is held securely in place – no need to worry about it dropping out as you move around. You then adjust the phone’s position using the X and Y axis knobs – this too is easy and relatively quick. Finally, the Z axis knob enables you to lower or raise the phone to eliminate vignetting.” – Matt Merritt, “Unlock your phone’s potential,” Gear Reviews, Birdwatching magazine, August 2018

Solar Warning

• Never look directly at the Sun with the naked eye or with an optic (unless you have the proper solar filter). Permanent and irreversible eye damage may result.
• Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it.
• Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.

The Celestron 1.25” Eyepiece and Filter Kit is a great way to expand the functionality and enjoyment of your telescope. Inside the metal, foam-lined carry case you’ll find these accessories:

• 32 mm Plossl Eyepiece - 1.25”
• 17 mm Plossl Eyepiece - 1.25”
• 13 mm Plossl Eyepiece - 1.25”
• 8 mm Plossl Eyepiece - 1.25”
• 6 mm Plossl Eyepiece - 1.25”
• 2X Barlow Lens - 1.25”
• #80A Blue Filter - 1.25”
• #58A Green Filter - 1.25”
• #56 Light Green Filter - 1.25”
• #25 Red Filter - 1.25”
• #21 Orange Filter - 1.25”
• #12 Yellow Filter - 1.25”
• Moon Filter - 1.25”

Eyepieces - All five Plossl eyepieces can be used in any telescope with a 1.25” focuser. Each eyepiece features a four-element design with a 52º apparent field of view. The optics are fully multi-coated to improve light transmission and protect the optics. The 32 mm Plossl eyepiece offers a low power, wide field view in most telescopes, the 13 mm & 17 mm focal lengths are good medium-power oculars, and the 8 mm & 6 mm eyepieces provide high magnifications, great for the Moon and planets, especially when seeing conditions are good.

2X Barlow Lens - The included, and very versatile 2X Barlow doubles the magnification of any 1.25” eyepiece. Since this kit includes five (5) eyepieces, you will be able to use them with and without the Barlow, giving you a total of ten magnification options in all. Any other 1.25” eyepieces you already have will also work in this desirable accessory, giving you even more magnification choices. Remember, high magnifications do not always produce clear, sharp results, especially on evenings of poor or moderate seeing conditions. Experiment to find the magnifications that are best for your telescope on a particular night.

Filters - Colored filters can be used to bring out certain details on a planet’s surface or its cloud structure. All of the planetary filters included in the 1.25” Eyepiece & Accessory Kit, as well as the Moon filter, can be used on any 1.25” eyepiece with the proper filter threads, so they are very versatile. Just screw one onto your eyepiece of choice and slide it into the focuser.

The Moon filter is one of the first accessories most new amateur astronomers buy, and for good reason! It helps block out a portion of the light the Moon sends into your eyepiece so that you can see details better. You can also try this filter on Venus; it blocks enough glare so you can observe the planet’s phases more easily.

Metal Case: The sturdy metal carry case has die-cut foam inside to protect and cushion your accessories. Store each one in its appointed place when not in use and you’ll keep them looking and performing like new. The case is even large enough to carry a few extra accessories. Just pull out enough of the foam cubes to make a nest for your eyepiece, camera adapter, etc. A tight fit is better, so remove the least amount of foam possible before testing the fit. You can always remove more if you need to.

Celestron Moon Filter

The Moon has the distinction of being the most often viewed celestial object through backyard telescopes. It is undoubtedly beautiful and mysterious, and is one of those constants in our lives that connects us to every other being on our planet. Regardless of who we are or where we live or travel, we all look at the same moon.

It is difficult to look at the Moon through a telescope and see all of the details due to its brightness. Our eyes are not ready for the bright beam of light that emits from the eyepiece, and they “stop down”, just as they would when you step out into the sunlight on a bright summer’s day. When we’re in the sunlight, we often wear sunglasses. They help us relax our eyes, protect us from glare, and help us see things more clearly. When amateur astronomers observe the Moon, we use a moon filter. A Celestron Moon Filter provides similar benefits to those of sunglasses...our eye relaxes and opens up to let us see more detail. This is especially important when observing the Moon when it is near full.

The Celestron Moon Filter simply screws onto the insert barrel of most 1.25” eyepieces. It only takes a second or two to transform your regular eyepiece into one suited for lunar observations. A Moon Filter is also helpful when observing Venus or bright terrestrial scenes. This filter is not suitable for viewing the Sun.

Remove the lens from your camera and attach the T-ring in its place. Since the T-ring is camera-brand specific, it will snap right on just like a lens. Next, remove the diagonal and visual back from the rear cell of your telescope. Screw the Celestron T-Adapter onto the rear cell threads until secure. Now, thread the T-ring & camera onto the T-Adapter. That’s all there is to it. The camera is now using your telescope as a giant telephoto lens. The magnification will depend on the telescope’s focal length. For instance, a 300 mm camera lens is considered to be pretty powerful, right? Well, if you are using an 8” SCT at prime focus, you’ve got yourself a 2000 mm lens with a lot of light-gathering capability!

Prime focus photography is popular for short exposure images of terrestrial objects as well as celestial objects like the Moon. If you want to do longer exposures of deep sky objects with this method, we suggest using a separate guidescope or off-axis guider and an equatorial mount.

Spend less time centering your target and more time stargazing with the new premium Celestron StarPointer Pro finderscope. Traditional red dot finderscopes were originally created for shooting sports such as airsoft guns and shooting sports. StarPointer Pro was designed for astronomers by astronomers to provide the easiest experience locating celestial objects in the night sky. Whether you’re new to the hobby or a seasoned amateur astronomer, you’ll appreciate StarPointer Pro’s thoughtful design features.

While a red dot can obstruct your desired target, the Celestron StarPointer Pro projects two circular LED reticles. Just place your target inside the circles and it’s ready to view in the eyepiece. The circles also serve as a measuring tool while starhopping. For added convenience, StarPointer Pro offers a 40 mm optical window with a large field of view. StarPointer Pro attaches quickly to any telescope and secures with a dovetail connection and finger knobs. No screwdriver needed! Get more out of every stargazing session with StarPointer Pro.

Celestron Night Vision Red LED Torch

A red flashlight is one of the most beneficial accessories you can own as an amateur astronomer, no matter how occasional your night sky observations may be. Also, if you plan to observe with other people, whether at a star party or in your own neighborhood, a red flashlight is an important part of good star party etiquette.

When you are outside doing astronomy, or any night-time activity that requires you to see as well as possible, any white light is a detriment. Every time you use white light, your eyes react. The pupils contract, making their aperture smaller, and a smaller aperture always means less light-gathering, whether we are talking about your eyes or your optical equipment.

A red flashlight allows you to see your star charts, find an eyepiece in your accessory case, or pick your way over telescope cables and other obstacles without affecting your night vision. The better your night vision, the more you can see in the eyepiece.

The Celestron Night Vision Flashlight uses two LED’s to provide variable red illumination. Use the thumb wheel to adjust the light as you need it. The square shape of the flashlight keeps it from rolling off of your observing table to the ground. A lanyard is attached so you can wear it around your neck. The Night Vision Flashlight is powered by a 9V battery (included).

The Celestron T-Adapter-Barlow Lens Universal - 1.25'' can be used three ways; as a 2X Barlow for visual use, as a prime focus T-adapter, or as a “Barlowed” T-adapter to double the magnification.

Features:

1. As a 2X Barlow right out of the box. Insert any 1.25” eyepiece into the adapter to double the magnification, while retaining a comfortable eye relief of your eyepiece.
2. For prime focus photography. Unscrew the bottom section (glass element) to remove the Barlow and slide the chrome barrel into the telescope’s 1.25” focuser. Screw a T-Ring to the T Thread on top of the adapter. Attach to your DSLR or SLR camera.
3. As a barlowed T-adapter simply screw your T-Ring (sold separately) directly to the T-Thread and place into focuser. Good for imaging Planets to enlarge image.

Please note that some telescopes, especially “fast” refractors and Newtonians, may not have enough focus travel to allow the photographic image to come to focus when used in prime focus mode. In these instances, adding the Barlow to the T-Adapter will allow the telescope to reach focus.

In “Tele-Extended” mode, the Barlow doubles the focal length and f/ratio of your telescope, resulting in an image on the sensor or film plane that is twice the size of a prime focus image.

Prime focus and tele-extended photography are popular for short exposure images of terrestrial objects as well as celestial objects like the Moon.

Celestron NexStar 4SE Telescope Specifications

For more information, visit the Celestron website.

The self-alignment technology behind Celestron's award-winning SkyProdigy series is now available for all their current computerized telescopes, and backwards compatible with many older models as well (see compatibility list below). A small digital camera takes the place of your finderscope and attaches using one of two provided mounting brackets. The included StarSense hand control takes the place of your NexStar hand control. The camera automatically captures a series of images of the sky. StarSense identifies the stars in the images, matching them to its database. Once a positive match is confirmed, it calculates the coordinates of the centre of the captured image, thereby determining exactly where the telescope is pointed.

Before this technology, using a computerized telescope required a lengthy alignment process of finding and centering at least two bright stars in the telescope’s eyepiece. But StarSense automatically aligns itself with minimal user input. Just enter your time, date, and location, and let StarSense do the rest! Watch the video below for more information.

The hobby of amateur astronomy frequently takes the observer away from sources of AC power. After all, we are always in pursuit of the darkest skies possible, and that often means getting away from the city lights and going bush. The most common way to power your telescope in these situations is to use a commonly available, portable 12V battery pack or to use power from your car’s battery via the cigarette lighter.

The Celestron Car Battery Adapter is the accessory required for connecting any Celestron computerized telescope to a DC power supply or car battery. Plug the round post into the 12V input jack on the drive base of your telescope*, and insert the power connector into the cigarette lighter outlet in your car or on your power supply. The cord is 7.5m long, giving you plenty of reach between your telescope and 12V power source.

The barrel connector can be used with any telescope that uses a receptacle with an outside diameter of 5.5mm and an inner diameter of 2.1mm and a “tip positive” polarity.

*For use with the following telescopes:

• NexStar SLT Series
• NexStar GT Series
• CGEM Series
• CPC Series
• CPC Deluxe Series
• Advanced VX Series

A T-Ring is one of the first accessories you will need if you want to take pictures through a telescope or spotting scope. If you have a Canon EOS camera body, the Celestron EOS T-Ring is the one for you.

To use the Canon EOS T-Ring, remove the lens from your camera, and attach the T-Ring in its place, just as you would if you were mounting a lens. The telescope side of the T-Ring has threads that will accept a variety of camera adapters, including the Celestron T-Adapter or Tele-Extender. The adapter you choose depends on the type of photography you wish to do.

You can take pictures of terrestrial and/or celestial scenes by using a simple T-Adapter to turn your telescope or spotting scope into a large telephoto lens. The #93633-A T-Adapter is the best choice if you own a Schmidt-Cassegrain telescope with standard rear cell threads. If you have a refractor or spotting scope, the Universal T-Adapter (#93625), with its 1.25” barrel insert, is probably the best choice. There are also special T-Adapters for the EdgeHD optical system: one for the 8-inch EdgeHD (#93644) and one for the 9.25, 11, and 14-inch EdgeHD (#93646).

Prime focus photography is popular for short exposure images of terrestrial objects as well as celestial objects like the Moon.

If you need extra magnification beyond that which your Schmidt-Cassegrain telescope provides, a Tele-Extender (#93643) will allow you to insert an eyepiece inside the barrel before attaching it to the telescope. A Tele-Extender is used most often for high power images of the Moon and the planets.

The Tele Vue 2x Barlow provides double the magnification when used with any 1.25" eyepiece in your collection. For more magnification check out the Tele Vue 3x Barlow.

The chart below shows the effective magnification when spacing is introduced between the Barlow lens and image plane of your camera or eyepiece

Properly designed Barlows do wonderful things: They amplify power, slow the telescope's f/# (improving eyepiece sharpness), and give designers the opportunity to compensate for eyepiece aberrations.

Tele Vue Barlows use multi-coated high index glasses for optimum aberration correction, exceptional contrast with virtually no light loss. Observed performance is aberration free, even when tested with f/4 scopes. They even improve our competitor's eyepieces and telescopes!

Compromise image quality in any part of the optical chain and you've compromised every part! Tele Vue product design and execution deliver consummate satisfaction. Every Tele Vue Barlow must pass the same rigorous f/4, full field testing as all our eyepieces.

All Tele Vue Barlows now use brass clamp rings for secure, non marring holding of eyepieces and accessories.

Offered in 2x and 3x magnifications, these 1¼" Barlows perform identically. Simply choose either or both based on your eyepiece collection. Features include parfocal-ization, 1¼" filter threads, captive lock screws that won't fall out and full multicoatings.

ZWO 1.25″ IR UV CUT filter is suitable for colour camera with AR protect window.

The ZWO IR Cut Filter 1.25 blocks infrared light from reaching the sensor of your CCD or CMOS camera or your expensive H-alpha filter. When imaging, the addition of this simple and inexpensive accessory will result in sharper images, and when doing solar work, the IR Cut Filter will your protect H-alpha filter from the damaging effects of infrared radiation.

Infrared or IR light is invisible to the human eye, and so even though most telescopes are not designed to focus IR light, it does not matter when you are using your telescope visually. However, when you add a camera to the mix, its a whole other story! Unlike the human eye, a silicon sensor is very sensitive to light in the infrared portion of the spectrum, and that is a problem because infrared images are blurry as all get out. That means your nice, sharp visual light image is degraded by the addition of the infrared layer. This problem can easily be solved by blocking the infrared, and the ZWO IR Cu filter 1.25 will do just that.

The ZWO IR Cut filter is housed in a 1.25” cell, and has internal threads so that you can stack filters together. The filter comes with a protective plastic case.

The Celestron Cheshire Collimation Eyepiece is ideal for precise collimation of Newtonians and helpful for aligning Schmidt-Cassegrains. This special eyepiece fits into 1¼" focusers or diagonals.

Alignment is easy using the small opening on one end and thin cross hairs at the other end. The collimation eyepiece is more accurate than the simple Collimation Tool.

Product Description

ASI294MC Pro

The ASI294 is the first camera in the world equipped with the latest Sony sensor IMX294CJK.

DDR Memory Buffer

The ASI294MC Pro camera includes a 256MB DDR3 memory buffer to help improve data transfer reliability. Additionally, the use of a memory buffer minimizes amp-glow, which is caused by the slow transfer speeds when the camera is used with a USB 2.0 port.

DDR memory buffer is the main difference between ASI “Cool” and “Pro” cameras.

14bit ADC w/ 13 stops DR

The ASI294 has a 14bit ADC unit, allowing it to achieve 13 stops of dynamic range. This is an excellent characteristic for deep sky imaging, which is inherently high dynamic range. At 13 stops, the ASI294 has even more dynamic range than the ASI1600.

HCG Mode

HCG (high conversion gain) mode, which reduces read noise to even lower levels at higher gain without loss to dynamic range, is automatically enabled when the gain setting is 120 or higher. Read noise will drop under 2e-, while dynamic range will remain at 13 stops.

Full well Capacity

63700e full well, which is 3 times than ASI1600’s capacity. Even bright stars won’t saturate under long exposure.

This camera can achieve higher SNR(signal to noise ratio) with just one single exposure.

Reliable Mechanics

ASI294MC Pro has same mechanics as ASI1600 Pro. There are four screws that seal the sensor chamber. Our camera design has been extensively tested and is very stable.

Even when used in higher humidity environments, ASI294MC Pro will still work fine without dew problems.

High QE

The IMX294 sensor is a BSI (backside illuminated type) sensor, which has very high QE (quantum efficiency, which we estimate is over 75% peak).

Dark Current

The dark current of the ASI294 is slightly higher than the ASI1600, based on our test results.

Dark frame sample @ Highest dynamic range settings, 300s, -10°C, bin1. Please check the dark frame to make sure you fully know the performance.

ASI294MC Pro Dark Frame

USB 3.0 Port & USB2.0 HUB

USB 3.0 Port: Provide 5Gb bandwidth to make it possible for ASI294 Pro to run at 16 fps (14bit, normal mode) or 19 fps (10bit, high speed mode) at full resolution(11.7Mega).

Recommended cooler power supply: 12V @ 3-5A (or more) DC adapter (2.1×5.5mm, center pole positive). Also suitable: DC battery with 9-15V. Buy the power supply from Bintel too!

Using a battery 9-15V is also suitable for the cooler power supply.

USB 2.0 HUB: can connect with various accessories, such as filter wheel, guide camera and electronic focuser, so you can better manage your cables. The ASI294 Pro includes two short 0.5m USB 2.0 cables. The integrated USB 2.0 hub is powered by the external power source if you connect one.

Cooling System

The ASI294 Pro has a 2-stage TEC cooling system that enables deep cooling (35°C-40°C below ambient). The cooler requires an external power supply, which is not included with the camera. You may order a suitable power supply from Bintel here.

Celestron MAK T-Adapter NexStar 4SE

This sturdy aluminum T-Adapter is the accessory of choice if you’d like to attach an SLR or DSLR camera to the smaller rear cell threads of a Celestron NexStar 4SE telescope or C90 spotting scope for prime focus photography.

To get started, you’ll need the appropriate T-Ring for your camera body. Remove the lens from your camera and attach the T-ring in its place. Since the T-ring is camera-brand specific, it will snap right on just like a lens. Next, remove any accessories from the rear cell of your telescope.

Screw the Celestron NexStar 4SE T-Adapter onto the rear cell threads until secure. Now, thread the T-ring & camera onto the T-Adapter. That’s all there is to it. The camera is now using your telescope as a telephoto lens.

Prime focus photography is popular for short exposure images of terrestrial objects as well as celestial objects like the Moon.

A piggyback bracket is a simple astronomical accessory that can help you produce stunning photographs of the night sky. It allows you to attach a DSLR camera and lens to any Celestron SCT optical tube assembly and take advantage of the fact that your telescope has a dual-axis motor drive. When your telescope is running with the camera attached, you can take longer exposures without star trails, and capture details in objects that would have been impossible had your camera been attached to a photographic tripod or a telescope without a drive system.
