Description

Astronomer by night, astronomer by day! Observe the closest star to Earth during the day with the Vespera solar filter. The filter allows you to observe sunspots (dark spots) that show the intensity of the Sun’s activity.

Photograph the Sun with Vespera
The Solar Pointing mode allows you to observe the Sun in almost real-time using the live display*. Capture photos at any time from the Observation tab of the Singularity mobile app.

Take several shots at different times of the day, week or month and compare your photos. Witness how the Sun’s activity changes with the appearance or disappearance of sunspots. These can have a life span of several days, more rarely several weeks.

Observe safely
The filter is made of a metalized foil with a dimming effect. It will reduce the amount of light and allow you to observe the Sun in a way that is safe for your instrument. You will be guided through every step of your adventure by the Solar Pointing mode of the Vaonis Singularity app, to ensure the observation runs smoothly and that you and your instrument are safe.

Learn more in the Vaonis blog article Observing the solar activity with Vespera.

Warnings

• Your Vespera station should never be pointed towards the sun unless a solar filter is installed.
• You can only use Vespera to observe the sun using the Solar Pointing feature of the Singularity app and the solar filter specially designed by Vaonis. The use of any other means to observe the Sun (pointing by coordinates, pointing by hand, use of any other filter, etc.) would void your warranty in the event of damage to your equipment.
• Never look directly at the sun without adequate protection. Direct observation of the sun without protection and without a solar filter, even for a short time, can lead to serious eye burns and potential loss of vision or even blindness.
• Do not attempt to open the lens ring that contains the filter

ASI585MC Pro is a new ZWO deep sky camera based on the 4k SONY CMOS sensor with a 1/1.2″ format and 2.9μm pixels. It has a super high sensitivity and a large resolution of 3840*2160 (8.29MP in total). It also features high transmission speeds – In high-speed mode, the fast frame rate can reach 47fps at full resolution! Being an entry-level DSO camera, it offers great advantages of high cost-effectiveness.

Note:

External power supplies are needed for all ASl-cooled cameras. We recommend you use a 12V@3A~5A DC adapter (D5.5×2.1mm, center pole positive) or a lithium battery with 11-14V to power the camera. You can also use ASIAlR to power the cameras. Be aware that using a power supply out of this voltage range will probably lead to irreparable damage to the camera.

One Camera for All

The STARVIS 2 technology brings ASI585MC Pro more advanced imaging performance compared to other cooled cameras. Its high frame rate makes it not only suitable for DSO photography but also solar/lunar/planetary photography.

Moon -Christopher Schementi

NGC3372 ( eta Carina) -Simon Lewis

M42, NGC 1976 (Great Orion Nebula) -Simon Lewis

STARVIS 2

STARVIS 2 was developed by SONY and evolved from STARVIS. It is the latest technology with a wider dynamic range and super-high sensitivity beyond the human eye. Benefiting from it, ASI585MC Pro’s sensitivity and signal-to-noise ratio is greatly improved.

Large Full Well Capacity

The back-illuminated structure improves the camera’s full well capacity. Even with unbinned 2.9μm pixels, ASI585MC Pro has a full well capacity of 40ke-, nearly 3 times that of the last-generation sensor IMX485. A larger full well capacity gets the camera higher efficiency in collecting light, can effectively restrain the highlight area from being overexposed, and also can improve the signal-to-noise ratio.

Zero Amp Glow

ASI585MC Pro exhibits extremely clean dark frames with zero amp glow! No matter how long the exposure and how high the gain value is, you can easily get clean and smooth astro images!

Note: This feature is implemented directly at the hardware level, it does not require software control.

512MB DDR3

ASI585MC Pro uses a USB 3.0 interface, along with the built-in 512MB DDR3 cache, ensuring high-speed, smooth, and stable data transmission.

USB 3.0 Port & USB 2.0 HUB

USB 3.0 Port: Provides 5Gb bandwidth to allow ASI585MC Pro to run at 47fps at 8.29MP full resolution (10bit, high-speed mode).
USB 2.0 HUB: Can be used to connect various kinds of USB devices such as EFW, guide camera, and EAF.

Two-stage TEC Cooling

Thanks to the two-stage TEC cooling, ASI585MC Pro can lower the CMOS sensor temperature to more than 35 degrees Celsius below ambient temperature, which can greatly reduce dark current generation and sensor noise even during extended exposure times.

*The Delta T 35℃ is tested at 30℃ ambient temperature. It might get down when the cooling system is working for a long time. Also, as the ambient temperature falls, the Delta T would decrease.

Below is the dark current curve of ASI585MC Pro at the temperature from -20℃ to 30℃.

Camera Performance

Low read noise, High dynamic range

The camera has a built-in HCG mode, which can effectively reduce read noise at high gain and allow the camera to maintain the same high dynamic range as it does at low gain.

When the gain reaches 252, the HCG mode will be automatically turned on and the dynamic range reaches a level close to 11bit. The read noise in this case can be as low as 0.9e.

QE (Quantum efficiency)

Based on our testing results, the QE peak value of ASI585MC Pro is 91%.

Star Analyser 200

Since its launch in 2005, the Star Analyser 100 has introduced thousands of amateur astronomers worldwide to the fascinating field of spectroscopy. Over this period, the equipment used by amateurs has evolved with larger aperture telescopes, bigger camera sensors and close coupled filter wheels becoming more common. The Star Analyser 200 model has been developed with these users in mind.

Using the same Paton Hawksley high efficiency blazed diffraction grating technology as the SA100, but with double the line density. The SA200 is designed for applications where it is difficult to achieve the optimum spacing needed for the SA100. The SA200 gives the same length of spectrum at half the spacing compared with the SA100.

KENDRICK SUN FINDER: For use with filters and telescopes without a built-in solar finder
Makes locating the sun and centering it in your eyepiece a cinch! The Kendrick Sun finder projects a solar dot onto the white target which can be viewed either from the front of the finder or through the cut out on the back.

The finder comes with a double-sided adhesive foam tape to easy adhesion to a solar filter ring or another surface.

Can be mounted on any telescope

Warning:

Never look directly at the sun without correct filters.

Permanent eye damage can happen

The Celestron PowerSeeker Accessory Kit is a great way to expand the enjoyment of your telescope. Inside the plastic, foam-lined carry case you’ll find these accessories:

• 15mm Kellner Eyepiece - 1.25”
• 9mm Kellner Eyepiece - 1.25”
• #80A Blue Filter - 1.25”
• #25 Red Filter - 1.25”
• Moon Filter - 1.25”
• Microfiber Cleaning Cloth

Eyepieces - The 15mm and 9mm eyepieces can be used in any telescope with a 1.25” focuser. Each eyepiece is fully coated to improve light transmission and protect the optics. The 15mm Kellner eyepiece offers a nice medium magnification view in most telescopes, and the 9mm provides high magnifications, great for the Moon and planets, especially when seeing conditions are good.

Filters - Coloured filters can be used to bring out certain details on a planet’s surface or its cloud structure. Both planetary filters, 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 #80A is a medium-blue filter that enhances the contrast of the cloud belts on Jupiter and the polar ice caps on Saturn. It also can be used to increase contrast on the Moon if you don’t mind the color shift.
• The #25 filter is a deep red color and is a good choice when you want to define the polar ice caps on Mars. It’s also fun to use this filter when observing Jupiter. The #25 Red filter blocks quite a bit of light coming through your telescope, however, so it is best used on bright objects with larger aperture telescopes.
• 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 helps you see which phase she’s in.

Cleaning Cloth & Case - Keep the microfiber cleaning cloth stashed in your PowerSeeker Accessory Kit case so that it will always be handy. It’s better to use a microfiber cloth on your optics than wipes or tissue, as it will not leave a residue, and can be reused. Remember to blow or brush any dust particles off of your optics before rubbing them with the cloth.

The black plastic carry case has die-cut foam inside to protect and cushion your accessories. Keep each one in its appointed place when not in use and you’ll keep them looking and performing like new.

Wind, an unsteady tripod, or even an accidental bump can disturb your image quality. Keep your telescope still while observing with these sturdy pads. Simply place your tripod legs on top of the pads to absorb shock and stabilize your telescope.

Celestron’s set of three Vibration Suppression Pads are manufactured using Sorbothane ® (available only in the USA) recognized worldwide as the ultimate material for attenuating shock, isolating vibration and damping noise. No synthetic rubber or polymer can dissipate energy as effectively.

• 3 vibration suppression pads go under your tripod legs to stabilize your telescope and prevent unwanted shaking
• Made with Sorbothane" only available in the USA. Cheap imitations use silicon which do not absorb shock and may melt in the Sun.
• Engineered by Celestron specifically to dampen vibrations
• Works on any surface

The highest optical precision and the hydrophobic multicoating guarantee brilliant images down to the very last detail. The Terra ED binoculars are waterproof and nitrogen-filled, making them rough and ready. Terra ED binoculars are excellent value for money, making them the perfect entry into the world of ZEISS.

A bright image, outstanding resolution of details and comfortable viewing characteristics. In combination with optimum ease of handling, these perfectly describe the outstanding properties of the Terra ED 42.

High quality, fast refractors have a lot going for them when it comes to astrophotography but they come with a downside - field curvature. This is where the image comes to sharp focus on a curved surface. The problem is that the sensors in cameras are flat. The larger the sensor - like those used in cameras with APS-C sized or larger sensors or DSLR cameras - the more effect is noticed.

A field flattener brings the image to focus on a flat surface, like your camera's sensor. At the same time, the basic optical performance of your telescope remains the same.

You will need 55mm of backfocus.

The Bintel T-thread Spacer Ring Kit (sold separately) is recommended to achieve proper distance for use with CMOS imagers.

Use with a DSLR only requires a T-ring for the camera (T-ring sold separately).

Annals of the Deep Sky - Vol 9 is a comprehensive reference that guides amateur and semipro astronomers into every mind-boggling corner of the observational universe. Each volume presents extensive descriptions of prominent stars and deep-sky objects. No other popular work in astronomy provides the comprehensive historical background and astrophysical appraisals of prominent stars and celestial objects.

This volume is dedicated to the Milky Way’s nearest and largest satellite galaxies, the Magellanic Clouds. Throughout history they have been the subject of awe and wonder, catching the eye of Indigenous peoples of Australia and New Zealand, 16th century mariners, and astronomy’s pioneer observers such as Nicolas-Louis de Lacaille, James Dunlop, and John Herschel. In the late 19th and early 20th centuries, northern astronomers began traveling to the Southern Hemisphere to photograph, map out, and study the celestial constituents of what they referred to as Nubecula Major and Nubecula Minor. This book presents not only a thorough historical account of the clouds dating back 40,000 years, but also how astronomers’ ideas of the Clouds have changed over the decades — particularly on the Clouds’ origins, interactions with the Milky Way, and the quizzical aspects of star formation posed by their many unusual clusters and H II regions. Come discover the observational richness and astrophysical conundrums that are the Magellanic Clouds, true treasure islands lying just beyond our Galactic shores.

Annals of the Deep Sky - Vol 9 also includes two special fold-out maps for exploring the Magellanic Clouds in more detail, one showing the Large Magellanic Cloud and the other the Small Magellanic Cloud plus extra detail on the Tarantula Nebula, the star-forming region also known as 30 Doradus.

Author Jeff Kanipe has released the latest edition of this great series and for those of us in the South we are blessed. Volume 9 covers the Magellanic Clouds. Definitely will be in my Library of Southern Hemisphere books, can’t wait.
