ASI585MC/MM 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 with low read noise at full resolution! It also features a high SNR and high sensitivity, especially in near-infrared wavelength. 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. Be aware that using a power supply out of this voltage range will probably lead to irreparable damage to the camera.

Why Choose ASI585MC/MM Pro?

One Camera for All

The STARVIS 2 technology brings ASI585 Series 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.

Large Full Well Capacity

The back-illuminated structure improves the camera’s full well capacity. Even with unbinned 2.9μm pixels, ASI585 Series 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

ASI585 Series 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

ASI585 Series 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 ASI585 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, ASI585 Series 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 ASI585 Series at the temperature from -20℃ to 30℃.

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 0.7e.

QE (Quantum efficiency)

Based on our testing results, the QE peak value of ASI585 is 91%.

What is in the box?

The Saxon 10" DeepSky CT Dobsonian Telescope （254/1200） features a powerhouse telescope with amazing light-gathering capabilities that's easy to use and transport.

This telescope is the retractable twin to the full-tube Saxon 10" DeepSky Dobsonian Telescope and comes with the same specs of 254mm aperture and a focal length of 1200mm. Featuring a collapsible truss-tube dobsonian design, the optical tube can be retracted into a shorter length and locked down to ensure secure and easy transportation. This scope also comes with a paraboloidal primary mirror to eliminate spherical aberration allowing you to see wide-field views of the Moon, constellations and deep sky objects such as the Great Orion Nebula.

Assembly of the telescope requires no additional tools. You'll be pleased with how easy it is to use the Saxon 10" DeepSky Collapsible Dobsonian Telescope with its Dobsonian mount. Simply swivel the telescope to the direction of your intended object and look through the eyepiece. This scope's Teflon bearing system in both axes with tension control handle means you'll be able to smoothly move your telescope to a precise location.

What is a Dobsonian telescope and why the tension control handle?

A simple, elegant form of an alt-azimuth mount made to carry a Newtonian reflector was popularized by John Dobson in the late 1970's. The Dobsonian mounted telescope is popular among amateur astronomers and telescope makers because of its simplicity. In its simplest form, the Dobsonian mount consists of a box which allows the optical tube assembly to pivot in altitude, while the box itself is swivelled on a base in azimuth.

The Dobsonian mount usually relies on the friction between the side bearings on the optical tube of the telescope and a frictional material on the saddle to hold the optical tube in place. If there is too much friction, the telescope is difficult to move to center an object in the filed of view. If there is too little friction, the telescope will not sty where it is positioned. This makes stabilizing the optical tube of the telescope difficult when using a Dobsonian mount, especially when accessories, such as a finderscope or an eyepiece, are added to the optical tube. As long as the amount of friction is at an appropriate level, and therefore stabilization of the optical tube is achieved, the telescope can remain in its desired position to view an object and maintain its position even when the mount is rotated.

The devices for stabilizing a telescope on the Dobsonian mount currently available include: a sliceable weight to counter balance the weight of the telescope, a friction lock that must be adjusted to inhibit movement of the telescope, and a spring attached between the telescope tube and mount to aid in stabilization.

These devices are inconvenient to use because they do not provide a simple and user-friendly way to adjust the friction. The objective of the saxon Tension Control Handle invention is to provide a tension adjuster that users can easily turn to add or reduce tension, thereby increasing or decreasing the friction between the optical tube and the sideboard of the mount.

By providing such a tension adjuster, the telescope does not need to be balanced in order to stay in position. The tension adjuster can be tightened such that the optical tube can stay in a position but can still be moved when prompted to adjust the position of the optical tube. Alternatively, the tension adjuster can be completely tightened to lock the optical tube in position.

Sky-Watcher 80/900 AZ-Go2 Refractor Telescope

The Sky-Watcher 80/900 AZ-Go2 is an 80mm Achromatic Refractor Telescope that come with a focal length of 900mm. It's an ideal size for beginners, offering views of:

• The Moon
• Rings of Saturn, moons of Jupiter (if in the sky when you're observing)
• Deep-sky objects including nebulae, star clusters and more

Images viewed through a refractor telescope have a classic quality that other telescope designs lack. Since a refractor does not use mirrors to view objects, you get a generally sharper image. Images are also displayed without the secondary mirror shadow, making it suitable for terrestrial viewing when used with a 45° erecting image diagonal provided. The 80mm collects around 130 times as much light as your eyes compared to the 100x times as much as the 70mm model. More light means sharper, clearer views.

The AZ-Go2 Mount – Wi-Fi-controllable with iOS and Android and compatible with SynScan hand controller, allowing it for smooth tracking and alignment. Use Wi-Fi to control the telescope wirelessly with your mobile device; smartphone or tablet.

Celestron has reinvented the Dobsonian telescope with StarSense Explorer—the first Dobsonian that uses your smartphone to analyze the night sky and calculate its position in real-time. This large-aperture Celestron StarSense Explorer is ideal for serious beginners and advanced observers alike, thanks to the app's user-friendly interface and detailed tutorials. It's like having your own personal tour guide of the night sky. The large aperture will ensure that you won’t outgrow the telescope as you continue on in your astronomical adventures. Advanced observers will appreciate the ease of use and spectacular views the StarSense Explorer 12” Dobsonian provides.

Dock, Launch, Explore

Leave complicated star charts, imprecise planetarium apps, and computerized mounts behind. With StarSense Explorer, locating objects has never been easier, faster, or more accurate. Within minutes of setting up the telescope, you'll be navigating the sky with confidence. Simply place your phone in the unique StarSense dock and launch the StarSense Explorer app.

After aligning your phone to the telescope's optics (a quick and easy procedure), StarSense Explorer generates a list of celestial objects currently visible. Make your selection and arrows appear on-screen, guiding you as you move the telescope. When the object is ready to view in the eyepiece, the bullseye turns green. As you observe, listen to hundreds of audio descriptions and view detailed information about thousands of objects within the app’s robust database.

High-Quality Altazimuth Base

An ultra-stable Dobsonian base provides a sturdy foundation for StarSense Explorer. It features large diameter altitude bearings with variable tensioning, Teflon azimuth bearings, and braces on the side panels for extra stability (unlike many 12” Dobsonian bases). The altitude bearings provide a smooth up-and-down motion while the integrated altitude "brake" system allows you to adjust the tension along the altitude axis for smoothest motion even with slight imbalances. The panning knob on the telescope tube provides an ergonomic grip so you can precisely point the telescope without introducing heat from your hands into the optical system. As celestial objects appear to drift across the night sky, you'll be able to easily follow them with minor adjustments to the telescope’s position.

Dazzling Views with High-Quality Optics

With a large 12" Newtonian reflector optical tube, this telescope has enough light-gathering ability to bring out impressive detail in celestial objects. You can expect sharp, bright views of Jupiter's four Galilean moons, its cloud bands and Great Red Spot, the rings of Saturn, the gaseous glow of the Orion Nebula, dust lanes in the Lagoon Nebula, and our neighbor galaxy, Andromeda. Compared to the other StarSense Explorer Dobsonian telescopes, the 12” Dobsonian has 2.25 more light gathering ability than the 8” and 2.25x more light gathering ability than the 10”, providing better views of faint objects.

All mirror surfaces are coated with our XLT optical coatings to visibly increase contrast and light throughput for brighter views. With XLT, you'll be able to discern subtle details while viewing the Moon and planets, as well as faint galaxies and nebulae. The mirrors are made of low-expansion optical glass, which helps ensure the best images under changing environmental conditions.

This telescope also comes with a high-quality 2” Crayford focuser. The Crayford design provides precise and smooth movements without focus shifting. It also includes a 2” to 1.25” adapter and a 2” extension tube, so you can use virtually any 1.25” or 2” telescope eyepiece with your StarSense Explorer Dobsonian. The focuser also features a thumbscrew so you can lock in the sharpest focus.

Perfect for the City or Dark Sky Sites

Even if you live in a light-polluted city location, the Celestron StarSense Explorer 12” Dobsonian is advanced enough to easily pick out Jupiter, Saturn, open star clusters like the Pleiades, double stars like Acrux (the "tail" of the Southern Cross, the Orion Nebula, Omega Centauri, and more of the best and brightest celestial objects.

But if you can take the telescope to an even slightly darker location, more objects will become visible. With this 12" Dobsonian and relatively dark skies, hundreds of fascinating objects are well within your reach.

Transporting your StarSense Explorer Dobsonian is easy thanks to the ergonomic carry handles located at the balance point of the tube and base. Dust covers are also included for the front of the tube and the focuser.

Smartphone Compatibility

Celestron StarSense Explorer works with most modern smartphones, including iPhone 6 and up, and most devices running Android 7.1.2 or later manufactured since 2016. For a complete compatibility list, click here.

Patented StarSense Sky Recognition Technology

StarSense Explorer uses patented technology and your smartphone to determine exactly where the telescope is pointed in the night sky. A Lost in Space Algorithm (LISA), like the ones satellites use in orbit to correctly orient themselves, helps the app match star patterns it detects overhead to its internal database.

While other astronomy apps may claim that they can help you find objects, they rely exclusively on the phone's gyros and accelerometers, which aren't as accurate as LISA technology. No other app can accurately tell you when your target is visible in the eyepiece.

Enhance Your Setup

Keep your phone charged all night while exploring with your StarSense Explorer by adding the PowerTank Glow 5000 to your must-have accessories (sold separately). This 2-in-1 accessory was made with the StarSense Explorer Dobs in mind, it has a red flashlight PLUS a USB power bank for charging mobile devices in the field. Connect the PowerTank Glow 5000 to the two posts at the front of the StarSense Explorer dock with the included bands so it is held in a convenient location for charging your smartphone while in use.

To achieve the sharpest views faster, we recommend pairing the StarSense Explorer 12” Dobsonian with the USB Cooling Fan for Dobsonian Telescopes (sold separately). The fan cools the primary mirror to the ambient outdoor temperature faster, leaving you more time to observe. It mounts directly onto the rear cell of the Dobsonian and works with any USB power source.

The saxon 30x80 Night Sky Waterproof Binoculars offer beautiful views of the night sky as well as expansive sights on land.

These floating waterproof binoculars are feature-packed:

saxon Multipurpose Finder Shoe Bracket

The saxon Multipurpose Finder Shoe Bracket is a reliable and versatile accessory designed to securely mount your finder or guide scopes onto compatible ZWO and Cassegrain telescope systems. Perfect for use with ASIAIR devices (ASIAIR PRO, ASIAIR PLUS, ZWO holder rings), this finder shoe ensures a stable connection and easy installation.

Crafted with practicality in mind, it includes two M4x8mm screws for quick mounting to flat or curved surfaces, giving you flexibility to attach it to the sides or back of your device. The dual knurled thumbscrews provide a secure hold, keeping your equipment steady and aligned.

Compatible with a wide range of optical systems, including Newtonians, Schmidt-Cassegrains, ACF, HD Edge, Meade, and Celestron models, the saxon Multipurpose Finder Shoe Bracket supports all finder and guide scopes with a standard Vixen dovetail foot.

Whether you’re setting up a guide scope for astrophotography or attaching a finder scope for stargazing, this accessory ensures stability and ease of use for a smoother observing experience.

The Celestron StarPointer Finderscope is the way to go if you want the easiest way possible to locate an object and center it in your eyepiece.

A red dot finder, unlike an optical finder, has 1x magnification, displays a super wide field of view, and keeps the sky right side up and left-to-right correct, matching what you see with your unaided eyes. An LED creates a red dot, superimposed on a viewing screen, so you simply point the StarPointer to the area or object you wish to observe, look through your eyepiece, and if properly aligned, the area in and around place you pointed the red dot will be centered in the field of view.

If you like the idea of having some magnification, try installing both a red dot and optical finder on your telescope. Schmidt-Cassegrain and EdgeHD telescopes have multiple mounting bracket holes so you can get the best of both worlds. Just make sure to align both of them correctly, and you’ll get the best use out of each of your finders.

How to Align the StarPointer Finderscope

The first time you use your finder, you need to align it. This one-time setup procedure should be done during the day. Take the telescope outside and find an easily recognizable object, such as a streetlight, car license plate, or tall tree. The object should be as far away as possible, but at least a quarter mile away. Move the telescope left and right or up and down so that it is roughly pointing at the object. Look through the telescope using your low power eyepiece and move the telescope until the object you chose lies in the center of the view. Once the object is centered in your eyepiece, turn on the red dot. With your head positioned about a foot behind the finder, look through the round lens of the finder and locate the red dot. Without moving the telescope, use the two adjustment knobs located on the side and underneath the finder. One controls the left-right motion of the dot. The other controls the up-down motion of the dot. Adjust both of these until the red dot appears over the same object you are observing in the eyepiece.

Your finder is now aligned and should not require realignment unless it is bumped or dropped. You can even take the finder off the telescope and reattach it while preserving alignment.

Tele Vue's Delos 4.5mm is a short focal length eyepiece that will deliver high power magnification. Importantly though it still achieves a generous 20mm eye-relief and wide 72° apparent field of view. Amazing in well corrected refractors with short to medium focal lengths. High powered views without the need for a Barlows or Powermate!

There is a good chance the TeleVue Delos will be seen as the ultimate combination of performance, viewing comfort and price. If you've been keeping a spot in your case for an affordable, premium eyepiece, you should consider a Delos - you won't be disappointed! Lessons learned from the tremendously successful Ethos series were applied to develop this long eye-relief, 72° apparent field of view eyepiece line.

The Delos 4.5mm has a standard 1.25" barrel making it suitable for almost any telescope or even bino-viewers!

Tele Vue Delos 4.5mm - Specifications

• Model # EDL-04.5
• Focal Length 4.5mm
• Barrel Size 1.25"
• Apparent Field of View 72°
• Eye Relief 20mm
• Weight 499g
• Field Stop 5.6mm

Background:

In 2011 Tele Vue introduced the Delos, mid-to-short focal length line of 20mm eye-relief, 72° apparent field of view eyepieces. Every optical, mechanical, and ergonomic aspect was rethought to achieve reference-standard performance for any visual application.

The Delos was conceived as a narrower field Ethos. Reducing the field to 72° allowed freedom to increase eye-relief, while controlling pupil aberrations, all without making the eyepiece too large. With Ethos performance standards as benchmarks, the Delos design achieves full field sharpness, virtually perfect f θ (theta) distortion mapping, and color neutrality. Image fidelity is maximized utilizing glass matched multicoatings and anti-reflection surfaces throughout the eyepiece.

Contrast is further enhanced with a new, continuously adjustable height eyeguard system that can be locked in any position. Since the Delos eye-lens measures a quite large 35mm in diameter, preventing stray light from reflecting off the first surface and extraneous light from entering your eye pays off in a nice increase in perceived contrast. The eyeguard's sliding action allows for positioning the soft rubber eyeguard at the ideal height to suit the observer's preference. Indicator marks on the eyepiece body are handy reference guides for setting your perfect position. The eye-guard can also rotate for Dioptrx users.

Reviews

Sky & Telescope Hot New Product for 2012 Award

Review of the 6mm & 10mm Delos from Astronomy Magazine, December 2011

Excerpts from Sky & Telescope, June 2011, review of Delos eyepieces:

WHAT WE LIKE:

Essentially perfect optics
"Immersive" observation experience

WHAT WE DON'T LIKE:

I spent several nights viewing the Moon, Saturn, stars, and nebulae with a variety of telescopes

The Delos eyepieces are "easy to look through … . They have flat fields, delivering absolute pinpoint stars from edge to edge with no hint of color aberration. The view, especially during the daytime, is very pure with no noticeable color tint. And there wasn't a hint of ghosts or reflections, even with the brightest stars".

"What caught me a bit off guard, however, was something that's best described as the observing experience. It was distinctly pleasurable."

"I have the sensation of looking out of a circular window rather than into an eyepiece."

— di Cicco, Dennis. "Tele Vue's New Delos Eyepieces". Sky & Telescope (June 2011). p. 58, 59.

The Accura Traveller 114 delivers serious light-gathering capability in a portable package. The 114mm Newtonian reflector collects enough light for detailed lunar observation and bright deep-sky objects, while  tube is still compact enough for travel.

The included 2x Barlow lens effectively doubles your magnification range, pair it with the included 10mm eyepiece for 100x magnification on steady nights.

Setup takes minutes without tools, and the full-length metal tripod with accessory tray provides stable support. The included red-dot finder gets you on target quickly. Ideal for observers seeking aperture and portability without compromise.

Introducing the new ZWO AM3N Mount

What's been upgraded? 

The ZWO AM3N solves a range of  astrophotography hassles

Streamlined Setup, Enhanced Mount Efficiency

Strain Wave Gear for Precision Control

Integrated Type-C and DC Power Ports

Based on ZWO's internal testing:

It is recommended to use a counterweight of ≤5 kg. When using a 5 kg counterweight, the lever arm should be installed within the range of 20 cm to 30 cm. 
For counterweights of other masses, the installation position can be calculated as follows: 
Assume the counterweight mass is m kg. The allowable lever arm length L is defined by:
10 N·m ≤ m × g × L ≤ 15 N·m where g = 9.8 m/s2, 
which can be approximated as 10 m/s2.
For example, if a 2 kg counterweight is used, the allowable range of L is from
10 N·m / (2 × 10 m/s2) = 0.5 m to
15 N·m / (2 × 10 m/s2) = 0.75 m.

saxon Solar Filters provide observers with a safe and easy way to view the Sun.

With a coated thin film that blocks sun rays and UV rays during your observation session, this solar filter minimizes the amount of sunlight entering your telescope, projecting a natural yellow-orange image of the Sun without any distortion.

All you need to do prior to your Sun observation is to attach the solar filter over the front of the telescope as protection for your eyes as well as the telescope's optics.

This solar filter fits 200mm aperture reflector/Newtonian telescopes.

WARNING! Do not attempt to view the sun without a solar filter. Looking at or near the sun can result in irreversible eye damage.

Sky-Watcher 127mm AZ-Go2 Maksutov Cassegrain

The Sky-Watcher 127/1500 Maksutov Cassegrain is a fully automatic telescope ideal for beginners and those who want to get straight to observing. Aligning the mount takes mere minutes with the “Bright Object” alignment mode with the computerised SynScan system that allows automatic pointing and tracking of more than 42,000 object in the sky! This means less time spent finding a faint nebula or a distant planet and more time to enjoy observing. Astronomy has never been so easy!

The Maksutov-Cassegrain is a compact and powerful optical design that combines a front meniscus lens and two mirrors. The optical tube is closed by the front meniscus, keeping the mirrors protected from atmospheric agents such as humidity, dust and pollution. The tube is short but the focal length is long allowing high magnification with the standard eyepieces. With maximum practical magnification of 256x , this Sky-Watcher Telescope will reveal details in Saturn’s rings, Jupiter’s bands, the Martian polar ice caps, and the phases of Venus and the moon.

The AZ-Go2 Mount – Wi-Fi-controllable with iOS and Android devices and compatible with the SynScan hand controller, offers smooth tracking and fast alignment. Use Wi-Fi to control the telescope wirelessly with your mobile device, either a smartphone or tablet.

Tele Vue Ethos SX 4.7mm Specifications

Introduced at the 2007 Northeast Astronomy Forum, Tele Vue once again broadened the amateur astronomer's perspective on the universe with: 100° of pure Tele Vue quality. The field area of this new eyepiece is more than 50% larger than an 82° field. The Tele Vue Ethos is essentially multiple eyepieces, delivering the true field size of a longer focal length, narrower apparent field eyepiece with the benefits of higher power and darker sky background.

We invited NEAF attendees to take a look and see the universe the way we think it was meant to be experienced, with a field of view incredibly wide and sharp! We were very pleased indeed by the response and validation of our design goals.
