Ultracat 76 WIFD

This William Optics Ultracat 76 mm APO Astrograph is a premier tool for astrophotographers. With a 5-element advanced-Petzval optical design, including super-ED and lanthanum glass, and a fast f/4.8 focal ratio, this telescope delivers stunningly sharp, flat-field images across its 50mm image circle. Optimized for Full Frame, APS-C, and M4/3 sensors, it also offers compatibility with Medium Format cameras for outstanding wide-field astrophotography.

The patented William Optics WIFD focuser boasts flex-resistant construction to prevent image shift or tilt, and is superior to conventional focusers—especially for heavier loads. Its smooth rack-and-pinion design provides super-fine adjustability for critical focus. Because of this new approach to the focuser, the telescope's improved weight distribution allows for better balance during imaging sessions.

Specifications

AM3 Mount

ZWO has designed the AM3N mount head to be an astrophotographer’s dream mount! While incredibly portable, it also has many features, like the two control options, the harmonic drive speed reducer and synchronous belt, and more that make this mount a must-have tool for your imaging sessions. Check out some of these features below!

Dual Mount Style
ZWO has designed the AM3 mount with the capability of switching between equatorial or alt-azimuth mount modes. You can switch the mode through the included hand controller or through the app on a smartphone/tablet. The body of the mount comes with a status light indicator that will indicate whether the mount is in an equatorial or alt-azimuth mode. The red light signals the AM3 is in EQ mode and the green light signals the mount is in Alt-azimuth mode. The equatorial mode is great for tracking and imaging celestial objects while the alt-azimuth mode works well for observations.

Two Mount Control Options 
When it comes to controlling the AM3 mount, astrophotographers can use the included hand controller or use the WiFi connection and wirelessly control the mount from a smartphone or tablet. Included is a rocker-style hand controller. The size of the controller makes it easy to hold and use while the rocker-style design allows the mount to be pushed in multiple directions. For the wireless control function, users can utilize the integrated WiFi network emitted by the hand controller and use Tonight's Target, GoTo, Live Preview, and others to pair with the ZWO AM3 mount. Please note that in order to utilize the WiFi, you must plug in the controller to emit the signal. Known iPad Compatibility - The mount is compatible with iPads running iOS 12 and up, including iPad/iPad mini, iPad Air, and iPad Pro. To use the Sky Atlas app feature, you will need a device with at least 6 GB of RAM

Harmonic Drive Speed Reducer and Synchronous Belt
The incorporated Harmonic drive speed reducer and synchronous belt allow this mount head to have precision control. While a traditional equatorial mount requires counterweights for use, this ZWO mount's harmonic drive speed reducer and synchronous belt eliminate the need for counterweights, though they can be added if desired (an M12 thread interface is available for compatible, user-supplied counterweight shafts). Having this design allows for more accurate control and a reduction ratio of 300:1. If counterweights are added, then it should be secured on a counterweight shaft that is no more than 20cm in length.

PE Curve Performance Guaranteed
The design of ZWO's strain wave gearing system is the result of ZWO working with well-known manufacturers, and it was developed with the needs of astrophotographers in mind. Just some of the amazing features of the ZWO AM3 mount that makes it a must-have addition to astrophotography setups are the very low periodic errors, smooth gearing, and high torque. ZWO measures each mount and equips it with the exclusive PE curve before it leaves the factory to ensure performance is guaranteed.

0-90° Latitude Adjustment Range
This ZWO AM3 mount comes with a latitude adjustment range of 0-90°. For the first gear, adjust the pitch angle grip to achieve between 0° to 60°. For the second gear, loosen the hex-head screw and adjust the pitch angle grip to get between 45° and 90°. Not only does this allow astrophotographers to use the AM3 in alt-azimuth mode, but it also allows those in both low and high-latitude locations to use this ZWO mount when in equatorial mode.

ASI2600MC Air

The main sensor IMX571 features an APS-C format and 26MP total pixels. The size is 23.5mm in width x 15.7mm in height, and the diagonal is 28.3mm. The 3.76um x 3.76um small pixel size accommodates an impressive full depth of 50ke. With the new hardware technology, it is even extended to 73ke.

Guide Sensor

The SC2210 sensor taken from the ASI220MM Mini camera features very high sensitivity. The QE peak value reaches 92% at 500nm. The read noise is as low as 0.6e. As the new generation of guide sensor, it has achieved great results in guiding, proved by hundreds of astrophotographers.

Start Your Astrophotography Journey with Great Convenience

The ASI2600MC Air combines guiding, imaging, and smart control into one compact, lightweight device. Say goodbye to complex setups and enjoy a seamless, hassle-free astrophotography experience.

Effortlessly Connect Mutiple Devices

4x USB2.0, 3x DC12V 10A, 1x USB Type-C
USB 2.0 ports for your focuser, filter wheel, and mount; DC 12V 10A input/output ports for reliable power; and USB Type-C port for fast file transfers—you can focus on capturing stunning images without worrying about connectivity issues.

Shoot with Confidence: Ample Storage and Stability

With a massive 256GB eMMC storage, the ASI2600MC Air allows you to capture multiple targets with ease. Rigorously tested with over 300 benchmarks, it ensures system stability. Plus, the USB 2.0 ports support up to 1TB external storage, giving you plenty of room for all your astrophotography needs.

Dive into the Rich Details of the Celestial Targets

In expanded mode, the full well capacity of this camera reaches 73Ke, which is 1.46 times of that of the IMX571 sensor (51ke), making long-exposure shots less prone to overexposure. The large full well capacity and high dynamic range make capturing both light and dark areas with stunning clarity and detail possible. Witness the miracle details and colors of targets like never before!

Dual-Band Wi-Fi for Stable Signal

Experience unparalleled connectivity with our enhanced external dual-band antenna, supporting both 2.4G and 5G frequencies and offering stable and smooth usage within 20 meters.

Cross-Platform Device Control

Except from ASIAIR App, ASI2600MC Air can also wirelessly connect to ZWO’s proprietary PC control software, ASIStudio, and also other 3rd-party PC software. 3rd-party software can be controlled through ASCOM extended protocol Alpaca (requires ASCOM Platform version V6.6 or higher).
