Redcat51 on AM3 Mount

Scope: The main scope is a Williams Optics Redcat51. The Redcat51 is a 51mm aperture (diameter) scope with a focal length of 250mm. It gathers light relatively fast at f4.9. And the Petzval design means it isn’t very Putzy, no back focus or flateners required.

Camera: The Camera is the ZWO ASI 533MC pro. It is a color camera that has a cooling element to keep the sensor at temperatures as low as -10 degrees C which reduces imaging noise.

Autofocuser: The autofocuser is a ZWO EAF, which requires a special mounting system that I 3d printer since the scope has focuser like a camera lens.

Equatorial Tracking Mount: The AM3 tracking mount is a lightweight design that uses strain wave motors.

Imaging Computer: The black mini-PC mounted below the scope is a Mele quieter 3 which is a fan-less low power Windows PC. It is ideal for astrophotography because there is no fan vibrations, it runs on 12V, has a solid state drive for storing images and has the necessary USB connectors for connecting the cameras, focuser and mount.

Guidescope and Camera: On top of main scope is a ZWO 120mm focal length 30mm aperture scope with a ASI ZWO120MC camera.

Dew heaters: and finally both the guidescope and main scope have green dew heaters wrapped around them that prevent the scopes from getting covered in dew overnight by keeping the temperature above the dew point.

Tripod: The tripod is a very lightweight carbon fiber design, but it requires some weight to be placed in the lower bag for added stability when used with larger payloads. Some people use rocks or water bottles, I have found that my lithium battery pack works pretty well as weight when I use this tripod with the my Celestron 6 in reflector scope.

Battery Pack: The lithium ion battery pack provides 12V DC at up to 10Amps and will run this whole setup for over 8 hours.
