Refractor William Optics ZenithStar 103mm

My William Optics ZenithStar 103mm

General Description

Telescope brand:  William Optics
Telescope model:  ZenitStar 103mm
Telescope style:  Refractor
Focal ratio:  f/6.9
Telescope aperture:  103mm
Focal length:  768mm
This is my Williams Optics ZenithStar 103mm refractor telescope. It has a 50mm guide scope using an ASI290mm camera. It is also equipped with an Agena Multi-Reticle Reflex Finder.


I currently have a 28mm William Optics Swan 2" 72° eyepiece and a 40mm William Optics Swan 2" 72° eyepiece.
I am using RotoLocks for the tracking scope to hold the ASI290mm camera in place. I also have RotoLocks for both 1.25" and 2" eyepieces for the scope.
With the 0.8 William Optics Flattener/Focal reducer (6AII) the rig is f/5.5.

The main camera to use with this configuration will be my ASI533MM, which you can see mounted here along with the RPi running StellarMate OS. There is a 4TB external HD mounted below the RPi.
Yes, tracking scope needs to be straightened...that wasn't done at time of image.


And a few captures done with it.

There was a major failure in the hardware between the ring for the optical train and the actual tube scope. I ended up being able to repair it with J-B Weld, but it was not an ideal solution as I could have easily gotten the image train out of square. William Optics no longer offers this telescope nor any replacement hardware for it since it is simply a rebadged offering. The bad thing was, I had only used it about 20 times before the failure became obvious.

Image from after the fix.
