I have a Celestron EdgeHD 8" scope with Hyperstar and ZWO ASI294 that I use for astrophotography/EAA. The cables to communicate with and power the camera must run in front of the corrector plate which can cause spikes in the images.

I came across this other project here on Thingiverse which is the same idea: a way of routing the USB and power cable for Celestron SCT's with Starizona Hyperstar using a 180 degree arc to avoid the spikes.

My design is a bit more robust and is specifically designed to work with the flat USB3 cables that ZWO includes with all of their cameras while maintaining the a 4mm width of the arc even with the cables. The original design also has a tendency to "tip" which can increase the amount of obstruction.

You may either glue the cables to the arc (contact cement or "Goop" recommended) or use something like electrical tape- however, electrical tape may not hold up over time and leave a sticky mess on the parts.

Please note, I'm happy to upload STL's for other scopes if you can provide:

• The diameter of the front ring of the OTA
• The thickness of the front ring of the OTA
• The diameter of the Hyperstar
