Collimation Aid for SCTs

Post by wcblack7 » Fri Nov 09, 2018 1:39 am

I was wondering if you could expand the experimental collimation tool for Newtonians to include something for SCTs (or maybe add a different tool).
Showing an average diffraction pattern and measuring the FWHM of a single star at prime focus works great for this.
I suppose you could just stack frames and get an idea, but a tool that would help by showing you which screw to adjust would be cool.
I'm not sure if you are familiar with MetaGuide, but it does something like this and its great to have with a catadioptric telescope where the mirror may shift slightly when you move from target to target.
