Hi Daniel

Your scope is looking great!

I have a 12 inch F5 and don't use a coma corrector. I have one but just don't feel the need for it so I don't think that's your issue.

I agree with Matt it's probably a collimation issue brought on in part by the tape. Check also for how stable your truss system is. It looks well made but I found with mine that if some of the knobs weren't tight enough the truss could slip a little.

I'm sure you know this but alight with the Cheshire first to check all the optical elements look concentric. Just use the laser for the final touch up.

I would recommend you join the ASV. You can do that anytime and members of the Instrument section can help you. They can also test your mirror. If you are in the south eastern suburbs, MPAS is a good group too with many helpful members.
