Having problems with bright stars near to edges on my images,as you can see from the image I get strange loops the equipment used on rear off my celestron cpc800 are as follows celestron 6.3 focal reducer correcter,baader sct to 2"" adapter then modified(filter removed) canon 1000d with astronomic cls clip in filter,any idears how to cure this,should I use 1.25 visual back to camera instead

I had similar problems on my old Tal-1m

I solved it by adding baffles to the main tube.. a little harder on a schmidt cassegrain.

The reflections are probably caused by the scope not the camera/corrector/filters, so I would try and track down other owners of your OTA and ask them... I'm guessing the solution will involve flocking,

Thanks for the help.It looks like flocking the baffle dose help so will give it a try,it seems the more bright stars in the image and exsposed for a length of time causes the problem.
