It has been a while since I used the SCT with the 0.6 reducer and OAG at the recommended distance. I found the reducer helped with better guide stars for the OAG but I was using the Celestron OAG. A guide scope is not really that good at that focal length. Do you have a Cut filter for your camera. My 183c really requires a UV/IR filter in addition to any other filter

Celestron + dreaded .6 reducer flattener
NEQ6 mount
82 x 120s subs
50mm guidescope - I cant get OAG working because of excessive coma (grr - hence my frustration with the reducer flattener)
ASI294MC Pro
L-extreme filter
Any tips on the reducer flattener?
All ideas welcome.
Backfocus is currently at 105mm - I've tried moving it closer and further - this is the best I can get...
What else is there?
