The 11002 chip really is big enough to benefit from a field corrector when it is used the manner that you are.
All that aside, that is a really good image... the opto-mechanics, guiding, framing, processing and seeing leave nothing to be desired.
I am impressed.

See I told you that the optics on these things are not junk.
I was being methodical in sorting all the issues over the many months before I started using this scope in earnest.
There is some very slight miss-collimation but the bulk of the elongation is is mainly field curvature and yes I am umming and ahhhing about whether to get an AOX or a field flattener. I have 75mm left in my back focus and cannot have both. The AOX is cheaper too. The field curvature would be nice to get rid of though.
