Dmack1 Posted April 22, 2021 Share Posted April 22, 2021 This was my second effort with the SW FF/FR (0.85) on the LX200 and from the coma correction perspective I'm really pretty happy with the result - this was a very slight crop just for dithering edges and there is essentially none of the awful coma I was getting with the Meade 0.63 (see bottom jpg). The stars are still not perfect but I think another mm on backspace may sort that, then it will just be down to tightening up on guiding. The image itself is could be better - high haze has meant that I have struggled to show much of the outer ring but maybe I'll get a clearer night to get some data to supplement that. Anyway this is 120 X120s Bin2x2, 8" LX200 GP on a wedge, ASI2600mc This is the sort of coma I was getting with the Meade FR - this is a STF stretch of the top left corner of my M51 image and really shows the difference. C&C appreciated. 5 Quote Link to comment Share on other sites More sharing options...
MarkAR Posted April 24, 2021 Share Posted April 24, 2021 Good effort, it's almost like three separate DSO's in one. Quote Link to comment Share on other sites More sharing options...
