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.
