Hi John. I cropped very little. Only a few pixels off the edges as I dither subs and there was some overlap. What you see is 99% of the total. Here's a single 30 second frame without any cropping for comparison.
These F4 scopes are unusable without a coma corrector. They are essential for reducing edge coma. I reckon the Baader MKIII does a pretty good job. Sorry, no pic of M42 without the coma corrector. Next time I'm out there I'll get one, but bad weather has set in for a while by the looks.
