Well....I'll just show you my worst one ok ??
You have me beat with that image scale mate. I've got a few using the 2X barlow, diagonal & 2 extension tubes, & boy was it hard to capture!
I'm getting that debayer cross-hatch on all of the big ones though & I don't know how to fix that, never come across it before!
This one is the first one I captured with the onion I was raving on about earlier.
