The ED 80 does not come with that sort of focuser or accessories. So you have a mismatch. But you can crop the bad bits out.
Also it seems you have some tilt happening which is making it harder.
Software won't correct it although you could try using Lightroom with lens correction and perhaps the distortion slider. I might improve but will not fully handle it.
I went though all this years ago with a Tak FS152 2.7 inch focuser which was not adequate with an SBIG STL11. When I upgraded to a 4 inch focuser and 4 inch flattener all was well.

That's excellent information Mr Bradley. I really appreciate you taking the time to comment.
I do wish that when I was discussing the purchase of this camera with the retailer that they made this focuser size restriction clear to me. Basically, about a third of the sensor is "unusable".
OH WELL! We live and learn.
Cropping the images is a good solution me thinks
