Possibly lost in my previous post, I found the culprit to my bad corners, and this was the outcome of a night's test.

Also was test for the Altair Duo Band HA/OIII 7nm filter.

 

1hr 45 total (21 x 5m), MD applied and flats, (possible gradient to the right)... but no ghost/comet stars in all corners, wahoo!
