this is an as3 image done with an asi 290mc and a 2x barlow its full res so i had to use as3 as2 just keeps saying out of memory. I had reasonable polar alignment colimation was spot onseeing was bad but not the worst ever. also it seems to be on a lot of images it seems blurry. i did not select cropped if i do and it gets breezy or the mount is not perfectly aligned i get halff the image if i select crop in as3. its the same process iv used on some of my best clavius captures yet

It is usually bad seeing, poor focus, or poor collimation that causes my moon shots to blur. I am not sure how you can tell the difference by looking at the photos. I would guess it isn’t the camera.

Joe, it's a shame you deleted the video, because what you are seeing is a stacking defect.  This is visible throughout the image, basically everywhere.  I highlighted three areas with arrows below, but if you look over your image, you see this everywhere.  Every feature has been duplicated and shifted.  It looks as though an image shift occurred during frame alignment, possibly due to a poor anchor point being chosen in AS!3.  This was then passed down through the stack.  The double image is causing the blur.  The real data looks like it was good, and would produce a nice result if it was stacked over again with different parameters.
