How Flat is this looking?

[Earl]

Any comments on the flatness of this would be greatly appreciated.

Not sure exactly what you mean by "flatness", but if I enhance the contrast in PhotoShop Elements 9, I can definately see a halo around the bright star in the field, and part of a halo from another bright star just off the right side of the field. There is a color cast, tending toward green in the picture, as well. Is that what kind of comment you are look for?

Just wanting to check the flattener is doing its job, it looks ok to me, but i have seen some images which show how its working.

PixInsight aberration spotter shows an artefact in the top left (circular), bottom left (yellow tinted glow), there's a faint meteor trail across from top mid to bottom mid right and another large artefact (possibly halo from another star) to the right edge of the image. It takes a massive stretch to see these though.

Otherwise the illumination looks pretty even across the image.

You can download CCD Inspector for a 30 day trial to check the curvature, Earl
