Here is image of the double cluster in Perseus. Taken using TS 70mm ED f6 with a AA field flattener. You can see that the flattener is not working very well by looking at the top left and right corners. I have not been able to get the FF to work well with this scope.

I have the same problem jjB. Like me, you also have too many telescopes. This, or something like it, happens on each of my telescopes. I have learned to ignore it. Your image is very nice, it's a keeper, and if you hadn't mentioned it, most of us wouldn't have noticed. The Shed does have some very qualified imagers who can help you correct the problem if it can be corrected. Beautiful images like this, make our day. Keep posting.

Me are a spoiled lot :)
