I just put the skywatcher flattener on my Meade 5000 F6 APO 80mm and I took some 10s exp images with/without the flattener - can you tell which one has the flattener on ? Should I even expect it to work on my scope!

Spooking at the stars at the edge of the frames I'd say first has the flattener !? If not then there's a lot of distortion in the second at the edges!

Looking I meant ! Dam iPad lol

Thanks for looking .... The second one has the flattener!

It has more ca as well so not impressed - scope is 80mm f6 so I assumed it would be fine but it ain't. Is it faulty or simply not compatible ? Anything else to consider here before I send it back ?
