First true light with the ED80. I definitely need a field flattener, even with a small sensor.

I tried fixing the distortion at the edges using Free Transform > Warp. I'm curious to see if this will plate solve now. At any rate, it looks like my focuser was still not square with the scope. I just tried fixing it with a laser and mirror, so hopefully I can use this scope without a field flattener (at least with the smaller chip of the 183C if not also the micro 4/3 sized sensor of the ZWO ASI 1600).
