Standing on The Edge of the Lagoon
I'm quite surprised at how well this turned out for a mere 35 minutes (7 subs) of data. It's a nice bright target like that, but I was even shooting at F10 with the full focal length of my c9.25 EdgeHD SCT (2350mm).
The coma in the corners bothers me a lot and I did notice some drift even though my tracking was perfect and locked on steady, so I believe I have some flexure between the OTA and the guidescope. I'm hoping an OAG helps that somewhat.. the field should be flatter than this with the Edge HD series shouldn't it?
