Dolphin Head Nebula - edit more data

Nice to get an image out, seems to have been an eternity.

Never thought it would be so difficult polar aligning on decking but there you go. Interestingly in the recent storms a large section of eucalpyt broke off and i have a direct line of sight to the SCP, so actually decided to use SharpCap to polar align. seemed to go ok.

This is about an 1hr 15 of 03, about 5 mins of stars. The Ha blend (third pic - another hour 15) but I'm having flat issues (concentric ring issues). perhaps it is a stray light issue in some of the subs.

now that i have PA going ok and the reflections less of an issue, i will need to get back to flattener spacing.

might grab some more data tonight.
