Horrible NGC55
Hi all
I took this on Sunday night from home, after spending considerable time drift aligning and getting the balance right.
I was able to get 2 minute exposures without trailing. Perhaps I could've gone longer but didn't try.
The sky wasn't very dark and there just isn't much dynamic range in the image. I took 15 subs @ 2 minutes each, and took 10 darks.
Saxon ED80 on EQ6, Canon 350D at prime focus. No guiding.
Focus wasn't spot on, either. Stars are slightly bloated.
1. Where's the colour? It's almost greyscale.
2. Using IP to subtract the darks ends up with black "spots" on the light grey background. ie: my avg'd darks seem to have white spots on them. I'll post an example later. Anyway so I have to use DSS which doesn't have this problem.
3. The second attachment shows the dynamic range problem? It shows up worsed when scaled down (50%). I left the background lighter to show it. What is this from?
Anyway I'm not very happy with it but I am continuing to learn so one day it'll all come together.
