The third image from my dark site visit last weekend - NGC253. I was inspired to chase this from other posts I saw on this forum recently.
ISO800, 39 x 2min subs, 31 darks, 20 Flats/Dark Flats.
This was difficult to take as I had trouble just finding a guide star. And when I did, I couldn't seem to crack 2 min subs without errors appearing. I dropped back to 2 min for more success (I took 44 I think, so not too bad).
This has been cropped. The original had a number of artifacts on the side - I think reflections again. I may also reprocess this one again with a better selection of darks (and maybe separate groupings) as the temperature range for the light images varied significantly.
Anyway, for my first galaxy pic, I'm pretty happy.
