Rosetta Nebula / NGC 2237
I was/am so pleased with how my de-bayered SIGMA fp has performed that I couldn't resist going for a de-bayered SIGMA fp L (61MP). I finally go the chance to try it out in November, having managed to chase down a small hole in the clouds in northern Italy. The conditions were hard: The wind-side of the car was covered with ice before I had finished the set-up, so that I run out of juice before I could get all the data I wanted, nevertheless im still really pleased with the result. There is some really nice "smoking gun" effects in the S-II data that I wasn't aware of before (and didn't see in the 5 minute subs) so I will definitely be looking for an off-center composition next time i'm out ...
