IC443

I have to admit this is maybe a bit too dim for my gear. I am still a bit surprised how well I captured the faint gas clouds in the surroundings. There are huge halos around Mu and Eta Gem. I think those are reflections from the camera to the filters and back. My filters are pretty far from the sensor which could be reason for such large halos. This might also be one contributor to the poor edge performance. Weather was changing throughout the exposure. Eventually Clouds covered the guidestar and caused the system go nuts.
