This one I had to work hard for! Dealing with winds gusting to 30mph (which plays havok with the guiding system I use to keep my mount pointing at my target very accurately), I spent two nights capturing the data for this target.

I then spent 2 full days to process the result, trying to get the colours to balance in a pleasing way, trying to deal with the very bright star in the middle-right of the frame. I think I gave up and restarted the whole process at least three times before ending up with an image that I’m still not quite happy with (until the next reprocessing attempt!).

IC443 is a supernova remnant in the constellation Gemini.
