12 Jan IC443 – The Jellyfish Nebula
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 finally happy with (until the next reprocessing attempt!).
IC443 is a supernova remnant in the constellation Gemini.
