IC443 - The Jellyfish Nebula

This one took a fiar bit of processing I don't mind telling you. I've tried to pick up the faint OIII emission surrounding the main Ha luminance - just about acheived it. Taken with the C8+Hyperstar+178MC Cool - 4 hrs of integration ??

So Chris, you're using these filters on a OSC camera? I think I will give that a try (when we get another clear night!)

Great image by the way!!

Hi Ron - thanks- I'm using a duo narrowband filter that gives me 2 bands in one shot - Ha in the red channel and OIII in green\blue. Its more convenient for my setup because I can't run a filter wheel on the Hyperstar - and it's a time saver. I then extract the data in Pixinsight and follow the steps for a HaOO bi-colour image. I'm sure the guys on EMS would argue sensitivity of mono cameras over OSC for narrowband but I don't think thats too great with these modern chips on cooled CMOS cameras nowadays. Good luck and hope to see your results

Thank you Graham - I got lucky - the Jellyfish was dry all night and I managed to get midnight-4am on M51 (still proessing that one but it's looking good too)
