I know I won't finish this one this week so putting it out there before we meet again.  Imaging Sh2-224 in Auriga in Hydrogen Alpha and Oxygen III and RGB.  Ha is pretty easy; OIII less so.  Image below does not have any OIII yet...

Hello All

Finished the above last night after the rain last week!

Beautiful supernova remnant in Auriga. The Ha channel is easy enough to get but after 11+ hours of OIII, it barely shows in the outer shell. Calibrated RGB stars add a nice - Christmas-like - colours to the overall picture.

Happy Christmas and best wishes for the New Year to All!

Looks a really faint target Roberto, well done getting it from Petts Wood.

Thank you Carole! Yes difficult target but the Ha helps.

I wonder if it would work with Oiii and or Sii from your location.

The second version has 11 hours of OIII and it barely shows...
SII is stronger but I was after a bicolour image this time around.
Thanks

Oh yes, on closer inspection I can see it now.

Have checked on Astrobin, and the Oiii is only at the extremities anyway, and people are saying it is very very faint, so this was quite a challenge from a LP location.
