Not the best result, it was low in the sky and creeping into the London LP.  (Be glad to get back to my Astro campsite at Bortle 4).


Tried taking Oiii and Sii but there was only a faint whisp of Oiii at Bortle 8, so I didn't use it.  There was plenty in Sii so i combined that into the blue channel making this HaRGSiiB:


Atik460EX and Skywatcher Esprit100 

3 hours Ha (Baader 3.5nm)

30min Sii binned

35m RGB biined (in case the SHO didn't work out), but very little Green as it kept catching the clouds.

Total (without the Oiii) just over 4 hours




Amazing Carole !

Nice capture Carole, I like the star colour, the mix of RGB stars adds to the colour you have been able to create from the limited sub channels available to you. I was initially trying to understand what I was looking at as you have framed the Jellyfish very differently from the image I was working on  - now I've got my eye in with your image I like the framing as it takes the extremely bright propus (just) out of the frame and adds more of the nebula ...overall a good image to end the season with and given the LP conditions you are working under and low altitude of Sh2-248 .
