Hi all
Last night was absolutely freezing but at least the sky was clear, I managed to get 2 hours for each filter in 10 minute unguided subframes before it sank too low in the sky.
It was taken with my TMB 115 f7 with matching field flattener, FLI filter wheel with astronomik Ha, OIII and SII filters, Starlight Xpress H36 camera and Paramount ME. I used simple autodark subtraction in Maxim DL and no flats or bias frames were used. It was combined as an RGB image using the HST palette with a weighting of 3:1:2 for the respective RGB channels.
I have posted the full widefield image here but I have posted a couple of cropped closeups on my website
http://www.imagingtheheavens.co.uk to show the central core of the nebula and also the "Ghost Nebula" in more detail
Thanks for looking
Best wishes
Gordon
