Tarantula Nebula. Remote from Australia.
20 inch Ritchey–Chrétien. RGB all 600 seconds. Ha, Sii,Oiii 1800 seconds. About 3 frames per filter. It was a very quick process. RGB combined into one image, Narrowband into another and then a simple blend of the two.
Carbon fibre upgrade to the 10" is working well. It appears to be impervious to temperature change and images show very round stars.
Baader coma corrector is in use so satsr remain round even to the edges of the frame.
