Two months after starting, I have finally been able to finish imaging my large, 8-panel mosaic of Cygnus, including the IC1318 Gamma Cygni Nebula and the NGC6888 Crescent Nebula. This project has been finished in good time as Cygnus itself is starting to disappear off the Western horizon significantly early into the night these days. This started as a narrowband bicolour image but a friend convinced me to capture Sulphur-II data as well, so here we are.
In the numerous years I have been doing astrophotography, and indeed in the one and half years I have been doing it remotely, this is my very first image of a dark nebula, the LBN603. I was expecting a weak signal from a dark nebula so I expected that perhaps 15 minute exposures would be better than 10 minute exposures. Indeed other images of similar targets showed me people pushing the exposures for longer, so I did the same this time.
