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.
This image took a significant amount of time to post-process, since I simply could not decide on what to do with the data to achieve the colours I more or less wanted. I decided to go with the Hubble Palette and modify it as I usually do to turn it into the above colour palette that I find pleasing and contrasting to look at. I feel like taking a few panels to produce a second and third image from the same data, for the separate nebulae in different colour palettes.
Overall, there are 120 hours of data in this image in 240 exposures, spread over the 8 mosaic panels. Each exposure was 30 minutes long, as usual for me when I image a target with narrowband filters.
