This is a faint but relatively large PN in the constellation of Lynx. Since my telescope is only f/8 I had to gather a (for me) substantial amount of exposure time. Unfortunately, due to time constrains and the weather, I couldn't finish the project in one season, so this is the result of 3 nights of imaging done in 2 years (9/4/2021, 1/4/ and 19/4/2022).
Imaged through my usual 8 inch GSO RC I collected 31x10 minutes of data on this PN. Camera was a cooled EOS 700Da, filter an Optolon L-eNhance. Unfortunately, I had issues getting rid of artefacts by the amplifier glow, although I made new and correct dark frames. Instead of trying to fix it through processing, I simply cropped the image.
Stacked with DeepSkyStacker in sigma clipping mode (incl. dark, flat and bias correction with no factorisation of the colour channels), further processed with Fitswork (background neutralisation, alignment of RGB channels), Affinity Photo (curves and contrast, saturation) and Noiseware (noise reduction).
North is up.
