Dark Nebulae in Cepheus
One of my favorite regions of the sky - the Dark Shark Nebula (LDN 1235), LDN 1251, and the Wolf's Cave Nebula (vdB 152). It's a tricky region to process - the dust is faint and the stars are plentiful. If I shoot this again with the my Samyang 135, I think I'll stop down to f 2.8 to flatten the field and shoot 90-120 sec subs. I had problems with the not-too-flat field in post processing. I've cropped it to minimize the non-flat-field color artifacts.
Acquisition details: Fujifilm X-T10, Samyang 135mm f/2.0 ED UMC @ f2.0, ISO 1600, 84 x 60 sec, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker, editing with Astro Pixel Processor and GIMP, taken August 14, 2020 from Bortle 2 skies.
Nov. 2020 update: I added my Sept. 26 2019 imagery (50 x 90 seconds, better color) to my 2020 imagery (84 x 60 seconds, better skies). There's still some color weirdness, but the addition of the 2019 with better color helped modulate the color weirdness of the 2020 data. I might still end up cropping it, but at least the color is a bit better. Perhaps I'll shoot this area again next August or Sept.
