M109 galaxy
Taken with a Seestar S50 from my usual bortle 9 location (Paris city center), about 20 hours of integration with an Optolong L-Pro filter. This time was no different in terms of the crazy gradients I got in my original stack, but I managed to remove them, quite happy with the result :)
Equipment and acquisition:
\- Seestar S50, EQ mode, 30 sec exposures
\- Optolong L-Pro filter with a 3D printed filter holder
Processing (PI and Siril):
\- WBPP, 2X drizzle
\- Dynamic crop, SetiAstro AutoDBE
\- SPCC
\- BlurX, NoiseX, StarX
\- Starless: Initial setiastro statistical stretch; then a first manual curves transformation stretch with a range mask to reduce the residual background; after that, more curve transformations with range and color masks; createHDR image
\- Stars: setiastro star stretch, then manual curves transformation to tweak color and saturation
\- Star recomposition in Siril, final NoiseX and color adjustments in Lightroom
