Hi! I'm an AP noob trying to figure something out. I chose the Lagoon Nebula as a target. I used a Fujifilm X-T20,a vintage 135mm f3.5 Super Takumar on a manually operated barn door tracker (type 1) to take 240 3-second exposures, for a planned total of 12 minutes. (ISO 1000) Using Deep Sky Stacker, I processed those images and added 10 darks and 10 offsets. 10 flats were planned... but I forgot to shine a light through my white fabric, so those were left behind.
Problem is... the final TIFF file in DSS doesn't seem much nicer than the indiviudual RAF (Fuji RAWs) files. M8 does stand out a bit more, but not that much. What annoys me the most is the fact that, at the end on the stacking process (it took hours!), it seems that only 7 images were stacked! [I use the French version, in case you wonder.]
