This is a little over 6 hours of exposures on the Seagull Nebula split across three filters. I shot 21x8m Oiii (2h48m), 18x8m Sii (2h24m) and 17x8m Ha (2h16m) using my Askar 600 at f3.85 and an SBIG8300 at -20*C from the balcony.
I calibrated with darks and bias frames, but wasn't able to grab flats for this project.
