Description

SH2-115 in Cygnus with neighboring regions. I only got 2 hours 45 minutes on this due to clouds and smoke, but the astro camera is just so much more sensitive than my old DSLRs. Shot with my AT60ED refractor w/ reducer, ASI2600MC, CEM40, and Antlia ALP-T Ha/OIII filter. I wanted to shoot with its twin SII/H-b filter, but that will have to wait for another night.

33 300-second subs, calibrated with 50 flats, darks, and 300 bias. Yeah, 400 calibration frames to calibrate only 33 lights, seems a bit silly.
