Just one hour of total exposure time, caught in between intermittent clouds! The IMX585 mono sensor has some excellent sensitivity (around 85% absolute QE!) around the H-alpha, NII and SII wavelengths - this image is the result of just 20 minutes on each filter! I am blown away by the sensitivity of this camera.
