I captured this in spring when the object was already low above the horizon, and there was a full Moon during the hydrogen alpha imaging. So the quality of the original frames wasn't very good, and I didn't even try to bring out the outer parts of the nebula.
Well, thanks to the weather that I managed to capture Medusa at least like this after a cloudy winter.
