Description

I'd never tried using Pixinsight HDRComposition before with DSO data so since the Moon is pretty much washing out my targets I gave it a try on M42 with 15s, 30s, and 60s exposures. The Moon made the fainter outer areas noisier than they would have otherwise been so I will probably give it another shot on a dark night.
