Description

Here’s a shot of Messier 33 (NGC 598) is commonly known as the Triangulum Galaxy. Barely visible to the naked eye, this nearby spiral is the third-largest galaxy in the Local Group, after the nearby Andromeda Galaxy (M31) and our own Milky Way. This data was shot last September with the RASA 8 in my light polluted backyard using a LP filter to block out the street lamps nearby.

I have been using DBE in PixInsight and have been getting much better results with brighter targets. I also isolated the red channel using @astrobackyard ‘s method of noise reduction. Thanks Trevor.
