Description

Humble attempt to image M20 - The Trifid Nebula. This is from my backyard in the heart of one of the 4th largest cities in the US. It's definitely Bortle 9 sky. It's amazing what you can do with current sensors. Just used an IR/UV cut filter and short exposure. I kind of figured that imaging from the city is a battle between noise and data. My perspective is that it's pointless to go for a lot of gain or exposure, since at the end you will be capturing more noise.

I processed the subs in PixInsight first. No calibration. Use AstroPixel Processor to remove light pollution. Minor adjustments in Photoshop. No noise reduction (other than APP).

Enjoy and please critique.
