Description

60 x 180sec light frames from light polluted backyard through Altair CLS-CCD filter. M101 was at zenith throughout the session.

First light with new camera, and first time using OSC post-processing. Definitely NOT a prize-winner or APOD by a LONG shot .  Light frames were pretty noisy, partly due to city lights, partly due to CLS filter (maybe I'm using it wrong?), and partly due to my unfamiliarity with OSC post-processing in PixInsight.

PI removed a LOT of the noise, but there's still lots left in this image, and I didn't work too hard at eliminating it once I had a presentable image. When I get better at OSC processing, I may revisit it - or maybe I'll leave it as a benchmark of where I started, for future reference.
