Description

Cloudy weather hath returned to haunt the evening realm. So I figured let's get some practice in and in particular practice with PixInsight noise reduction. I have always struggled with NR. It seems that when I use NR it simply shift the noise from small scale noise to large scale noise...ANNOYING!!

I recently saw a tutorial by Jon Rista that uses TGV Denoise and MMT along with a couple of different masking strategies (man, I have been doing masking all wrong). After trying it out all I can say is WOW! The difference is night and day.
