Noise Reduction In PixInsight Tutorial 

Outstanding step by step of a complex process. Good rationale. Worth 30m...

Extraordinarily helpful tutorial! Instead of just whizzing through with a set of magic parameter values this tutorial vividly demonstrates the SYMPTOMS of poor choices of values ("ant farms", "tetris blocks" etc.) and shows HOW TO FIGURE OUT a good choice of parameter values to suit your own image. Bravo!

Really helpful. I'd been wary of this routine as it seemed so complicated, but you've demystified it for me. Thank you very much!

Best video on this topic that I've ever seen.

Outstanding video. Thanks!!

fantastic tutorial. Thank you.

Very helpful! Thanks.

Dave, best NR tutorial I’ve seen on MLT. You made one mistake I constantly do with MLT. You left the algorithm on Starlet Transform instead of Multiscale Linear Transform. This basically is the same as Atrous. I think the tutorial is still valid, the results might just be a little different.

Very helpful tutorial! Thank you for making this.

Thank you David! very helpful

Very useful and informative. Many thanks!

Very helpful!! Thank you very much ! :)

Awesome! Thank you.

Thanks for the video well done

Very helpful, do you have the info on the settings and exposure times on this image?

You saved my day :) Tks you so much :)

How did you get this nice black background at the finished result? I try to process the Orion nebula but I have a lot of noise in it and the background looks very grayscale.

Would be a good tutorial but the constant mouse movement, panning and zooming in/out is very distracting.

fantastic tutorial. Thank you.
