Title: My Tutorial Guide for Noise Reduction with TGVDenoise
Post by: kayronjm on 2014 April 20 18:49:55

This latest tutorial of mine explores noise reduction with the extremely effective TGVDenoise tool in PixInsight. Noise reduction algorithms in PixInsight have been officially assessed by the development team and TGVDenoise was found to be spectacular. Though extremely effective, it can be difficult to tame. This tutorial instructs you how to use TGVDenoise to reap its benefits without much hassle.

I appreciate you time and effort in helping all of us!

How would you add this to your DSLR/OSC workflow?  I suspect to replace ATWT and MMT? or after non linear for further noise reduction?

That's no problem at all, I enjoy doing this stuff!

Indeed, using TGVDenoise, I'd simply not use ATWT or MMT at all, either during the linear stage or after stretching. I'd still use ACDNR after stretching however, as you may need to regardless.

Do you have any issue with us downloading your tutorials to have on our local computers? If not, can you suggest an easy way to do this?

Thanks

I have absolutely no problem with this. As for the method, I'm not 100% sure myself. What I aim to do soon enough though is create PDFs of the tutorials and place them as download links. You could try "printing" the page using a virtual PDF printer, if you don't fancy going through the effort of copy-pasting into the likes of Word, editing and then printing as PDF when tidy (which is what I want to do, hehe).
