Some little processing to share with the forum

[Philippe B.]

Thank you for sharing your processing.
Very nice image ! The best one I saw from an DSLR.
Cheers

Thank you everybody!

It happened also to me that the site sometimes was not accessible. Probably it is a problem of the hosting. If it will continue to happen I will change the hosting to one more reliable.

For the MMT I always use a trial and error approach, and also in this case I've applied it one layer at time, beginning with the first layer and setting the threshold and the adaptive parameters; in case the denoise is too excessive I then decrease the amount a little.

And I always use a preview to speed up the procedure. Then I apply the tool to the whole image.

Going back to the workfolw, a thing that I have seen is that at the end of the whole process, the "luminosity" of the image is always affected, expecially for the stars that lose their sparkling. I think that some processing of the "small scale" image too must be made, in order to keep high the stars brightness after the sum with PixelMath.

I will try to get more into it when I'll process the orion's belt image (the other I took the night of M42 field). I made a quick process of it and I posted it on the site, but I want to restart the processing from the beginning, including also this new aspect about the highlights. If you wish you can find the image here (it's only in italian language, sorry  )

When I will be done with the processing of the Orion's Belt I will put everything online.

Thank you for sharing. It helps processing data very well!

Emanuele, looking forward to your second installment.  These extensive processing tutorials are Pixinsight jewels and should be treated at such with some type of permanent repository (same with scripts) so it's much easier to find them in the future by veterans and newbies alike.

Here's to hoping this will become a reality.

I will also thank you for your work with this workflow tutorial. I was looking at it last night and it's very interesting indeed. I will be trying it with my Orion Nebula data.
