Seeing someone making a video about postprocessing with GIMP is such a rare thing nowadays! As an OSS supporter (and long time user) I must say thank you very much for this video :)
This is highly appreciated, please keep up your fantastic work and the use of OSS !

@rbnye

Really a great resource 1 and 2b (since I use Gimp). Made the pre and post processing very clear and added ideas I hadn't considered. Thank you for taking all the time to put this (and your other videos) together. Will be adding you to my Patreon donations

I did a test of this technique by taking some images the other night. I live under Bortle 8 skies and the moon was over 80% full. I took only 105 light frames because Orion was starting to set behind a tree. 

Even with all these obstacles, I am still completely blown away by the results. 

I can't wait to get under some dark skies to try this again!

@felipefonseca1212

You can’t even imagine how much this has helped me! I only have a DSLR and was waiting to get a tracker and telescope, but now I’m gonna try getting my own images right away or process your samples. Thanks again!

@stuboyle666

Nico, keep up the great work.  What you are doing is way more informative that what I'm getting from other astro channels.

@ckastronomy2920

One of the most useful astrophotography tutorials ever. Following along with a 18-55mm kit lens & old canon 550D dslr. Hoping the result will come out well.

@ezrayarmush554

An alternative to the gradient removal by using a gradient is to blur a duplicate layer (gaussian blur) by a few hundred pixels, paint out any stars, then blur it again and use subtract blend mode. Works like a charm!

@A_B_Ph

Such  an amazing and perfect tutorial! As a total beginner I really appreciate this approach. Thank you for your outstanding lessons.

@haythemhamdi3995

Great video very very helpful never thought I could process a deep sky image without using Photoshop and spend that money at least for now I just processed my first deep sky image of Orion thank you for this great video.

@angelsalas7884

Awesome video and very well explained. I'm just starting with astrophotography (2 weeks ago I bought a DSLR camera) and your videos are helping a lot.

@onionboy7461

Just found the first part today and now part II. Big thanks! Gonna try it out asap

@JorgeDavalosBravo

Thank you very much for processing it in PS, PI and also in GIMP... Excellent work !

@luizbertini5458

Thanks a lot for making this video. I learned a lot with you and certainly my astrophotographs got much better.

@laurenwade4770

Thanks Nico.  I have tried to take Orion photos before and not got anywhere near the results I wanted.  Tutorials are so often in Photoshop which I don't have, so you try to get the software you have to do what is described.  This time took 900 x2 second exposures with my 100 mm macro on a Canon 70D.  The Orion nebula can clearly be seen in single exposures, much better with multiple.  Thank-you for taking the time to do your videos in multiple formats.

@Bazzasphotolife

Fantastic contribution. Thanks so much for these tutorials. Can't wait to try it!

@drrach1

Thank you very very much for this!!

@eckebusch

Thanks Nico, that's exactly what I was looking for. Awesome video. I just started with astrophotography and this video is a game-changer for me as I don't wanna buy photoshop ;)

@mabdinur85

You should give Siril a whirl as an alternative to DSS. It has a batch processing scripts that you can do stacking with a single action.

@sdsparkes

Please, please repost PT1 of Orion with a DLSR, or the whole video I watched it once all the way through and it was brilliant but to much to take in just watching once. If I’m going to pull this off I’m going to need hand holding and your guide was the most informative I’ve found for someone new to Astro DLSR photography.

@superchief1171

Thank you so much for that i use gimp and was wondering for ages how to get rid of light pollution on my milky way image and how to make it show more. Im going to try and apply this tonight.
