    Thank you so much for this! One of the best Siril Tutorials I've ever seen. Very clearly explained and it's nice to learn how to have a lot of control over all the processes!

      @@robj144 If you don't mind me asking, as I'm working with Datasets from Telescope Live, more specifically LRGB, at which point in your workflow would you bring in the Luminance layer? Thanks!

    Good demo. I'm muddling my way along with Siril, Graxpert and Affinity; I appreciate the descriptions of what the tools do and how/when/why to use them. I'll be watching for more. Thanks.

    Great video. I've never seen this kind of process before in Siril, but you are clearly getting more control this way over a traditional bug stretch. Definitely looks more tedious, but worth it. Thanks

    Thanks super informative, great stuff. You helped me with a photo I took of the crescent nebula and sadr region it's great to have a visual of what you were explaining. 😊 I thought I understood but after watching this I had an idea but still a ways to go lol.

    I've been using Siril for stretching and playing with deconvolution with mixed results. Your explanation of how you use these tools gives me hope that I can do better, especially with using GHS. Thank you!

    First of all, your voice is more than fine for presentations and teaching. Very informative and well presented.
    Second, thank you for processing my data over on cloudy nights.
    I've been following the instructions from the normal players here on youtube, they are good but none of them were showing how important it is to do lots of micro stretches while protecting the highlights. I will be processing my data again with this method and will use arcsinh transform function. Very nice.
    It was also interesting to see that you didn't use the AI back ground extraction. When I used it I could see the gradient was pulling color from the nebula and didn't know how to prevent it. I'll doing it manually on my next attempt.

    Hello Rob, great video and very helpful. I noticed quite an issue though on my end. I'm following the exact same steps you are but im having issues with starnet removing the larger stars in my image. I'm retrying some old data on IC434, the Horsehead Nebula and didn't get this issue before hand. I realised it was because previously I used GraXpert denoising AFTER removing the stars from the image, so I'm guessing the added smoothness can affect StarNet. Would you have any idea for a work around? And would you know if it would actually make that much of a difference if I didn't denoise the stars?
    Cheers again for the tutorial, was really quite helpful.

      You ran GraXpert after or before removing the stars? I'm a bit confused because you say it removed the larger stars, but it's supposed to remove all the stars including the larger ones. And, also if you GraXpert before Starnett you're denoising everything including the stars, so that's confusing a bit too. You also mention added smoothing affecting Starnett but that would imply you ran GraXpert before Starnett.
