    I am new to Aurora/Luminar (bought both), but I think tuts about taking sky photos are mass in internet. The question is actually:How to post-process these photos with your software? wich one is reccomended (Aurora or Luminar)? Should exist Nightsky Presets?
    It would be nice if you have a video.
    Maybe some day; thanks anyway!
    Meanwhile Im trying to enhance my night sky photos with Rawtherapee as reference...

    Hi!

    The processing steps will depend largely on what you captured - different cameras, lenses, and settings can vary greatly, especially with astrophotography.

    In my own night sky work I made use of the Tone (or RAW Develop/Develop), Clarity, Saturation/Vibrance, and Denoise.

    If you'd like you can post an example of one of your images and I'll be glad to make suggestions on filters to try.

    This article on our blog also has some post processing suggestions: https://skylum.com/how-to/how-to-take-pictures-of-stars

    I think it would be a very nice idea to have such sky tuts with LUMINAR/AURORA, just because the main pic in SKYLUM is a stars sky.

    If you think I shold post you here the other two photos, let me know.

    Thanks for your time!

    Hi E Lopez,

    It looks like you certainly improved the image with Luminar (comparing the one posted above, and then checking out the link to 500px).

    You may also want to try a Tungsten white balance (or experiment with different white balance settings), increasing the vibrance a bit, and also increasing contrast.

    Let me know what you think.
