I think most people know that other auto gradient correction tools can try to correct small scale structure that isn't gradient, but maybe you don't know how prevalent that actually is! I also feel DBE if you spend the time meticulously placing points can get you the superior result.

Wouldn't it be nice if there was a way to have those points created automatically? Maybe also have a means to exclude dark nebula so they don't become part of the gradient correction model??? That is exactly why I created this script!

Get the newest gradient correction tool ADBE and put it in your toolbelt to use!

  • Awesome! I saw this script about 10 mins ago get added to my PI update and I was thinking "there has to be a video or something associated with this." Just got this video update 2 mins ago, so crisis averted. In all seriousness, thank you. Auto-DBE is incredible. This is a great new tool for us amateurs. I love how you've identified these extracted backgrounds that are taking structures with them. You've given me ANOTHER reason to go back re-do all my images. The comparison to Graxpert was shocking. Your scripts are killing it.

    I have to try this on old data and compare! I love the fact that it’s not a blackbox and we can look ‘under the hood.’ Amazing work. Thank you so much.
  • After watching the video yesterday I spent the evening extracting backgrounds with Graxpert and your script to compare. Your script does an excellent job is my conclusion. Thanks for doing this, it is so helpful!
  • @simonpepper5053
    Thanks Franklin you are winning at script writing currently! Will definitely be adding this! 👏
  • @philleng480
    Totally agree re Graxpert stripping out structure. Ran it on Rho Ophiucus and the extracted background looked like .... Rho Ophiucus! Same with the LMC. I always liked the DBE in APT, but that is a slow and artistic process. So this inside Pi is a great step forward. A huge thanks for this.
  • @KakuSarma
    You are doing real great job to help astrophotographers like us. Highly appreciate you for making our life easier. A big thumbs up.
  • @jd.1184
    This is an awesome contribution to the Pixinsight DBE workflow!
  • @FPVA71
    Yes I have gone back to DBE after using GraxPert and Graident Correction, but I will now be using your new AutoDBE, thanks mate
  • @galactus012345
    Impressive again. I always struggle with gradient in my polluted zone. Thx
  • @CuivTheLazyGeek
    Looks amazing! Will need to test it out :) In particular being able to check the DBE points is great. To be fair to GXP, while its creators recommend smoothing=0, from my tests I've recommended from the beginning to set it to 1 in most cases (unless there are sharp gradients such as Newt reflections in the image), it's far, far more respectful of structures at smoothing 1! By the way I used your continuum extraction script as well as your statistical script on a live stream yesterday, everything worked amazing!
  • @astrofromhome
    That's amazing Franklin! I need to try the script out! I always had the impression that Graxpert is removing some information from nebulae and galaxies but I was unable to find out if my feeling is correct. Therefore I switched over to use the PI Gradient Correction tool more often. The Gradient Correction tool seems to remove less structure from what I could see on the screen. Any step towards affecting the gradient itself only is very much welcome when shooting from a strongly light polluted area.
  • You’re an excellent presenter….thank you for all that you do😊
  • @zaphus
    Fantastic - I was kind of expecting this, it seemed a logical step from 'find my background', but the results look even better than I expected.
  • @stavros57
    Another great script Frank. I find I at least run a DBE on most images to compare with Graxpert and more often than not use the DBE version (Does take time as you say). I use all your scripts and have no doubt I will be using this one as well
  • @AstroIsland
    Absolutely fantastic work again Frank. The speed you’re going at you may end up building your own version of Pixinsight altogether. Can’t wait to see what’s next. In the meantime I’ve got some images to ADBE now 😉 Keep up the great work!
  • @miketronix
    I was mostly using DBE cause with AI I wasn’t happy. Now yours is a super duper script! Will install it tonight! thank you a million!
  • @Astro_Shed
    Wow, superb and I have had my doubts about these latest gradient tools, and you have proved my theories….nice new tool..👍🏻
  • @astromatz
    Great! It's always good to have alternatives. Thanks a lot for this interesting script and for your time developing those very helpful tools.
  • @emuhead
    Even yet more brilliant work, saving us all time & saving data in our images too. Huge thankyou!
  • @user-sv9xi1sr6k
    Blown away by all your scripts! They have become an essential part of my PI workflow! Thank you!
