Using StarXTerminator and DBE for nasty gradients
Just found this neat DBE trick posted on YouTube by Adam Block. Video provides an overview of his website/tutorials, but the second half features a nice trick for using DBE with StarXterminator for cleaning up messy gradients, especially the kind I get in my light polluted backyard. The example he shows features a galaxy, so I'm not sure how well it would work when there's a ton of nebulosity, but it's definitely a technique worth adding to your toolkit.
Here's the link on YouTube. https://youtu.be/7ldbGxFi-OM
Enjoy

Re: Using StarXTerminator and DBE for nasty gradients
Thanks Steve,
I did see this video this week and enjoyed seeing this technique. Haven’t tried it yet, but will soon. Actually, I just might start using this method as my normal process of running DBE. It just is so much easier than dodging the stars when placing sample points. Especially when you are dealing with very dense star fields. Very easy and very simple.
I also learned a lesson a bit ago that David @Jockinireland pointed out to me where DBE can be run on starless stretched images to carefully select only dark background sample points to help bring out the dusty areas of an image. That method should work for highly nebulous fields too. Unfortunately, the technique is outlined in his processing example of NGC1333 in his Fundamentals series which can only be viewed if you have purchased the course.
Thanks for posting this. I need to make some notes!

Re: Using StarXTerminator and DBE for nasty gradients
Yeah, Jim. I've used that DBE trick to clean up the background on my starless images and it works well. Overall, I've really got a lot out of Adam's Fundamentals course and have been getting a lot out of the Horizon's lessons too.Juno16 wrote: ↑Sun Feb 26, 2023 8:56 pm Thanks Steve,

Yeah, I guess that it’s time to sign up for Horizons.starfield wrote: ↑Mon Feb 27, 2023 12:23 amYeah, Jim. I've used that DBE trick to clean up the background on my starless images and it works well.

Terrible skies this year so far and it would be nice to have that to look forward to.
