Are you really processing an 8-bit image?Here is the original best regard Kjell-Arne View attachment 15872
Are you removing stars before or after stretching?I found AI11 to be too aggressive when it comes to removal of structures as some nebulosity is removed as well and appears in the star image.
This happened for a Veil nebula and a Jellyfish nebula example I ran SXT on.
I will test more and report back with screenshots of before and after for both AI versions.
What can be said though: The noise estimation of AI11 is very good!
No it is a Jpg compressedAre you really processing an 8-bit image?
Wich is 8-bit, isn't it?No it is a Jpg compressed
Are you removing stars before or after stretching?
Thanks for posting the comparison.I did some testing with AI11, AI11 lite, and AI11 lite without noise-matching
top left is original file, M45 is not stretched, the other two are stretched.
top right is AI11
bottom left is AI11 lite (first version)
bottom right is AI11 lite without noise-matching
In my case the process took 24 secs, 16 secs and 15 secs respectively, so not too much gain without noise-matching.
This was tested with a GTX1660 Super 6GB, as my RTX3050 4GB cannot run SXT with AI11.
Hi,Thanks for posting the comparison.
Will the 3050 not even run AI 11 lite? That's surprising. Do you have the zlibwapi.dll file installed on that machine?
Yes, I understand your point. Maybe provide an alternate download link for the .pb file. But that could also be confusing for some users.It's not a problem to provide all three versions of the AI... they're trivial to generate from the base model. It just makes for large downloads and potential confusion for users. I could split them into separate packages so folks could choose which to download, but my impression is that most don't look at what the updates are to pick and choose, or even read the release notes... they just click the button. ?

I was looking at the specs of the RTX 2060 mobile and it seems to be superior in almost every spec to the RTX 3050 mobile. And is also far superior to the GTX 1660 Super. That makes me wonder if the excessive processing time RFtinkerer is noticing is caused by the GPU or not. The RTX 2060 mobile should be able to run the AI 11 full version easily. Maybe has to do with the interaction of the CUDA, CUDNN and tensorflow versions. But I'm no expert.

Here's the original thread where I introduced this technique: https://pixinsight.com/forum/index....recombining-stars-with-starless-images.18602/Russell, I must have missed it when the checkbox for Unscreen Stars was explained. What does this do?
