Great comparison Shawn Graxpert is coming on in leaps & bounds lately

[@Astro-George]

Thanks for the update on this great project.

Great video and content 🎉

[@NevadaDesertSkies]

Great comparison, Shawn. Thanks man!

Very interesting, not supprised that NXT is still slightly better as it’s been trained a lot longer, but as GraXpert is free, then that’s great news for people who don’t have the funds for the Xterminator plugins…👍🏻

[@Jamesee777]

Interesting! It's now a head to head race. I hope that makes rc astro improve noisexterminator sooner, rather than later!

Would love to see GraXpert star removal tool. Thx for the video

[@qx3V45p]

Works MUCH better than previous version and hard to see much difference between BXT with the few nebula images I compared. Very nice.

[@JohnMcGFrance]

Sadly, at the moment there is a known issue for some Windows 10 users and it doesn’t work. Graxpert say turn off hardware acceleration but if it won’t load you can’t turn it off. Guess I’m stuck on the older version until they release a fix. Fingers crossed it comes soon. Very useful video as usual. Thank you.

[@davenewbury198]

Thanks Shawn. Not sure about others experience but it seems you have to run the Graxpert local install and use the 2.0.0 denoise at least once (to force it to download the ai model) before the 2.0.0 model would show up in PixInsight.

[@VisibledarkAstro]

Thanks Dave. Yes that would be correct. I believe that's what I did. Thanks for the comment.

[@danbartlett7923]

Hi Shawn, I noticed you applied 0.10 sharpening in the NoiseXterminator process (as you had done in the previous video}. I do all my sharpening outside of denoising. It would be interesting to compare both denoising methods without the sharpening applied. I realize 10% sharpening isn't much, but its more than 0%. Thanks for your videos!

How do the details in the galaxy compare between the two (before/after denoise)? Sometimes the denoise process can have an affect on details in the galaxy as well.

[@nikaxstrophotography]

Good to see Graxpert coming along with noise reduction, however it is so slow compared to NoiseX and NoiseX still is a better product in most circumstances.

No SNR script. I'm not surprised. I've yet to have a tutorial from youtube work the 1st time in PI..

Hi ... I have an older version of GraXpert on my Win10 computer .... and I want to update to the latest AI version. I have seen that most people say that I need to delete the older version first .... but how??? I can't find any guidance on the GraXpert web site ... or anywhere else for that matter :-( GraXpert does not show up in the Control Panel/Programs list .... but I have found all sorts of files obviously linked to GraXpert on my C Drive ..... but I don't know if I should just delete all of these one by one .... or if there is a much better way of removing GraXpert before installing the latest version. Is anybody able to give me some advice about this? Mike

[@bobbryant4410]

I installed GraXpert v 3.0.2. GraXpert executes from windows but when I try to run it from PixInsight it get cx_Freeze: python error in main script. If I remove GraXpert from PixInsight the Process and Script links remain in PI.

[@VisibledarkAstro]

Did you uninstall the previous version? And install the new 3.0.2 version. I had to do that with ver 3 and ver 3.0.1 - try it and see. Also make sure the repository urls scripts are up to date with the latest.

@@VisibledarkAstro I got a reply from DeepSkyForge that fixed the problem. Sorry for delay, I was on travel. This is a known issue in GraXpert. To fix that, you have to: manually remove old AI models (see locations below), Run GraXpert application and process an image (background extraction and denoising) to force AI model download. My Quick Start Guide gives location of AI models but in short: Windows: C:\Users\AppData\Local\GraXpert\GraXpert\ai-models\ macOS: /Users//Library/Application Support/GraXpert/ai-models/ Linux: /home//.local/share/GraXpert/ai-models/
