That expression is the one to use to generate the stars-only image from the original and starless images. To re-screen the stars back onto the (perhaps further processed) starless image, it is:~((~starless)*(~stars))or, since op_screen() has been added to PixelMath:combine(starless, ...
If using PixelMath to combine starless and stars image, should I leave it on? P pfile Well-known member Oct 10, 2024 #2 no, you probably don't want rescaling on. Reactions: astronoob fredvanner Well-known member Oct 10, 2024 #3 This is not completely obvious. If you are sim...
This gives me total control over how the stars will look in the final image. Then completely process(stretch, contrast/saturation/colours, etc) the starless nebula as needed. then I use pixelmath to put the stars back. Check out my astrobin linked in my signature to see what the end ...

For this image I did a run of RGB subs so I could extract the stars at add them to a starless HOORGB image. Using Astro Pixel Processor I integrated the OSC UV-IR subs. Then using the APP algorithms I extract Ha from the L-enhance subs, then Oiii from the same subs. In PI I ...
If I add the stars back in with PI, I apply NoiseX after doing that. But often I save the stars and starless images separately and combine them in Photoshop using layers. In that case I may apply NoiseX to the starless image in PI, but often wait and apply it in PS (since it's ...
You actually need to rename your stars image to "starsonly" for the script to work. Code: ~(~$T*~starsonly) Apply the script to the starless image ($T). For what its worth, I apply SXT to the linear image right after PCC and re-combine the two processed, stretched images ...
It uses StarNetV2 or StarXTerminator (whatever you have installed) to remove the stars and then just combines the starless image with itself using a luminance mask and adds the stars back. StarXTerminator sometimes seems to forget the AI model - in such cases the script might fail and you ...
The first (and best) is to remove the stars prior to stretching. This approach has the added flexibility of being able to perform different stretches on the stars and starless images. If you don't want to back up that far in an ongoing workflow, the second possibility i...
