Russel Croman (GradientXterminator) has just released a new photoshop plug in to remove stars - StarXterminator

 

StarXTerminator (rc-astro.com)

 

On a very quick runthrough I am highly impressed.

 

i took the same image

removed stars in Pixinsight with Starnet++ to get this - some quite bad artefacts

Took the same tiff image into photoshop used Star exterminator to get this much improved version

One of my problems with Starnet++ has always been the matrix artefact where bright stars were removed, like this

with starXterminator that is just not an issue (the sales pitch does reference this specific issue)

I have a lot more trialling to do with it but it sure looks promising.

 

See what you think.

Starnet does leave some quite bad artefacts at times. The secret is not to fully stretch your image before applying Starnet in Pixinsight. The Star exterminator seems to do a great job, can you remove the stars and recombine them with this plugin?

Hi Brian, honestly I've tried all that with starnet but always end up spending ages dealing with the blotches. This new plugin seems very impressive. 

 

Yes, there is a detailed simple procedure to put the stars back in the linked page.

Only one problem, I don't use Photoshop for my images and converting to Tiff, then bringing them back into Pixinsight to finish processing is a bit of a pain. Once I convert an image into Tiff, I lose a lot of the image properties associated with the xisf file.

Oh well, not for you either then i guess. I already juggle between PI and PS and I dont even know what lmage properties are associated with the xisf or what knowing them would allow me to do better. 😆So for me this could be a fantastic addition.

It would be nice if this guy could make the same plugin for PI, because Starnet was launched as a bit of a gimmick IMO, and has never improved since it's first release.

I've just tried this in Affinity Photo. Seems to work very well. The below are fully processed image of M90 from earlier this year, a starless version using StarX and a stars only version by duplicating the original image as a layer, then using subtract blend mode on the StarX layer.

M90_RGB_IP_AFP.thumb.jpg.245f399481654450cc3bd729cedf77c1.jpgM90_RGB_IP_StarX.thumb.jpg.aff16bff08f8002d634b10e48669273a.jpg702539024_M90_RGB_IP_StarX(starsonly).thumb.jpg.d14707d82484805b06580ffecef8e607.jpg

Using StarX on the fully processed image isn't what one would normally do, but I wanted to just see if it works. I'm sure that this new tool will be a great addition to my DSO processing workflow. It would probably have made processing that horrible saturated star at the top left much easier to handle.
