OBSOLITE PAGE, PLEASE, DOWNLOAD THE STAR REMOVAL PS ACTION FROM HERE: Star removal PS Action
Many astroimagers had asked me to reveal the method of removing Stars.
It's sometimes very usefull to be able to remove stars from the image.
Some dense Starfields can cover nebula details or the Star bloat can cause
problems with narrowband color mixing.
I have now made a PhotoShop Action for StarRemoval!
NOTE! The primary use is for Nebulae!
It might or might not work with Galaxy images
It has not been tested, so if there is problems or not, please leave a comment.
There might be some large stars, or fracments of them, in the image
after action. They are easy to remove manually.
The action result can vary, depending many factors, Star size, density, etc...
If you like, you cant tweak the parameter in the action for better result.
Or you can use just some part of the action. Be free to experiment.
In my tests I noticed, this works very well to undersampled images >
usuall wide fields one. And there the dence stars are really a problem.
To be sure, that no wanted information is lost, place the starless
image as a layer top of the original and blink.
Then use eraser to restore brighter details.
If you set the transparency, let's say 50%, you can have part of the both worlds.
In Cloudynights CCD-imaging group, there is some feedback of this action.
You can find help in there as well, if you have had some problems.
There has been lots of work to develop this kind of technic.
