As others have done I've gone ahead and processed less data than I would have liked because astrodark has now all but gone - something else to blame rather than the usual weather issues! This is

Starnet seems to be the new kid on the block John for star removal, never used it personally but heard good things , lovely image btw .

Thanks David, yes others are commenting on Starnet. I will check it out.

Unfortunately Starnet requires a processor with some features my celeron doesn't have - Oh well I'm getting close to a star removal algorithm I'm pretty happy with. 🙂

I used the stand alone Starnet to remove the stars from my Canes Venatici images.  Not sure if PS or Affinity or other astro SW can add or subtract one image from another but you can in IRIS. Take the input image to Starnet (stars + nebula) and subtract the Starnet output image (only nebula + noise) and that leaves a noise free image of just the stars. Both images (stars only and nebula only) can then be processed seperately and recombined by adding the 2 processed files together to get the final image.

The input file must be a TIF file and it must be stretched, linear data doesn't work.

Are you running 32 bit windows and/or doesn't it support the AVX instructions?

I'm on 64 bit windows, PI fails to find the module and the only applicable reason from the list given in the readme file is that my processor doesn't support AVX. 

 

3. If you do all the installation steps correctly, but PI does not
   ever lists StarNet module in the search window, that most likely
   means that your CPU does not support AVX instructions and the module
   will not work. You can try using Intel Software Development Emulator
   to emulate those, but expect terrible performance. Note that it is
   not the problem of the build or whatever. Support of AVX
   instructions is crucial for a good performance!

Have you tried the stand alone version?

No, didn't see a download for that. I will check it out. Thanks.

Having looked at my README file, I suspect you will the same problem but it's worth a try.  I haven't found anything else so far that can remove stars so effectively.

I've made some progress with my own approach to processing stars which has the benefits of always detecting stars and nothing else. I took a few screen shots to generate the thread so I hope it's OK to include a link to another forum rather than reproduce it here.
