Recently the Dwarflab app got a very interesting update in the beta stream. But not for telescope control - no this is in the album side. It now has options to upload your images to temporary AWS nodes for automated reprocessing. Star de-trailing, full star removal, and advanced denoising.
Most of these can be handled by well-known and publicly available neural networks, which is probably what these tiny AWS nodes are running.
The real fun, though, begins when you combine the results.
In this shot, I have taken the starless version, and added to it a heavily darkened an contrasted denoised version. This has the effect of reducing the stars, while maintaining the details of the nebula.
A bit of deblurring and sharpening, and this is the result.
