AstroSharp is back!
After a few years on the back burner, I've been updating AstroSharp with a faster backend, a much more usable Windows application, and—most importantly—a version that now runs directly inside Siril.
In this video I'll show:
What has changed since the original release
The new standalone Windows version
How to install AstroSharp in Siril
How to choose PSF values
The new preview mode
Performance improvements (processing is now dramatically faster)
New blending controls and workflow improvements
AstroSharp is still completely free.
