Noise Reduction in Deep Sky Images

[Obelisk]

Just tried creating a profile from the dark frame taken whilst imaging NGC1893 (lots of stars and nebulosity). Cleaned up fairly well. Probably not the way to go but worth a punt.

Incidentally GREYCstoration within Nebulosity works well. However, it is a lot slower than Neat especially if you up the number of iterations and the computation precision.
I understand it is now a GIMP and Photoshop plugin.

Hi Colin

No, they also have a stand alone version. No need for Gimp, Photoshop or whatever then.
