Title: Star alignment issue
Post by: FunTomas on 2017 June 25 03:06:15
To this time I never have problem with image registration. Now I have set of comet Johnson images, that I cannot register using star registration module. I have used default settings. Later tried to change log sensitivity or other parameters. Still the same result. Sample images are stored on endor file server.

Comet Johnson sample files (http://endor.uv.es/files/data/public/b53c34.php?dl=true)

Please help, if anybody knows.

The problem with these frames is high noise and hot pixel artifacts. Increase the noise reduction parameter (Star Detection section) to 3 and the images register without problems with default parameters.

Juan, thank You very much. Next time I will try this parameter too.
