Hallo,

Can someone help me to reduce the red stripes in the background of the pictures.
 I life in a lightpolution area (belgium - the lightspot of europe).
Attached you can find the full size(25% quality) and a zoom of the red stripes.

thanks,

Bart

Hallo

Have a look at this processing example from Alejandro Tombolini
http://pixinsight.com.ar/en/info/processing-examples/19/crux-southern-cross.html
For future images you will need to dither to get rid of this pattern noise. When imaging with a DSLR, move the camera some 12 pixels (in a random manner) between exposures. This will break up the pattern made by faulty pixels, as well as reduce large scale colour noise.

Hope this helps,
