      Description

      10h32m on M45 (240s x 158, iso800, f/4). bortle red/white zone, CLS filter.

      thanks to ferran's image [here](http://astrobin.com/8179) i was able to compute a proper background model for this reprocessed image. because of the CLS filter everything is blue to begin with and it would have been impossible to tell where to try to sample the background for gradient removal.
