Description

Combination of an image of 2007, taken with a C8 and an Artemis 285 camera, and another one taken with an RC8, an h-alpha filter and the same Artemis 285 camera. This camera unfortunatelly has some problems (spots on the ccd surface, noise, cooling). Processing its images is always very problematic. Thanks for looking.
