M15 - a globular cluster in Pegasus

This is a live report from my roof observatory in Germany. I am currently observing the globular cluster M15 in the Pegasus constellation. The photo above has been taken few minutes ago with my FS-102 (f/5.6) telescope at 560 mm focal length. This is a 3 minutes exposure with a ST7XME camera on an unguided JPZ mount under the light polluted skies of BK city. A dark has been substracted. Neither flats nor bias are used.
