M53 (NGC 5024), class V, in Coma Berenices

First light of my Artemis Art 4021 CCD camera - many thanks to my friends Liubomir Iliev and Valery Genkov (both of them professional astronomers) for their invaluable help.

FOV with my setup was 7 x 7 arcmin , that is why not entire star cluster was captured in this frame.

1. M53 - Unprocessed single frame

2. Calibrate, combine, histogram, curves

4. Imaging setup - Artemis Art 4021 CCD, ATiK filter wheel, Robo-Focus and SCT focuser 2" on 24" Zeiss Cassegrain @ f/12.5
