Description

Small tightly wound spiral galaxy. Collected exposures over two nights. RGB color camera with IR cut filter. Got more color discrimination than I was expecting, the different colors of the concentric rings of stars is clearly visible. Also visible is a large halo surrounding the galaxy, much larger than the main disk. Manually focused.

The acquisition details above include all exposures. The final image used
82 (of 105) frames x 300s @ Gain 200 @ -10C = 6h 50m exposure time
