Crescent Nebula (SH2-105)

First attempt at imaging since the new floor was completed in the Observatory.

Focused by hand as the electric focuser is currently not working – hence not quite in focus.

This is a 7×5 minute stacked image taken through a Hydrogen Alpha filter. Telescope being a Takahashi Epsilon 180ED at f/2.8. (A brute to manually focus!) Camera; Atik 4021, cooled to -27 degrees. Guiding by PHD and all sitting on a modded EQ6.

 

Also an image of IC1318, the diffuse Hydrogen Alpha emission nebula surrounding ‘Sadr’ (upper right), the 2.2 mag star at the ‘heart’ of Cygnus the Swan.
