Barnard's Loop, Horsehead and Messier 42 in Hydrogen Alpha
Ive seen some lovely images of Orion taken with a hydrogen alpha 656.4nm filter on a wide angle camera. Im still very much learning how to do this but this was taken as follows:
Modified Canon 60D with Astronomik clip-in 12nm Hydrogen alpha filter. Sigma 50mm f/1.4 Arts at f/1.6.
52 x 2 minute subs @ ISO400
AstroTrac tt320x AG Mount with PoleMaster polar alignment
BackyardEOS for focusing and acquisition control.
PixInsight and Photoshop CC processing.
100 x dark frames
150 x bias frames
Camera sensor temperature 12-16c.
