Field of View: 1x1 degree.

On the left, a recently taken image of nebulae in the vicinity of Gamma-Cygni is given. A f=300mm tele-objective, fitted with an H-alpha filter (Edmund optics) was used to create this nearly 5x5 degrees field of view. Some distinctly bright and dark nebula are visible of which three were photographed previously in more detail using the 10" Newton (f=1455mm).
