North America Nebula

Rising early on Saturday morning to see the last of Comet Panstarrs and M31, I decided to shoot the North America Nebula (NGC7000) before the comet rose high enough to photograph.

It's a large nebula complex spanning approximately 2 degrees x 2 degrees.  Noting that the moon is approximately half degree in diameter it shows how large this nebula complex is.

The following photo was taken using my William Optics 80mm diameter apochromatic telescope with a 0.8x reducer, resulting in an effective focal length of 436mm at f/5.

I made fairly extensive use of multi-layer processing with the high-pass filter at various strengths, blended into the main image to help enhance certain features of the nebula and make it more 3-dimensional.
