Description

When I first got a telescope, I wanted to look at all the smallest objects in the sky, but since I got narrowband filters I've become interested in the biggest ones. Barnard's loop is over 10 degrees, and the Lambda Orionis Ring (Angelfish Nebula) is around a third of that. Together, they cover most of the constellation Orion. The Orion, Running Man, Flame, & Horsehead Nebulas are all easily identifiable here as well.

I shot this with a 35mm Nikon lens wide open at f 1/1.8, so there is quite a bit of coma outside the central part of the image. I would have stopped down the aperture, but I've discovered that the only way to control the iris on these Nikon lenses without a DSLR body is by jamming something small under the spring loaded aperture control lever before attaching it to the filter wheel. I'm very much open to suggestions for a more precise way of doing this.

In post-processing, R=Ha, G=S+0.5Ha, B=O. After stretching and gradient removal, I've done some adjustments using the Camera Raw filter in Photoshop. I may come back to do another revision later, as I feel like the stretched Ha image had more detail that did not show up here.
