Barnard's Loop and the Orion Complex
in Hydrogen-alpha Light
Using the Mandel Wide Field Imaging Adapter
Published in Sky&Telescope Magazine

This CCD image was taken with an SBIG ST8E camera and a 50mm Nikkor camera lens at f/4 using the Mandel Wide Field Imaging Adapter.  It is the combination of  15, 10-minute exposures with an H-a filter.  Image acquisition and processing were done with Maxim and Photoshop.

Barnard's Loop is thought to be a supernova remnant.  This is the most extensive image I have ever seen of this area and shows the huge size of the Orion nebulosity as well as the Loop.
