Another try at Barnard's Loop in Orion WITH a guide camera!

Another clear evening (that's two in a row!) Out to the obs for some more tests with a new guide camera my wife got me for Christmas, an Astromania SGCMOS through Amazon. First time to really use it and WOW!!  Long exposures (6 plus minutes) with no star trailing... and I haven't found the upper limit of length of exposure yet!

This is a SINGLE image using an old Canon 40D camera with some post processing using GIMP, Luminar, and Preview.

Wide field image of the region of the constellation Orion. Showing Barnard's Loop, the Great Orion Nebula, the Flame nebula, the Horsehead nebula and a touch of the Wizard's nebula (far right).

Info: Canon 40D camera (NOT modified), ISO 200, 50mm lens set at f/4, 6 minute exposure, piggy-backed on a Meade LX200GPS 8" equatorially mounted scope, guide scope 50mm, guide camera is an Astromania SGCMOS (from Amazon).
