Description

This was an unusual image because of the many difficulties I had with it.  I imaged it as something to shoot while waiting for my planned target to get into position and only shot 20 frames, of which I tossed out 2.  I had moved the camera from prime in my C11 to the front, with Hyperstar.  Refocusing was a chore so I pumped up the gain as far as it would go so I could at least see the donuts.  Of course I forgot to set it back.  I realized my mistake when I went to calibrate and stack in Pixinsight and my darks wouldn't work.  I reshot the darks but of course noise control  was a problem.  Processing took a bit.  Known as the Boogeyman Nebula, the dark nebula is framed by the red background nebula in an area close to Barnard's Loop in Orion.  It's relatively close in galactic terms, being only about 500 light years away.
