The Horsehead Nebula, B33, was my very first attempt at both an H alpha image and running a script file to control imaging while I slept. This was before I had a temperature compensating focuser and proper image processing software. Still, I got rather lucky in that the temperature was stable. Stars show improper processing but the original FITS files are buried in my basement out of easy reach so I didn't reprocess it. I should take color data for this field but so far that hasn't happened.

This image is reproduced at 1.5" per pixel rather than my usual 1" per pixel.
