The Horsehead Nebula 10 hours 30 minutes now with cropped and high res versions

I took about 25 hours of data for this one. My mount developed a spike in the PE which meant about 5 or 6 hours was lost. The rest was from an earlier time and it was too rotated to be used.

Software Bisque sent me a new worm for my PMX mount and coupled with the latest firmware I was able to do a very accurate polar alignment as well as an accurate and working PEC. Guiding with the SBIG STi guider and MMOAG tracking was essentially perfect.

10 hours and 30 minutes of Ha LRGB images. AstroPhysics 140 scope (so sharp and wow what a focuser), PMX mount, FLI Proline 16803, Astrodon filters, SBIG STi and MMOAG guiding, Tak 4 inch flattener at my dark site observatory. I had a few nights of excellent seeing so the star sizes on some of the data were very tight.
