Description

A wide field image containing the galaxy NGC 891 and numerous groups of fainter galaxies.

This was another unguided tracking test for my new 10 Micron GM1000 HPS mount. This was my first proper test of the dual RA/DEC tracking mode that compensates drift due to small polar misalignment. The 15 star pointing model on the mount computer was reporting a 12 arc second polar misalignment error (but not the +/- error in this value).
