Best shot I got out of a couple of dozen.
Prime focus, 90mm objective, 1250mm f.l., f/14, ISO 800, 1/10th of sec. C90 Mak lens, EOS 7D camera.
Kenko SkyMemo S equatorial tracking drive & accompanying wedge and tripod, roughly hand-aligned using a level and compass (no line of sight to Polaris, and set up before dark, anyway). Vibration is a big problem at this f.l. Most of my shots, even with a 1/10th second exposure, were smeared.
