-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 This is not exactly the high precision I eventually hope to be able to render, but I easily spotted Lacrosse 4 at equal elevation to HD 151613 (BD+57 1702, HR 6237, J164517.81+564654.6, PPM 35619) about 17 seconds late compared against Heavens Above data. It was observed at 01:55:12 UTC with local (topocentric) elevation of 20 degrees, three minutes. It passed just to the right of the star, moving at roughly 340 degrees (I think I got this "DIR" angle correct, Mike & Björn). This is the first satellite I've spotted with a better piece of equipment: 150mm f/8 Newtonian with a 32mm Plössl eyepiece. I'm still working on better azimuth annunciation, as the mount I built is primarily to test the overhung-load Y-axis bearing design. With no improvements, I've found a keyhole of about 1/3 degree by 2 degrees directly overhead where I can't point. The field of view (1.346 degrees measured) covers some of the keyhole. This is mostly due to the azimuth bearing not existing in this version of the mount. Pictures of the mount at http://idoru.home.texas.net/mount/y-axis-test/DSC00956.JPG . I am slowly working on tools to generate a motion plan to point a telescope at the orbital plane of a vehicle, either in transit or due east and west of an observer. Now that I know I can point somewhat accurately, the application of the motion plan is more feasible.
