An hour after sunset, under a superbly clear sky, the ISS made a stunning, 69 degree elevation pass, which I tried to track with my 10" Meade LXD55 Schmidt/Newtonian, after downloading the freshest McCants TLE into the telescope's Autostar controller (I verified that it was identical to the latest OIG TLE). As with a lower elevation pass several days ago, Autostar indicated an "AOS" about a minute later than the rise time given in my NASA J-Pass email report. The telescope basically seemed to follow the path of the ISS, but delayed by that amount of time- which is to say, it didn't work! I had my latitude/longitude entered into the scope accurate to better than 100 meters, and the time accurate to better than 1 second of atomic time, and apparently the scope was well aligned with the NCP. I may have another chance Monday, in which case I'm inclined to fudge the telescope time by the difference in rise time computed by Autostar & NASA. Any other suggestions? ----------------------------------------------------------------- To unsubscribe from SeeSat-L, send a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@satobs.org List archived at http://www.satobs.org/seesat/seesatindex.html
