First, I am surprised it could be so much off! Stable orbit, not maneuvering? Second, a satellite tracking telescope control program or firmware should be able to cope with long advance/delay times. But LXsat=SatelliteTracker computes the RA/Dec track for -0/+0 and leaps along the SAME track when time is adjusted, and I suspect that Meade AutoStar does the same (and is inaccurate anyway!). Third, for a binocular object I usually copy the TLE and adjust the Mean Anomaly (line 2,44-51) in steps of ~30 degreees (less for a HEO) and predict them all in one map (SkyMap). (Other programs may need the catalog numbers to be different.) Fourth, for telescopic search, I use the map (or calculation) to find a part of the tracks where the displacement in RA (or Dec) with time matches a slew speed in my scope. E.g. where RA changes by -3 min/min I choose slew speed 4x, and keep the W slew pressed while searching. /Björn ----- Original Message ----- From: "Brad Young" No 28054 -7/+11 minutes.
