Hi Jim,


Other users on this list have mentionned that it is important to get up to
date orbital elements (TLEs). It is also important to set the location
correctly. Here you can see a comparison between a picture of the path of
ISS through Cepheus and thetrail from Guide:

you can see that Guide is really very accurate.

> Last night as I was working on my Messier binocular list, I inadvertantly
caught the ISS coming out of the Southwest shortly before 6 PM CST (near
Nashville, TN). I followed it as it slid south of Vega, through Draco and
just north of Polaris before it began to fade and finally disappeard in the
northeast. When I tried to duplicate this with Guide, it shows the ISS (if
I have the right satellite) at -84 degrees Altitude and at an Azimuth of 117
degrees. Can anyone tell me what I may be doing wrong?
