    I'll observe some of the older payloads such as Telstar 1 and Tiros 1 and 
    some of the dimmer objects such as Celestis 2 with a 6" DOB.   I'll also get 
    a longer look at Superbird A and some other geosync flashers.   The haze at 
    my location can be brutal in the summer making binocular observing impossible 
    for all but the brightest objects.  
    When plotting passes for telescope observing, I just tweak some of the 
    settings on Rob Matson's Skymap program:
    From the Star Catalogue Menu:
    Star Magnitude Range = -2 to 14
    From the Map Attributes Menu:
    Map Type = Stereographic
    Grid spacing - Az = 1 deg, El = 1 deg
    Vertical field of view = 5, 7, or 10 deg
    Satellite Information:
    Trajectory resolution = 1 sec
    Tick Mark resolution = 1 sec (60 for geosyncs)
    Time Tag resolution = 5 or 10 seconds (600 for geosyncs)
    Track Coords = Equatorial (A *must* for this type of obs)
    After you autolocate and use "Automatic Pointing" for your pass, just plot 
    the pass and move the plot to an easy to find star near the pass and star-hop 
    to a location in your FOV.  Using a Celestron Ultima 35mm eyepiece I have a 
    1.4 deg FOV which seems to be more than enough for most obs.
