Thanks to all who have commented on planar searches; perhaps I should clarify. When searching, I will use a non-guided Dobsonian or 12x60 binoculars. I often do just "sit" on the star the sat should pass. Recently I have started trying to guess displacement from that star based on time early or late (eg 1 degree west of star for about 4 minutes early - pretty close since I am at 36N latitude. If this is an approach to a planar search, then I think I get it. If I'm missing something, please let me know.
