(2) Confusion as to which is which -- #35815 (Pan) and #38245 Yahsat 1B close together.... SPACETRACK elements not accurate enough to decide which is which. (3) Timing accuracy to be improved - not good enough (yet) for LEO work - still have to determine latency of the camera. (4) Many thanks for the assistance given by Ian Roberts (no relation) who also uses a Canon 650D - (why I choose that particular camera since he has proven it is suitable for satellite work) (5) Severe wind buffeting of telescope so had to reject many images (6) Still more experimenting to do..
