A couple of "movies" put together from images I shot during this morning's approach of minor planet 2010 TD54. Paramount ME, Celestron C-14 operating at f/5.5, SBIG ST-10 binned 3x3 with clear filter. Field of view is about 18x26 arc minutes. The target was rotating quickly during both sequences which is "reflected" (pun intended) by its rapidly changing brightness. Mount set to allow the target to pass through the field of view. 16 five second exposures shot between 08:51:51 and 08:54:04 UTC. http://users.wirelessbeehive.com/~paw/temp/2010td54-01.gif Mount set to nearly follow the target. 23 five second exposures shot between 09:01:27 and 09:04:39 UTC. http://users.wirelessbeehive.com/~paw/temp/2010td54-02.gif patrick
