Subject: Photometry on an asteroid 790 Pretoria

July 19th occultation of the subject asteroid has resulted in the discovery of a new binary star.  IOTA has asked for photometry of the asteroid to aid them in determining a period of rotation.  I have an occultation at 9:30 PM local, and the asteroid rises at about 10:30 PM.  So, eager to play with the new DMK21 and Astro-IIDC this seems like a good opportunity to reconfigure the scope for imaging Jupiter, and then switch over and capture some video of the asteroid for Photometry.

The question in my mind is, how much video should I capture?  Should it be continuous for a few minutes, or a series of frames periodically?

All suggestions welcome.
