Re: [APML] asteroid photography ***Urgent***

Marie,

        You can take many guided exposures and then use software to compare them
so as to identify differences (which will hopefully be your asteroid(s) of
interest) between the images or take a long guided exposure and look for small
streaks which represent the differential rate of movement of the asteroid(s) of
interest relative to the background stars.

        I would NOT use a tripod and long exposures since you will get star
trails wbich will make it virtually impossible to identify trails due to an
asteroid.

        One of the best online references is the excellent article by Dennis di
Cicco (S&T Senior Editor) which you can browse by going to
http://www.skypub.com/sights/asteroids/hunting.html ... something I have been
meaning to do for some time is to get a reprint of this article which was
published in S&T.

        Good luck with the project tomorrow!

Anthony.
