Four asteroids

Peter Meadows

A stacked set of six images obtained on 16 November 2009 with the Sierra Stars 61-cm f/10 Cassegrain telescope in the Sierra Mountains, California (Observatory Code G68). Each image had an exposure time of 2 min, with 10 min between images. The image centre is at RA 03h 08m 47s and Dec +21° 13' 52" (in Aries), and the field is approximately 20 arcmin. The movement of four asteroids of 17th and 18th magnitude is easily seen.
