The montage above shows 27 different comets, all imaged during the night of December 20-21, 2004, by Jerry Armstrong in Winston, Georgia, U.S.A., using a MEADE 14" LX200 GPS Schmidt-Cassegrain telescope and a SBIG ST-1001 CCD camera. Exposures varied from 4 minutes to 30 minutes, and each frame is 5.8' x 5.8', with the exception of C/2004 Q2 (Machholz) which is 19.7'x19.7'. Date and time below each image is specified in Universal Time (UT). "The 3/4 moon was present during most of the images", noted Armstrong, and adds: "To my knowledge, this is the most comets imaged in a single night by an amateur astronomer."

Bernd Brinkmann, Germany, comments on January 4, 2005: "Jerrys note is not just correct: I managed to image and do astrometry on 30 comets in the night from 20./21.02.2004 with the 50 cm f/5 Newton reflector and an ST-8 from A33 (Volkssternwarte Kirchheim) where I was a guest observer."
