This color image was collected by David Cornell at the Principia Telescope on August 14, 1999 (UT).   The image was built by software using contributions from exposures in the red:green:blue ranges in the proportions 1:1:2.  Each exposure was taken through the colored filter and lasted four minutes.  A Santa Barbara Instrument Group ST-6 camera took the images and an ST-4 performed telescope autoguiding throughout.
