Observers: Dave Tholen, Richard Wainscoat
Location: University of Hawaii
Date: September 1, 1995 UT

North is at the top, and east is at the left. September 01, 1995 (UT) true-color image from obtained from separate B (blue), V (green) and R (red) exposures from the University of Hawaii's 2.2-meter telescope. The observations were performed by Dave Tholen, and the images were processed and combined into this color composite by Richard Wainscoat. Each exposure was 30 seconds, and the CCD was read out very quickly. Only 57 seconds separate the start of each exposure, meaning that since the comet was moving rather slowly, the movement of the comet was very small. This meant that the stars could be well aligned to make a true-color composite. This image has been color calibrated so that the Sun would appear white. The comet's coma is slightly redder than the Sun; many of the background stars are redder than the Sun. The field shown is 105 x 105 arcseconds, and the seeing is approximately 1 arcsecond.
