Comet Hyakutake Develops Two Tails. This photo is the first to show the turn-on of the ion tail. It is a reproduction of a 15-min CCD exposure obtained with the Danish 1.54-m telescope and the DFOSC multimode instrument (2k x 2k pix CCD). An R-filtre was used. The field measures 10.4 x 10.4 arcmin; the scale is 0.39 arcsec/pix; North is up and East is to the left.

Sum of 2 X 300 sec exposures. North is up in this 23' X 15' field, which has been scaled down here. False colour palette has been applied to show inner and outer detail in the coma and tail. The the coma is approximately 15' diameter, when viewed with a higher contrast setting than shown here. Taken with a 25cm f/4.1 Newtonian and HI-SIS 22 CCD.
