Wide-field mosaic image of comet Hale-Bopp, taken on 1997 Jan. 16, with the 2.8/180mm lens, CCD and narrow-band H2O+ filter, centered at 620nm (FWHM=10nm). Two consecutive frames were taken between 5:12 and 5:22UT.
Each frame was exposed for 5 minutes. Morning dawn slightly interfered. Due to viewing geometry, the gas (PA ~345o) and dust tails (PA ~190o) are widely separated and about ~2 deg long. The frame field of view is 3.5x3.3 deg.
North is at the top, East to the left.
