Observer: Alex Gibbs, Ken Matesich
Location:Tuscon Mountain Park, Arizona
Optics:8 inch f/10 SCT at prime focus.
Exposure: 1 minute on Fuji SG+ 800, pushed 1 stop.
Hale-Bopp was barely visible for 20 minutes, during twilight, before
it set. In this shot it is only 4.5 degrees above the horizon. North is
to the right and the horizon is below the 5.5 magnitude star (35 Orion).
Image cropped to about .5 by .36 degrees. Average sky color was digitally
subtracted. Since the comet was so low it lost blue and appeared somewhat
orange. Vertical band is from processing or emulsion. Equal gamma correction
on all colors. |
