Comet Hale-Bopp

Until recently astrophotography demanded the use of film. Today's DSLRs have sufficient control of high ISO noise so it's possible to take a shot like this and have it work  When Comet Hale-Bopp (named after two discoverers who spotted the comet independently) reached perihelion in 1997 I reached for my trusty Nikon F2 and loaded it with Fujifilm 400 print film.  The stars are not blurred through this five minute exposure because I mounted the camera atop an aligned telescope drive. Astronomers call the practice Piggyback photography. On this one night in late spring of '97 I was able to get to a dark-sky site in Oriental, CA.  I got half dozen useful exposures of this body that was called The Great Comet of 97.  It remains in my memory as the brightest comet of my life.  It stayed visible for much of 97 before it rounded the sun and vanished into the southern skies. I used this image for the cover of my music CD, OUT OF THIS WORLD Art's CD on Youtube
