Tony Hoffman's AstroWeb

The Moon amid the Pleiades star cluster on
the evening of April 1, 2006, as seen from
the Brooklyn Heights Promenade, which overlooks
lower Manhattan. I used a Canon Digital Rebel
with a 100mm lens. (c) Tony Hoffman

I have been an amateur astronomer since 1972. I am a director of the Amateur Astronomers Association of New York, and write a monthly column called "What's Up" for its newsletter, Eyepiece. Areas of particular interest to me include observing comets, planets, asteroids, novae, the Space Shuttle, ISS, and other spacecraft, and deep-sky objects (galaxies, star clusters, and nebulae), as well as atmospheric phenomena such as solar halos, sundogs, and the like. On these pages, I will provide accounts of my observations (naked-eye, binocular, and telescopic) of comets, meteor showers, and other objects and celestial events, my discovery of comets in online images taken by the SOHO (Solar and Heliospheric Observatory) spacecraft and of near-Earth asteroids as a Spacewatch FMO Project reviewer, and articles and reviews of general interest about astronomy and space travel (including parts of my "What's Up" columns), as well as astrophotographs, mostly taken with a Canon Digital Rebel.
