Other Astronomy Clubs

The Astronomical Society of New South Wales:  See how astronomy is done on the bottom (top?) of the Earth. This homepage is a good gateway to many other southern hemisphere astronomy sites, as well.

Chagrin Valley Astronomical Society: Another Cleveland area club to visit. The CVAS is also a member of the Ohio Turnpike Astronomers Association (see below).

Cuyahoga Astronomical Association: Astronomy from the north coast.

Miami Valley Astronomical Society: The group from Dayton is now on the web. They usually have a full schedule of events, so check here if you plan on visiting.

Ohio Turnpike Astronomers Association: The OTAA was formed in 1956 by four astronomy clubs that were located near the Ohio Turnpike. Members of OTAA are astronomy clubs and institutions, whose members are automatically members of OTAA.

Ohio Valley Astronomical Society: The OVAS actually covers three states: Ohio, West Virginia, and Kentucky. The society eagerly welcomes visitors to their meetings and public stargazes.

The Association of Lunar and Planetary Observers.

International Astronomical Union: The Central Bureau for Astronomical Telegrams (CBAT), operated by the International Astronomical Union (IAU), is responsible for the dissemination of information on transient astronomical events via the IAU Circulars (IAUCs). It is available in both a series of postcard-sized announcements and in electronic form.

International Dark-Sky Association: Learn about what you can do to protect the skies from light pollution.

The International Occultation Timing Association: IOTA was established to encourage and facilitate the observation of occultations and eclipses. It provides information and analysis of grazing occultationsof stars by the Moon and predictions for occultations of stars and planets and reports to the members of observations made by others.

Other Interesting Astronomy Sites

The Antique Telescope Society: For collectors of "old glass".

AstroMart: Buy and sell used astro equipment.

Bill and Ted's Excellent Astro-Picture Page: CAS members Bill Kramer and Ted Saker show us what "real world" astrophotography from Ohio can be like.

Comets and Meteor Showers: Everything you ever wanted to know about annual meteor showers, plus late info on comets.

CCD Images by Gregory Terrance: Gregory is one of the best, amateur, CCD imagers around. From his backyard observatory in New York state, he captures stunning deep space and solar system scenes. His work is seen frequently in Astronomy and Sky & Telescope.

Catalogue of Galaxy Images: A nice catalogue from Princeton.

CCD Images of Galaxies: These images are just one part of the University of Oregon's extensive astronomy reference page.

Digitized Sky Survey: This site allows you to download high resolution, b&w, deep-sky photographs for any part of the sky you want. Definitely one of the more useful things on the web.

Solar Eclipse chasing Information about solar and lunar eclipses, how to photography them, what they look like, and what causes them. Large picture gallery of past eclipses.

NASA Liftoff to Space Exploration.

Nine Planets: Try out this multimedia tour of our solar system.

SETI Institue Homepage: SETI, as in "Search for Extra-Terrestrial Intelligence". These guys will probably be the first to know if we're not alone.

SEDS Messier Page: Do a Messier Marathon the easy way...just point and click your way through the list.

Space Telescope Science Institute: This site is usually updated on the same day the major press releases are announced. It's a little busy at times, but well worth it.
