Michael Covington's Links to Other Astronomy Sites
The World Wide Web doesn't work the way it used to,
and neither does this page.
This page was created in 1999 to support Astrophotography for the Amateur. At one time it contained a huge number of links, but it was not practical for me to keep them updated. In those days we relied on "link pages" and "link exchanges" to find interesting material; we didn't have good search engines and Wikipedia.
Nowadays, search engines are constantly indexing the Web and we don't have to do this manually. So I've trimmed this page down to a ghost of its former self.
I am not looking for link exchanges. If you want to promote a commercial business via this web site, please see my advertising policy. Rest assured that nothing you see here is a paid advertisement unless it is clearly marked as such.
This page is not about astronomy as science; it is about how to use telescopes and astrophotographic equipment. For general information about astronomy, please see Wikipedia, Astronomy Magazine, Sky and Telescope Magazine, and Spaceweather.
Here are a few links of general or local interest:
Especially for North Georgia
- Clear Sky Chart for University of Georgia Observatory
- Sky chart for Northeast Georgia, showing the sky right now
- Sunrise/sunset and Moonrise/moonset for Athens, Georgia
- Sunrise/sunset and Moonrise/moonset for Mansfield (CEWMA) site
- Visible satellites for Athens, Georgia
- Visible satellites for Mansfield (CEWMA) site
- High-resolution visible cloud map (daylight hours only)
- Atlanta Astronomy Club
- Deerlick Astronomy Village
- The University of Georgia Observatory
- Camera Bug — major telescope dealer in Atlanta, a good source of equipment, literature, and advice. (Has recently moved to the other end of the shopping center; they're not gone, just relocated!)
- Showcase Photo (the only remaining full-line professional photo supplier in Atlanta; still has darkroom supplies)
Where to buy telescopes and other equipment
- Orion Telescopes and Binoculars (mainly their own brand of telescopes and accessories, which are good; very good place to start if you're a beginner; very informative catalogue)
- Astronomics (leading full-line dealer selling all brands, recommended for the more experienced observer; has informative literature for beginners too)
- Oceanside Photo and Telescope (photographically oriented, especially digital SLRs for astronomy; located near San Diego; highly recommended)
- Company Seven (near Washington, D.C.; specializes in quality and good service; tests telescopes before shipment)
- Large-volume discount camera dealers:
- Adorama (low prices, wide selection; New York discount dealer with staff knowledgeable about astronomy)
- B&H Photo (low prices, wide selection of everything photographic; mail order and New York store)
- Samy's Camera (the B&H of the west, in Los Angeles)
- KEH Camera Brokers (reliable used cameras; nationally prominent dealer in Atlanta, mail-order only)
- Note: B&H, Adorama, Samy's, and KEH usually have the lowest North American prices on photographic equipment. Other reliable dealers' prices will be similar.
Vendors who advertise much lower prices are often unreliable. Be especially wary of "bait and switch" tactics ("you don't really want that, it's no good, here's something better made by a different company"). When in doubt, check Google Groups to find discussions of particular vendors, but remember that bad experiences are much more likely to be reported than good ones; consider carefully whether each complaint is reasonable.
- My DSLR page (Canon EOS, Digital Rebel, Nikon D70, etc.)
- Improving the classic LX200 power inlet circuit (how to give it true chassis ground, reverse polarity protection, and no need for an external fuse)
- Drift method polar alignment reference card (for people familiar with the method, who want a brief memory aid)
- My notes on polar-aligning an LX200 by iterating on Polaris and one star
Note: This was an attempt to work out the geometry of something in Meade's manual. I do not actually recommend aligning this way. Instead:
(1) Make sure the 90 degree mark on your dec. circle is accurate;
(2) With computer turned off, point telescope to 90 degrees dec. and align wedge or mount with finderscope using this chart;
(3) Refine by the drift method as described in How to Use a Computerized Telescope.
