Links to Other Amateur Astronomy Sites
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
- Unfortunately, Camera Bug, the Atlanta telescope store, has closed due to the death of the owner, Tim Nix, in December 2014. He will be missed!
- Showcase Photo (the only remaining full-line professional photo supplier in Atlanta; still has darkroom supplies)
- The Camera Doctor (used equipment, repairs, darkroom supplies, in Atlanta)
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). This is a major supplier of tested optical equipment to academia and government. They also sell telescopes and accessories to amateurs, with pre-testing and good user support. Much of what's there is not on the web site. Highly recommended when you need more than the usual level of reliability and expertise.
- 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.
