LINKS TO LEARN MORE

These are our top picks for recommended websites for each of the topics covered by The Backyard Astronomer's Guide. Explore these links to build your own astronomy "favorites" or "bookmarks" list.

We also list the same links to recommended websites under each Chapter, but this page compiles the complete Links collection in one place.
Special Notes About the Links:

- For manufacturers, we have listed only phone numbers, the business location by U.S. state, Canadian province or other country (i.e. UK and Australia), and website addresses. For international companies, we provide U.S. websites.

- We have not provided postal addresses of companies, under the assumption that most readers will want to get information first from a website, using "snail-mail" only as a last resort. FAX numbers, postal addresses, and street locations of manufacturing plants and stores can always be obtained from the company's web page or via an e-mail inquiry.

- Within each product category, companies are listed in alphabetical order.

- We have listed only companies that advertise into the North American market and that maintain a North American addresses, not overseas companies that sell primarily to European, the Orient, or other markets.

- The only dealers and stores listed are those who may have exclusive North American license to certain brands of telescopes. Major manufacturers have links on their websites to their network of dealers.

- In all cases, these listings are provided for the convenience of readers of The Backyard Astronomer's Guide and do not necessarily imply an endorsement by the authors of the companies or their products.

- Second-Hand Telescopes and Equipment
- Telescope User-Group Sites
- Back to the top

Web Review Websites

Amateur reviews of scopes tend to quite variable in their depth and quality, written as they are by new owners of telescopes with often more enthusiasm than background knowledge for making an objective judgement. However, we've found these sites do provide some useful reviews.

CloudyNights.com
www.CloudyNights.com
Reviews are by a variety of contributors. Anyone can upload their opinion. Reviews range from the laughably amateurish to the thoroughly skilled. You'll soon learn to tell the difference.

ScopeReviews.com
www.ScopeReviews.com

Reviews are by Ed Ting, a very knowledgeable telescope owner and user.

Weatherman.com
www.weatherman.com

Reviews by internet regular, professional meteorologist and experienced telescope user Todd Gross.

Phil Harrington's Star Ware
ourworld.compuserve.com/homepages/pharrington/

Author and telescope expert Phil Harrington posts telescope reviews and comments from readers that could not be included in the latest edition of his excellent Star Ware book.

Excelsis Astronomy Ratings
http://www.excelsis.com/1.0/catalog.php?categoryid=3

Contributors rank their favorite telescopes. Take the ratings with several grains of salt (owners will often defend that their scopes are the greatest) but the tabulations provide some idea of relative customer satisfaction with the many telescope models on the market.

Telescope Manufacturers

We provide links to all the telescope manufacturers mentioned in Chapter 3, and many more besides. First, here are some sites of interest to telescope makers.

Telescope User-Group Sites

Meade ETX telescopes

Mike Weasner's Mighty ETX site: lots of tips here if you can weed out the useful nuggets from the unedited reams of e-messages.

Meade Advanced Products User Group (LX200, etc)
http://www.mapug.com
A compilation of tips and techniques of interest to owners of the original Meade LX200, new LX200 GPS, LX90, ETX-series and Magellan add-on box. Well-organized by topic but extracting the needed information requires reading through a mass of unedited e-mail queries and replies. But this is the best source of help for these popular but, to many people, often puzzling telescopes.

Celestron NexStar telescopes
http//www.NexStarSite.com
Mike Swanson's well-organized support site for users of all NexStar scopes. Contains useful downloadable software.

PLUS... Many smaller manufacturers provide links at their sites to privately-hosted user-group lists, with the manufacturers themselves contributing useful tips and answers. Often there is a FAQ (Frequently Asked Questions) file that can be downloaded from a library site. Please check that first before asking what may be a common question.

For an extensive listing of user groups, go to...

Yahoo Groups for Astronomy
http://dir.groups.yahoo.com/dir/Science/Astronomy

Check the Yahoo astronomy directory. There’s bound to be a mailing list for a user group for the model of telescope, camera, or software you are interested in. There were more than 700 astronomy-related groups in 2002! Some groups allow non-members to search archives; other groups require you to join.
