Home

¥ Welcome to my FREE and NON-COMMERCIAL collection of astronomy links!

¥ Some individual links are in ALL CAPS to indicate their extra value.

¥ For frequent visitors I have included a NEWEST LINKS section for temporary placement of my latest additions.

¥ I have resisted the urge to create too many categories, for two reasons: First, many links would properly
belong to more than one category. Second, I want to encourage you to browse and discover.

¥ This site is not an encyclopedia, just one amateur astronomer’s inspiration for what star gazers
at all levels of experience would like to see.

¥ If this site earns your approval, please put a link to it on your own web site.

¥ To share with me, or to report non-linking links, just email me.
