Over two decades of carefully curated astronomy resources. Since 1994, Sirius Lookers members have been collecting and sharing the best online resources for amateur astronomers. This collection represents hundreds of hours of stargazing experience distilled into the sites we actually use.

About This Collection
This link collection has been maintained by Sirius Lookers since we launched our first website in the early 2000s. Many of these resources were discovered through years of active observing, star party conversations, and recommendations from fellow club members.
In 2025, we restored and updated this collection from our website archives spanning 2006-2022. While some historic links are no longer active (the internet changes!), we’ve preserved the valuable resources that stood the test of time and added descriptions to help you find what you need.
“The best telescope is the one you use the most. The best website is the one that gets you outside looking up.”
— Dennis Young, Sirius Lookers Founder
