AstronomyConnect's Community Database is a community driven astronomy equipment database. It contains a vast catalog of current and past astronomical equipment. With the help of the community and our sponsor Agena AstroProducts we hope to have the number one resource in the industry with user reviews, product specifications, product measurements, product resources, and where to buy.
AstronomyConnect's ItemHub DB brings all your astronomy product research to one place. Bringing together a wealth of resources scattered across the web to an easy to use interface. You can filter through our database or use our integrated search to find the product you are looking for. Once on an item page you can read reviews and find resources and related content for the product you are interested in.
