Astro Systems was founded in 1986 to fill the void in amateur astronomy for reasonably priced, quality telescope kits. Amateur astronomers were able to build their own telescopes without the hassle of finding all of the essential materials. They have since expanded their product line to telescope accessories, such as dew-prevention systems, adapters, and much more. The benefit of purchasing an Astro Systems product is that each product is made by amateur astronomers, for amateur astronomers. They understand that astronomy must be accessible to all, regardless of your budget.

This methodology is apparent in every Astro Systems accessory you will find on our website. For example, they offer two different eyepiece adapters so you, the customer, can make the decision which one is best for you. This also gives you options for additional focus travel, if needed. The popular Astro Systems Secondary Dew Guards also comes in many different sizes to suit a wide range of Newtonians. This secondary mirror heating system maintains the secondary at a preset temperature above the ambient air temperature, making it an essential accessory for any Newtonian owner.
