1 Sawin Observatory


The Sawin Observatory is the main observatory of the Delaware Astronomical Society.  It has two telescopes and is very handy for a quick visit. SPECIAL NOTE: Laser pointers are strictly prohibited at this location due to its proximity to significant air traffic. Your cooperation is appreciated.




The DAS maintains The Sawin Observatory on the grounds of the Mt. Cuba Astronomical Observatory. 

The Sawin Observatory houses the club’s equatorially mounted 12.5" reflecting telescope. The Sawin is also currently home base for our 17.5" split-tube Dobsonian telescope.

DAS members can obtain a key for access to the Sawin Observatory through a certification program for use of these telescopes and the observatory. Naturally, all DAS members and their guests are invited to look through these telescopes during our Star Parties at the Sawin. DAS members who are interested in obtaining their Certification for the Sawin Observatory should contact This email address is being protected from spambots.
