MAS Observing Sites & Facilities

Observing in all its forms is the heart and soul of amateur astronomy. To meet our membership’s diverse observing needs we maintain five unique regional observing sites, four with observatories. Each site includes observing amenities, ranging from a simple warming structure and concrete pads to a fully-equipped observatory housing multiple telescopes. Star parties take place at each site on a rotating basis. Four are also available to MAS members for private use.
