The Society's administrative headquarters and three observatories are located on one acre atop South Mountain in Lower Salisbury Twp. near Allentown, PA. Click here for Google Maps link.
The main building houses a meeting room, the Grady Planetarium, the Robson Library/Computer Wing, a workshop, and an optical room. The planetarium seats approx. forty people, under a 21-foot dome, that has the unique feature of descending to eye level, to simulate a realistic horizon.
The library currently contains over 1000 volumes on a variety of astronomy and physical science related subjects. In addition to the print media, the library also has numerous video and audio tapes. LVAAS Members have accesses to these resources as part of their membership. In addition, members can also rent several portable telescopes and binoculars for a small fee.
The three observatories each house permanently mounted telescopes. Among which is a 6" refractor, a 12" Newtonian and a 12" Cassegrain. Members have free use of these telescopes on a first come basis. (see Membership page for details of becoming a member)
