Welcome to the Eileen Collins Observatory!


Open 1st and 3rd Fridays from 8:00pm-10:00pm


"Photodynamic Therapy - The Healing Power of Light"

Talk given by Dr. Corey Stilts from Elmira College
at Elmira-Corning Astronomical Society meeting
7:30pm on Friday, February 5, 2016
Free and open to the public

Photodynamic Therapy (PDT) is a bimodal method of chemotherapy that requires a light sensitive non-toxic sensitizer and a light source to be effective.  PDT has been used a method to treat specific cancers since the late 70’s and more recently to treat bacterial infections.  Dr. Stilts’ group has focused on both the development of a new approach to synthesizing porphyrin-based photosensitizers and their use to treat bacterial infections. They are currently working on the solid phase synthesis of porphyrins as well as determining the effectiveness of sensitizer concentration and bacterial colony age on PDT treatment.


We have many types and sizes of telescopes here at our Observatory. Our two largest telescopes are both reflectors - the 20" and the 16". Our 20" telescope is the one-tenth scale model of the Hale Telescope at Mount Palomar in California. We also have 14", 12", 10", 8", and 6" reflectors that were built by members of the Elmira-Corning Astronomical Society. We have 8" Schmidt-Cassegrain reflectors in addition to 4" refractors and a solar telescope. All of these telescopes are on display at the Observatory. Some of them can be used by the public during our Friday night observing sessions.
