Fuertes Observatory Hours and Directions

Fridays from 8pm until midnight

Please do not arrive early to public viewing nights! CAS has club meetings until from 7:30 to 8pm on most Friday evenings, and our volunteers will not be ready to set up for observing until 8pm. 

For lectures and other special events, the doors will open 30 minutes before the scheduled start of the event. 

We are generally open every Friday night throughout the year, regardless of weather. On cloudy nights, we give tours of the building and its historic astronomical equipment.

Due to Daylight Savings Time and more hours of daylight in the spring and summer, observing often does not begin until 9pm in the warmer months.


Call (607)-255-3557 to find out what our current schedule is and to see if we are open!
