Use the Observatory's telescopes to get an up-close look at the Moon in celebration of International Observe the Moon Night. This event will begin in daylight and last through dusk.
View the Moon's craters, maria, and other features using the Observatory's Cook Memorial Telescope, a historic 16-inch Cassegrain reflector. There will also be smaller telescopes set up to observe the Moon, and knowledgeable astronomy educators will be available to provide information and answer questions.
Accessibility: The terrace and Observatory dome are accessible. Viewing through the main telescope is fully accessible to all visitors with an extended eyepiece.
This event is dependent on clear weather. Closure updates will be posted on Twitter @SIObservatory.
This image of the waxing, slightly gibbous Moon was taken after public viewing on December 3, 2011, at 7:50 pm, with the 85mm Televue telescope. The broad, smooth maria are visible at top, and white Stevinus Crater to the lower right. Heavy cratering is seen in the lunar highlands along the terminator.
