Next Planetarium Show / Stargazing Night:

Goodbye Cassini

at Ritchie Observatory is Saturday September 9th, 7:30 pm.

On September 15, Cassini's 13 year exploration of Saturn will end when it plunges into Saturn's atmosphere. We will review the amazing results of this mission. And we will see how a local elementary school is connected to Cassini's fate.

Afterwards, we will observe clouds and/or rain. On the off-chance the sky is clear, astronomers will be on hand with telescopes. Free to members, $2.00 donation suggested for nonmembers, $5.00 for families.

    Deck for the Richie
    This Saturday (2/7/2015) Malcolm, Steve, Nels (l to r) & Marty were busy, knee deep in sawdust, working on the deck platform for the Richie. Once completed, the new deck will provide a single surface for observing at the telescope. A ladder will be needed but it will be much smaller and not tied to the dome. The End Result.
    The Ritchie is now a much more accessible telescope.
