Next Planetarium Show / Stargazing Night:

3 Stars : A Tale of Stellar Evolution

at Ritchie Observatory is Saturday May 12, 8 pm.


Join astronomer Steve Ruhl as we take a look at the evolution of stars. We will look at 3 "nearby" main sequence stars to learn about red dwarf, mid size, and large stars.

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.
