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.
