Dune Climb Setup

This is the beginning of setup for the October 21, 2017 star party at the dune climb. Taken early while there was enough light. The dune blocks up to 12 degrees from the southwest to northwest, but the rest of the horizon is quite low. Venus will be high enough to clear the dune for most of the evening.  The ladder is up to assemble the society’s 25 inch “Emmettron” Obsession Dobsonian telescope.  The telescope was overhauled including having the mirror aluminized and new encoders over the winter, thanks to Don Flegel our telescope wrangler.  Click to enlarge.  Photo by Bob Moler.
