There is quite the story behind this telescope that was the first to be housed in our dome.  Next time you visit, ask a staff member!  The 12.5″ Parks mirror, in it’s rotating ring tube, rides on a Byers 812 mount. The 2825mm focal length in a Newtonian design, means a very long tube, and when that was in the dome, the eyepiece was nearly 12′ in the air!  It’s new home in the Starport makes it a much less intimidating climb to view out of this gem. This wonderful donation for Harold Osborne is our longest running telescope, and has been in continuous use since 1991! The Byers 812 mount was just overhauled in 2017 by our good friend Larry Myers, of Mountain Instruments fame…..
