SLAS member Bruce Grim built this 1/3 scale (and fully functional) model of the Big Scope to be installed in the Harmons Observatory at SPOC 2.  Note the doll which, to scale, is the size of a large child. 12 NOV 2000

SLAS member Siegfried Jachmann poses next to the 1/3 scale model of the Big Scope to be installed in the Harmons Observatory at SPOC 2.  Note the position of the eyepiece.  As the telescope utilizes a Springfield mount the eyepiece remains in the same place regardless of where the telescope is pointed. 27 NOV 2000

Bruce Grim checks the view through the "small" scope he installed on the mount to check out the mount's firmness (it is VERY firm).  Note that the OTA which will eventually be installed will be three times the diameter and twice the length of the one shown here.  22 AUG 2001.
