This instrument features the "Porter" or "Springfield" Mount. This is essentially a telescope that moves about the eyepiece which is stationary. The advantages are clear for people who have limited access to the telescope. You can remain in a wheel chair and observe from what is basically part of a declination shaft!!
The telescope is a 10 inch Ritchey Chretien F-30 instrument. It features beautiful brass work.
... Gee well what do you know --- a place to spend money!!
