I have an 18" Starmaster for sale with the following specs:
Stabilite hollow-cell Zambuto mirror - cools down fast and stays at ambient temperature.
Sky Commander DSC's and Sky Tracker GOTO drive
JMI DX-1 2-speed focuser
Astrosystems secondary dew heater
Wheelbarrow transport handles
I have made the following modifications to the scope:
Added a ring baffle behind the mirror cell to keep stray light out from behind (removeable).
Replaced Astrosystems secondary heater wiring with conductive tape on secondary vane (much thinner than the wire). Also put the connector to it through the secondary cage near the focuser for easy access.
Added a fan that blows into the hollow cells of the Stabilite mirror for even faster cooldown.
Added Protostar flocking paper to the secondary cage and along the truss poles.
Scope is in excellent condition. New cost for current Starmaster 18" Goto is $9700. The Stabilite mirror was $1000 extra at the time (Stabilite mirrors are no longer avaiable, and I believe that this is the only one Carl Zambuto figured).
I would prefer not to ship this scope. I am willing to drive up to 500 miles in any direction to deliver or meet you to pick it up. I will be at the Peach State Star Gaze with this scope next weekend (October 24-25). I am asking for $9000 if I have to drive a significant distance to deliver, or $8500 if you pick it up here in Atlanta or at the PSSG.
