250mm...$1899
300mm...$2999
Upgradeable to full "Go-To"...
Looking at the non-goto, you could almost get a Servocat or even cheaper the Sitech system for this. Without the ArgoNavis it woudl be a tracking only, but you could use a laptop for both to give goto. With these SW tracking scopes you would need something like EQMOD to get goto with a laptop.
8" 499 (+1000 for slew and track)
10" 799 (+1200 for slew and track)
12" 1499 (+1500 for slew and track)
