Condition:  This is a 10" Quattro 250P that is about 3 years old and is in excellent, like new condition.  There isn't a mark, scratch, or ding anywhere on this OTA. 

This scope was simply too much for the previous owner, who didn't use it and downsized instead.  Completely clean mirrors.  Includes the 50mm finder scope, and the clamshell mounting rings with the Vixen dovetail attached.   It also includes a brand new Celestron collimation eyepiece.  

This like new model is a huge savings off of the new price, so this one won't last!  Local pickup only, no shipping boxes.


  • 254 mm Newtonian reflector
  • 1000 mm (f/4)
  • Fully multi-coated borosilicate mirrors
  • 2” dual-speed 10:1 linear power focuser
  • 8×50 finderscope
  • Tube rings with V-style dovetail bar

The new Sky-Watcher Quattro Imaging Newtonian with dual-speed focuser incorporates a superb mirror-set with two significant advantages over competing products. A 2″ dual-speed 10:1 ratio focuser is included for excellent focusing precision. Additionally, the tube length has been slightly shortened to optimize performance for prime-focus photography. Even better performance for astro-photography, and visual use, can be achieved when used in combination with the Sky-Watcher Quattro coma corrector.
