Bausch & Lomb Criterion 4000 Telescope System



Image 1, 2

Hardware seems to be in good condition and clock drive appears to be working.  Corrector plate is loose, so optical system will need to be aligned, and collimating will likely be necessary.  Have not made any observations with this system, so cannot speak to the optical performance.


General consensus in chat rooms is that the mount is very solid, but optics are quite bad for this telescope.


Included Items

  • Tripod Wedge

  • Carry Case

  • Base Leg Set

  • For Mount with Clock Drive with 120v power cable

  • Optical Tube Assembly

  • Small Finder Scope

  • Star Diagonal

  • 2x Barlow lens (1.25" Barrel)

  • Nikon T mount adapter

  • Cassegrain Focus Adapter

Cloudy Nights: Display Fix

Hardware appears to be fine except for the hand control display.  This seems to be broke.  Bypass the solar warning by pressing #5, and the control can be used to drive the telescope.

Looks like a display can be purchased and soldered on the unit for about $30(see resources).  Otherwise a new hand controller will run about $200 from Meade (or you can see if you can find a used one).

  • Moterized Fork Mount with Clock Drive
