Baader 2.25x 1.25″ Q-Barlow Lens
The Baader 2.25X Q 1.25″ Barlow Lens fits all 1.25″ eyepiece barrels, focusers, etc. The Classic Q-Barlow has been optically matched to the Classic Eyepieces, and its 2.25X magnification gives a well-spaced set of focal lengths when used with these Baader eyepieces. This Barlow has optics with Baader’s HT multicoatings for maximum transmission and clarity.
Its removable lens cell can also be unthreaded from the 1.25″ barrel, and directly threaded onto any of the eyepieces, to give a 1.3X magnification, further filling in the choice of focal lengths. Alternatively, it can be directly threaded onto the 1.25″ barrel of the Q-Turret to give 2.25X with all 4 eyepieces. This Barlow system provides many options and features not found in other conventional Barlow lens equipment.
