BARLOW LENSES ( 3 )
The handy Barlow Lens effectively gives you double duty from every eyepiece in your arsenal! A 2X Barlow, for example, placed between a 20mm eyepiece and the focuser gives you, in effect, the optical performance of a 10mm eyepiece in terms of magnification and field of view.
e-Scopes has economical and high performance 2X and 3X Barlows available in a short design that is perfect for Dobsonian and Newtonian reflector telescopes.
