TeleVue  Barlow Lens 5x Powermate 1,25" 

Product description

Al Nagler's 4-element concept, continues the tradition of full-field sharpness with optimum aberration control. Like long eye-relief? Retain the eye-relief of long focal length eyepieces, while at high power. Enjoy, for example, the sharpness and comfort of the 32mm Plössl at up to 5 times the power!

The Powermate consists of a negative doublet plus a positive "pupil-correcting" doublet. This 4-element system provides the magnifying function of a Barlow without its limitations by restoring the field rays back to their original direction, as if the Powermate were not there. The result is a pure magnification increase.

The advantages in a nutshell:


    PowerMate with combination of four lens elements
    no vignetting when observing
    gives an extremely good image
    good edge definition in almost all optical systems
    optimal in conjunction with an H-alpha telescope due to parallel light path
    very robust housing with 1.25" compression ring clamp
    1.25" filter thread
