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 a combination of four lenses
  • no vignetting when observing
  • extremely good image
  • good edge definition in almost all optical systems
  • optimal when used together with an H-alpha telescopes due to parallel optical path
  • very robust housing with 2" barrel and 1.25" reducer with compression ring clamp
  • 2" filter thread
  • the 2" PowerMate can be separated and an (optional) T-ring can be attached for photography
