Developed by Al Nagler, Tele Vue Powermate lenses are the first successful attempt to break the limitations and eliminate the flaws characteristic of even the most refined classic Barlow lenses.

Thanks to the innovative four-element Tele Vue Powermate 2x 2 "design, it allows you to obtain a sharp, aberration-free image without changing the exit pupil shift or increased vignetting. Another feature of this accessory is the fact that, unlike Barlow lenses, its optics it does not cause refraction and changes in the course of the light, thanks to which its path is always parallel to the optical axis, which is very beneficial for the quality of observation with the use of narrowband filters such as, for example, Hα.

Powermate lenses are para-local and can be combined in sets with a magnification that is the product of the times of the individual components.

Attention! When selecting lenses from the Powermate series, see the diagram showing the changes in magnification depending on the distance between the lens and the focal plane. The diagram is available on the manufacturer's website at www.televue.com/engine/TV3b_page.asp?id=53&Tab=_app
