Tele-Vue Powermate 2.5x. LNIB $145 shipped in CONUS.

Besides the usual comments on quality , let me add that this
'amplifier' has attributes which are not apparent but can make a significant difference depending on the eyepiece and telescope used.
If you have one of the new 16mm type 5 naglers, this will give a fully illuminated distortionless field of view. I tried my Ultima barlow and 2x Tele-Vue , both vignetted significantly and added some distortion and glare to the image. When used with the Ultima or Tele-Vue 2x barlow placed first and then inserting the 2.5x PowerMate, the resulting 5x field is also perfect.
It gives wonderfully corrected, unvignetted fields with other long and short focal length eyepieces. In addition it is parfocal with most Tele-Vue eyepieces, while with others it may be close to parfocal or even require 'out' travel. This can be very helpful in some scopes which have limited focus travel or are optimized for minimum diagonals and use ultra short focusers.
This powermate is absoutely mint,just one month old. Box,caps and
Tele-Vue product description included.
