1¼"
Powermates: 2.5x / 5x
|
These models stand
less than 3" out of your focuser and the 5x take 1¼" threaded
filters. They are parfocal in ALL 1¼" diagonals and prisms. For
this reason, they are highly recommended over standard Barlows
for 1¼" refractors such as the Tele Vue Ranger.
The 5x Powermate™ is ideal for long focus CCD
and film photography, magnifying about 7.7x. It’s an attractive,
high performance alternative to eyepiece projection. The 5x is
also perfect for slowing down your scope for Hydrogen-Alpha solar
observing. |

Powermates:
2x / 4x
|
These
Powermates™ are a better choice for 2” diagonals than Barlows, since
they are nearly Parfocal. They are threaded for 48mm filters and
their performance is excellent with every 1.25” and 2” eyepiece
we make (yes, even the 31mm Nagler Type 5!). Both the 2” eyepiece
holder and the special 2” flat top adapter use our brass clamp rings
for secure operation. And, it also has a very unique feature: you
can unscrew the 2” eyepiece housing and screw on a special T-ring
adapter for solid, compact attachment of CCD or camera equipment.
Excellent with long eye-relief, 2" eyepieces.
Using the 4x model, imagine the quality of a 35mm Panoptic at
8.8mm with 25mm of eye relief! The Powermate™ is NOT a Barlow
so the Panoptic-Barlow Interface is not needed! The 2" Powermate™
fits all the way into 2" Star Diagonals, requiring minimal refocus
compared to a 2" Barlow. |

1¼"
Barlows:
2x / 3x
|
Offered
in 2x and 3x magnifications, these 1¼" Barlows perform
identically. Simply choose either or both based on your eyepiece
collection. Features include parfocal-ization, 1¼" filter
threads, captive lock screws that won't fall out and full multicoatings. |

2"
Big Barlow
|
Offered
in a 2x magnification, the Big Barlow is ideal for Newtonian scope
owners. It will be parfocal with both 2" and 1¼" eyepieces
in this application. Features include threads for 48mm filters, captive
lock screw and full multi-coatings. |
|
|
Barlow Interface
|
You
can double the power of any eyepiece with the 2x Big Barlow,
but adding the interface lens brings the pupil back to original position
when used with long focal length eyepieces such as the Panoptic 41,
35, or 27mm 2" models. The combination of interface and Big
Barlow mimics the Powermate concept. |
