Tele Vue 4.0x 2-inch Powermate Review
Review of Tele Vue 4.0x 2-inch Powermate.
Price: 310 USD
Manufacturer: Tele Vue
Tele Vue 4.0x 2-inch Powermate – Product Warranty: Five year
Product Type: Tele Vue > Accessories
These Powermates are a better choice for 2″ diagonals fthan 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 speical 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, reqiring miminal refocus compared to a 2″ Barlow.
