| Tele Vue Bandmate Nebustar UHC 2" Eyepiece Filter.
by Tele Vue
Bandmate filters yield bright, sharp and contrasty images - even in the optically sensitive position in front of the diagonal. Optical glass and red filtering allows for sharp and bright views of nebulae with embedded star clusters - such as the Lagoon Nebula (M8).

| Tele Vue 2x Powermate, 2" Image Amplifier
by Tele Vue
This model is nearly parfocal (unlike the Big Barlow / Interface combination), so it can be effectively used in our 2" diagonals. Its performance is excellent with every 1¼" or 2" eyepiece we make (yes, even the 31 Nagler Type 5!). Both the 2" eyepiece holder and the special 2"-1¼" low-profile adapter use brass clamp rings for secure, non-marring 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...

| Tele Vue 4x Powermate Barlow Lens 2".
by Tele Vue
Tele Vue Barlows: "An Optically Perfect Window " Properly designed Barlows do wonderful things. First, they amplify power while retaining the eyepiece's eye-relief. Second, they slow the telescope's f/#, which improves eyepiece sharpness. Third, the designer can introduce compensations for eyepiece aberrations. The 4X Powermate Barlow is a 4-element parfocal, compact amplifying lens system. POWERMATE consists of a negative achromatic doublet plus a positive "pupil-correcting" doublet. While...

Product Description
Concept: CCD cameras have challenged telescope optics beyond anything ever placed at the focal plane. Tele Vue knew it's APO objectives were up to the challenge, & with the proper tweaks would be extraordinary tools for the imager. With Tele Vue Imaging System (is) telescopes, they have refined their instruments & optional equipment beyond anything a CCD chip has seen.It started small (literally) in 2005 with the Tele Vue-60is & available Digital Micrometer Kit. Achieving critical acclaim with the 60is, Tele Vue was encouraged to further develop "is" telescopes & accessories to maximize aperture, real field coverage & performance, & to make the processes easier for the imager.For 25 years, Tele Vue has pushed the boundaries of APO refractors, & eyepieces, to the recognized pinnacle of performance. They were gratified but not surprised that Backyard Astronomer's Guide said of the NP101: "optics don't get any better than this." No wonder "Sky and Telescope" rated the NP101 tops & selected it as the test instrument for its landmark review of the SBIG STL-11000 CCD camera. The "is" versions of the Tele Vue- 60, 102i, NP101 & NP127 retain the exemplary wide field & planetary visual capability while adding new features to make imaging easier & more flexible.Tele Vue-NP101is Tele Vue-NP127is:Tele Vue was determined to make the NP series optically, mechanically, & functionally as perfect as poss |
