At Tele Vue, we always try to provide good value in addition to great optical performance. With the Tele Vue-102 we offer the amateur a simpler, less expensive, 4" refractor which retains Tele Vue's core values; outstanding optical performance and superb mechanical quality.
The new Tele Vue-102 is a 4-inch, 2-element f/8.6 APO air-spaced doublet, similar to the appearance to the 4-element f/5.4 Tele Vue-101, but 5-inches longer. The Tele Vue-102 achieves similar diffraction limited, high power APO viewing as its 4" sibling, along with a wide 3 degree maximum visual field (compared to 4.9 degrees for the Tele Vue-101). A dedicated 0.8x reducer/flattener is available to permit great astrophotography of star fields at f/6.9 with the Tele Vue-102. Objective: 102mm Aperture, APO Doublet Focal Length: 880mm Focal Ratio: f/8.6 Max Visual Field: 3.0 degrees @ 16x (55mm Plossl) Length of O.T.A: 30-3/4" Complete Includes: Custom hard shell case, screw-on lens cover sliding dew shield, 2" Everbrite Diagonal, 1-1/4"-2" adapter, Plossl eyepiece, Ring Mount, Ivory Powdercoat or Brass Finish
