DESC: 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. The Tele Vue-102 is offered as a complete package or as an O.T.A., since you may already own a 2" diagonal and adapter as well as an eyepiece collection and mounting rings.
