Used Tele Vue TV-102 Apochromatic Refractor w/Starbeam - SOLD -

The objective lens of the 102 is of an SD air spaced doublet design where two lenses (crown and flint) are matched to work as one; the positive element is of a fluorocrown substitute with special dispersion glass. In fact this design allows excellent color correction without annoying purple fringes (secondary color) common to less sophisticated achromatic refractors. And it will perform better than a number of older triplet and modern doublet apochromat designs. There will be a barely perceptible false color in this design, and what there is may be visible only to the more discriminating observers when using the telescope at very high magnifications well in excess 300x on some of the very brightest starts. Spherical correction is very good also with the air gap objective contributing to this correction. Images of the stars and the planets are presented in their natural colors, daytime objects viewed at commonly used magnifications will appear quite three dimensional, sharp and high in contrast.
