What type of ED glass does the TV 102 incorporate into its doublet design? Anyone know?

Hola Francisco,

Tele Vue does not disclose the glass type used. Good thing too in my opinion as we can see recently how so many people focus on FPL53 vs whatever and lost sight of the mating element ;-).

The end result is what count.

For a while I was bothered by the fact that Tele Vue would not disclose the kind of glass that they use in their doublets. Now I am much less so after following all the threads about the FPL53 mystery and the fluorite apo that was not.

Truth is that I wholeheartedly enjoy by 2 Tele Vue refractors. They are simply the product of great engineering and beautiful manufacturing. Where it counts the most, at the eyepiece, there is nothing for me to complain about.
