I'm currently researching several 100-115 scopes. One of these is the W.O. FLT-110. I'm trying to find an APO refractor, preferably a triplet design, that's priced within my budget ($3000). I'm also trying to maximize color correction. The FLT-110 is a triplet design by TMB. However, I can't seem to find the specifications of the type of glass used in the objective. Does anyone know if the optics incorporate an FPL-51, 52, 53, or some other type of glass element?
Regarding William Optics FLT 110...

The last statement by William Yang was that the new triplets are made with OK3, which is a glass that is similar to FPL51, but not the same. It is not Fluorite, nor FPL53 if his statement is correct.
The real question is, how well corrected is the design regardless of the glass used? I

Of you look at the diagram in this document by Tom Trusock, it shows the color correction according to William Optics. This is for a 2005 scope. Not sure but I think it is the same as the current model.

Hi,
WO has confirmed that it is FPL-51 - same as they used in the previous version - post from WO on Cloudy Nights here includes comments from WO directly
