I think the TOA-130 range uses FPL-53 ED glass. So do some of the AP refractors. I'd say it's fair to assume it is the same glass if a manufacturer say he's using a FPL-53 elements in one of his triplet or quadruplet? TAK or not. I had a look into one of those WO refractors on the jewelbox and I have to say I was on my a$$. It was unbelievably well resolved and separated right down to the very faint stars.

Here's a thread with some really good info related to ED glass vs. Fluorite crystals or mix.
