william optics annouces new 150mm and 158 mm ed sc

It seems WO has announced a few new OTA's that will be skown at NEAF this spring. A 150 mm apo and a 158 mm apo both are triplets using fpl-53 glass. The 158mm is F7,, the 150mm is F8 , and the 98mm in a F/6 APO.
I could not find and images on the Internet but pretty exciting stuff!

That's an odd size. I wonder why they didn't just go 2mm larger.

Not to dampen the excitement over these new offerings but... the type of glass does not a good scope make. I believe someone like Roland could build a scope out of window glass better than some Far Eastern optical houses could using fluorite elements. (Maybe a slight exaggeration) There are so many processes involved in making a quality refractor besides just what type of glass is used. Even the quality control of the fpl-53 melt can vary wildly from different suppliers and some manufacturers have a somewhat shady reputation about letting almost any blank pass through QC. Going from a 132 mm to a 158 mm at F7 increased the difficulty of making a proper lens group by a magnitude at least. I am not saying these W.O. offerings will be anything less that first rate quality, I hope they are excellent. I just find the advertising hype over glass types to be a bit of a straw dog when discussing top notch refractors.

I repeat myself. How much?
