Recently, in this forum and another, it has been stated by a knowledgable source (Vic Maris), that the SV102EDT used "short flint" SF3 glass in it's lens design.
When the SV102EDT was being produced, there was controversy regarding it's color correction and lens design.
To hopefully clear up a lingering question about this scope's optics, I'd like to know if the EDT used ED (Extra-low Dispersion) glass.
If so, what was the ED glass?
Vic??
Thanks.
