I saw an ad for these in the latest issue of Astronomy magazine, but don't recall reading anything about them here. According to Orion, these new ED-X2 scopes have one element of FPL-53 ED glass and one element of FPL-51 ED glass in their objective lens assembly. They go on to claim that "With two fluoro-crown ED glass elements and fully multi-coated optics, the...ED-X2 refractor provides superior correction of chromatic and spherical aberrations. By suppressing these aberrations so effectively, this triplet 'apo' telescope produces impeccable visual views and razor-sharp astrophotos without any fringing or loss of clarity."
Orion sells two versions:
1) 85mm @ F/6.6 - 9.25 lbs
2) 104mm @ F/6.25 - 14.6 lbs
They come with "a thread-on objective lens cover, two heavy-duty machined tube rings, a sturdy machined dovetail bar for easy mount attachment, and a dovetail finder scope base (installation required). An included hard carry case with a custom die-cut foam insert ensures safe transport and convenient storage."
Is Orion doing something new here with the X2 design? Would there be much an improvement over single element triplet apos, especially for imaging?
