I can vouch for the quality of the Hyperions after owning a set for 18 months. I use mine on the Tak TOA-130 and they perform very well compared to some Televue's and Tak EP's I have owned. They also work extremely well on small scopes such as the ED80/100's. I use a Televue 2.5X Powermate which works brilliantly, the only drawback being the combined weight and overall length of the two together. Definitely excellent eyepieces for people who wear glasses as well.
As an aside, if you screw the 1.25" negative element off the EP, be careful not to get dirt or dust inside as it really shows up badly in the field of view, particularly on the moon. I think that the blackening material/paint used on the inside flakes off when you unscrew the bottom element and it seems to stick to the field lens in an instant and is very hard to blow off or remove.
Cheers,
Steve B
