PENDINGi have a pair of antares speers waler ep's i got with a binoviewer - i don't use to much at that mag..
they are 82deg, & were the original competitor to the nagler, eye relief is good at 13mm & they are good in fast scopes to f5-6 (not nagler good). from peter read's website (SDM telescopes) "Nevertheless, the only other ocular to even come close to the Nagler for sharpness, correction and field of view is the Speers-Walerr." though the article is old now
the specs are on this page
