I'm looking for EP recommendations for a binoscope using two 5" f6.4 refractors. Let's say 3 pairs (one high, one medium, and one low power pair).
Particularly, looking for 1.25" EPs that provide:
- high transmission
- very flat field
- approx. 60-65 deg. FOV
- long eye-relief (i.e 15-20mm)
- parfocal
I really like the Pentax XLs/XWs but figure that the eyecups are probably too wide to allow for proper interpupilary spacing. And that is really a shame. Am I wrong on this?
