  1. Pentax 8-24mm SMC 1.25" long eye relief astronomical zoom; 21-63x or 26-78x spotting scope zoom

    This is an ultra-premium six-element zoom eyepiece with surprisingly good eye relief for those who must wear eyeglasses while observing. Designed for use with Pentax spotting scopes, it can also be used for astronomical observing in any telescope accepting 1.25" accessories . . .
  2. Lunt 7.2mm to 21.5mm zoom

    While the 7.2mm to 21.5mm focal length of this Lunt Solar zoom eyepiece specifically complements the Lunt H-alpha refractors for solar observing, it works equally well for nighttime astronomical observing . . .
  3. 8-24mm long eye relief zoom

    This Meade 8- 24mm zoom eyepiece has its focal lengths marked in 1mm increments for repeatable power settings (for example when two eyepieces are used in a binocular viewer) . . .
  4. Tele Vue 3mm to 6mm Nagler 1.25" zoom eyepiece

    Unlike an ordinary zoom eyepiece, this high power Nagler zoom maintains a constant and substantial 50 degree apparent field of view at all focal lengths and the usable eye relief stays a constant 10mm . . .
