- Allows you to use 1.25" eyepieces in any 0.965" telescope focuser, star diagonal or holder.
- For older telescopes that used 0.965" eyepieces.
- All metal construction with anodized aluminum.
Several older telescopes have a focuser or star diagonal for eyepieces with a 24.5mm (0.965") barrel diameter. It is possible to use newer 1.25" eyepieces in combination with this adapter. Adds approximately 30mm to the eyepiece focal point (may not be compatible with some older newtonian telescopes).
