A high-power accessory for visual astronomy: perfect for lunar and planetary observing when used with a telescope compatible with the .965″ size. The optics are clean and fully functional, the barrel threads smoothly and fits securely. Because of the 0.965″ size and short focal length, it offers very high magnification — please ensure your telescope setup is capable and stable. Ideal for collectors of vintage astro gear or observers seeking a budget high-power option.
Key Features:
-
Focal length: 4 mm (very short). Helps achieve high power when used with a telescope of modest focal length.
-
Barrel size: 0.965″ (24.5 mm). Important to note, as this is a vintage/older telescope standard rather than the more common 1.25″ or 2″ today.
-
Suitable for all telescope types that accept a 0.965″ barrel: refractors, reflectors, etc.
- Because of its very short focal length, this eyepiece will deliver very high magnification, which can be ideal for lunar or planetary observing, but may be less forgiving: you’ll need a stable mount, good focus, and good seeing conditions.
