Eyepiece Telescope Baader Planetarium 2454605 Black 1.25 inch

The Baader Planetarium 2454605 eyepiece is a 1.25 inch accessory designed to improve visual performance of telescopes. Built with a robust housing and precision optics, the eyepiece delivers clear and detailed views of planets, the Moon, star fields and other celestial objects. It is compatible with standard 1.25 inch (31.7 mm) focusers and visual backs used in many amateur and semi-professional telescope setups.

Advantages

This eyepiece combines durable mechanical construction with optical elements engineered to provide good contrast and sharpness across the field of view. Its standard 1.25 inch format ensures wide compatibility with most telescopes and accessories, while the solid build minimizes flex and play during insertion and removal. The design supports comfortable eye placement and reliable alignment for repeatable observations.

Suitable for

• Planetary and lunar observing with refractors, reflectors, and catadioptric telescopes
• Deep-sky viewing of star clusters and brighter nebulae at moderate magnification
• Visual astronomy sessions, public outreach, and educational use

Key specifications

• Eyepiece barrel diameter: 1.25 inch (31.7 mm)
• Optical design: multi-element eyepiece optimized for visual use
• Mechanical finish: robust metal housing for secure mounting
• Compatibility: fits standard 1.25 inch telescope focusers and diagonal adapters
• Use case: visual observation of solar system and selected deep-sky objects

How to use

Insert the 1.25 inch barrel of the eyepiece into the telescope focuser or diagonal and secure it with the focuser’s clamp or set screw. Begin with low to medium magnification to locate the target, then adjust the focuser for a sharp image. For planetary detail, increase magnification as seeing conditions allow; for wider star fields or clusters, use it at lower power. Handle the eyepiece by its housing and avoid touching optical surfaces; if necessary, clean lenses with appropriate optical cloths or solutions following manufacturer guidelines.

Usage recommendations

Use this eyepiece with a stable mount and well-collimated telescope to achieve the best image quality. Allow the optics to reach thermal equilibrium with ambient temperature before high-magnification observing, and protect the eyepiece from dust and moisture when not in use.
