Unbranded Orthoscopic 25mm (1.25) (Pre-owned)

This unbranded orthoscopic 25mm has high quality lenses, even if the maker is unknown. The eyepiece is free of scratches and visible use, and has a clear, un-fogged lens. The wide and well-lit field of view of this eyepiece makes it a great option for looking at objects with large angular diameters, such as the moon, open clusters, nebulae, and close galaxies. Threads on the back of the eyepiece allow for use with 1.25" filters. Reasons to buy this eyepiece include:

Performance

• Good Optical Quality: Orthoscopic eyepieces are known for their simple, high-quality optical design. They generally offer sharp, high-contrast views with minimal optical distortion, making them excellent for planetary and lunar observations.
• Minimal Chromatic Aberration: The orthoscopic design helps reduce chromatic aberration, providing clearer and more color-accurate views.

Versatility

• General Use: A 25mm focal length eyepiece is versatile, offering a wider field of view and lower magnification. This makes it suitable for observing a variety of celestial objects, including star clusters, nebulae, and galaxies.
• Compatibility: The 1.25" format is the most common eyepiece size, compatible with most telescopes.

Practical Considerations

• Ease of Replacement: If you lose or damage an unbranded eyepiece, replacing it is less costly compared to a high-end branded one.
• Learning Tool: For beginners, using unbranded eyepieces can be a practical way to learn and understand what features and specifications are most important to them before investing in more expensive equipment.
