About Baader Planetarium Eyepiece

If you're an astronomy enthusiast seeking a high-quality, durable, and versatile eyepiece, the Classic Ortho 10mm HT Multi-Coated Eyepiece with Winged Eyecup and 1.25" Barrel is your ideal choice. This innovative eyepiece, designed by the renowned Baader Planetarium, offers a crystal-clear field of view, free from distortions, thanks to its HT-MC coating that ensures high transmission and excellent contrast.

The multi-coating technology effectively eliminates almost all internal reflections, enhancing your viewing experience of celestial bodies. With a 50-degree apparent field, this eyepiece offers sharp field stops and superior ergonomics, ensuring comfortable and prolonged observing sessions.

The classic optical design of this orthoscopic eyepiece features a triplet-element and one plano-convex eye lens, resulting in only four glass-air surfaces. This minimalistic design, coupled with a blackened interior, significantly suppresses stray light, providing you with a clearer and more detailed image.

The hard-anodized barrel of this eyepiece is equipped with a filter thread, adding to its versatility. The anti-reflex coating and blackened lens edges further enhance the viewing experience, making it seem as if there are no lenses at all!

This eyepiece uses the same glasses and optical design as the legendary orthoscopic Zeiss Jena eyepieces, ensuring top-notch performance. The 32mm-Plossl-eyepiece is perfect for a large field of view at telescopes with a 1.25" focuser.

The Classic Ortho eyepiece is also ideal for projection photography, offering high magnifications in combination with an OPFA (Eyepiece Projection adapter). With its high sharpness on the axis and excellent transmission, it provides sharp views of the planets even at very high magnifications.

For afocal projection, the Classic Plossl is perfectly suited when used with the ADPS (Afocal Digital Projection System) and a compact camera with a fixed lens. The lean housing of the Classic eyepieces fits into all common projection adapters and can be used without problems for visual use at any binoviewer.

In summary, the Classic Ortho 10mm HT Multi-Coated Eyepiece with Winged Eyecup and 1.25" Barrel is a user-friendly, high-quality, and versatile tool for any astronomy enthusiast or professional.
