About Baader Planetarium Hyperion
FEATURED REVIEWS
Baader Hyperion eyepieces are provide great bang for the buck
I am an experienced amateur astronomer and I am currently converting my primary eyepiece set over to Baader Hyperions. These eyepieces provide a clear, wide field of view that rivals more expensive brands such as Televue. The only feature I don't like it the eyepiece guard which is separate rubber ring and is not incorporated into eyepiece casing.
Nice eyepiece!
Great contrast and clarity, good color. Nice wide view with good sharpness almost to the edge.

The Hyperion eyepiece is a testament to Baader Planetarium's commitment to delivering world-class performance and unique photo-visual features without requiring amateur astronomers to invest more in their eyepieces than their primary instruments.

The innovative design of the Hyperion eyepiece ensures superb sharpness and color fidelity, even in fast telescopes.
