9mm or less

As a visual eyepiece, we have found the Hyperions deliver superb sharpness and color fidelity across their 68° wide, flat-field, even in fast telescopes. In our own comparisons to our personal favorites, the Pentax XL, the Hyperions matched the Pentax in every regard, and at just over 1/3 the price! From their superb on-axis and off-axis sharpness, to their pitch-black high contrast field, the Hyperions really work. Viewing through a Hyperion is notably comfortable and relaxing, due to their forgiving eye-position, 20mm of eye-relief, and an optical design that is free of the annoying kidney-bean effect.

The Baader Hyperion 8-24mm Clickstop Zoom continues the Hyperion tradition of delivering top-of-class performance and quality, at very reasonable prices

The 2.3mm high power X-Cel eyepiece is a 6-element fully multi-coated optical design, the X-Cel utilizes extra low dispersion (ED) glass on its most highly curved surfaces, to minimize chromatic aberration that can hinder sharp planetary views. With a wide 55° apparent field of view, and a large 25mm clear aperture the X-Cel is one of the most comfortable eyepieces to use.

• Wide field of view enhances views of the night sky through a single lens
• 6-element fully multi-coated optics create sharper images
• Extendable twist-up eyepieces are easier and more comfortable, especially for eyeglass wearers
• No slip, rubber grip ring for secure handling, even in moist conditions
• Parfocal eyepiece require little to no focusing when changing from low to high power

The 4mm high power Omni eyepiece is a 4 -element premium symmetrical Plossl optical design. Features include blackened lens edges to minimize internal reflection and maximize contrast, multi-layer coating group on each lens surface to maximize light transmission and contrast, and each Omni goes through a two-step anodizing process to prevent reflection from the top eyepiece barrel, unlike most other manufactures who use reflective surfaces.

• 70 degree Field - Wide FOV for high and low magnifications
• Extendable twist-up eyecups - Good for eyeglass wearers
• Parfocal eyepiece - Little or no focusing is needed when changing from low to high power.
• Threaded barrels - Accept 1.25" Celestron thread-in filters.
• Shock resistant rubber covering - Scratch and dent resistant
• No slip grip - Designed for secure handling even in moist conditions
• Roll guard - Ergonomic contours prevent eyepiece from rolling off flat surfaces
• 28 mm clear aperture surface lens - For comfortable viewing
