Baader Planetarium Hyperion Zoom Barlow Lens

While this lens is specifically engineered to be optically matched with the Hyperion 8-24mm Clickstop Zoom eyepiece, its 1.25-inch barrel allows it to function as a standard Barlow with other eyepieces. However, you will achieve the best optical performance and flat-field correction when used with the intended Hyperion Zoom system.

It is designed for both. The modular construction includes a T-adapter, which allows you to easily attach a camera for projection imaging. It functions effectively as a flatfield projection optic, making it a versatile tool for capturing high-magnification planetary or lunar images.

The air-spaced triplet design is a high-end optical configuration that helps correct aberrations, specifically field curvature. This results in a flatter field of view, meaning your stars or planetary details remain sharp and distortion-free from the center all the way to the edge of the frame.

Unlikely. Baader uses their proprietary Phantom Group multi-coatings, which are specifically designed to minimize internal reflections and maximize light transmission. Additionally, the interior is baffled to eliminate stray light, ensuring high contrast even when viewing bright objects like the moon.

Yes, it provides a 2.25x magnification factor. When used with the Hyperion Zoom eyepiece, it effectively multiplies the focal length of your telescope by 2.25, giving you a much tighter field of view and higher magnification for detailed planetary observation.
