Baader Planetarium Hyperion IV Click Zoom eyepiece 8-24mm 70-50° 2″-1.25″
Meet the latest addition to the legendary Hyperion series - the Baader Hyperion IV Click Zoom eyepiece. This zoom eyepiece is a smart and practical solution for astronomers who do not want to compromise: instead of carrying a full set of eyepieces, one single piece covers the range from 8 to 24mm with a 3x zoom ratio. Thanks to the unique click-stop mechanism, you always know exactly which focal length you are currently using.
Five precise click-stop positions
The Baader Hyperion IV Click Zoom eyepiece offers five predefined positions with a clear, satisfying click: 8, 12, 16, 20 and 24mm. This is a significant advantage over smooth-action zoom eyepieces, where you can never be sure of the exact focal length. When observing planets or double stars, simply click to the desired position and you instantly know the magnification you are working with - no guessing, no confusion. The transition between positions is smooth, and the mechanism feels robust and reliable for long-term use.
Optics and image quality
The optical system is treated with Phase FMC (Phantom Group Coating) anti-reflection coating, which minimizes unwanted reflections and ensures high image contrast even in demanding conditions - for example when observing the Moon or bright planets. The field of view ranges from 70° at 8mm to 50° at 24mm, which means that even at low magnification you get a pleasantly wide view of large deep-sky objects. The eye relief of 12-15mm is comfortable even for observers who wear glasses.
Astrophotography and accessories compatibility
The eyepiece body features a retractable rubber eyecup with adjustable height - it screws into position and holds firmly at any level. Beneath it is an M54 thread, which allows direct attachment of a camera or other accessories. This makes it an eyepiece suitable for both astrophotography and visual observation in one package. The eyepiece is compatible with both 1.25″ and 2″ focusers. After unscrewing the chrome barrel, the most common connection threads become available, including the bayonet mount for the Carl Zeiss Diascope. This makes it an exceptionally versatile tool for owners of different telescopes and instruments.
Who is this eyepiece for?
The Hyperion IV Click Zoom will be appreciated by anyone looking for a versatile eyepiece for use in the field or at a permanent observation site. Here is how different users can benefit:
- Planetary observers - high magnification at 8mm is ideal for detailed views of planets and double stars.
- Deep-sky observers - at 24mm you get a beautiful wide-field view of nebulae and open star clusters.
- Astrophotographers - the M54 thread makes camera attachment quick and straightforward.
- Beginners building their kit - a zoom eyepiece with a click-stop mechanism is an excellent choice if you want one eyepiece that covers a wide range of magnifications without buying multiple pieces.
