Sky-Watcher Zoom 8-24mm 1.25" Eyepiece 40-60° AFOV

The Sky-Watcher Zoom 8-24mm 1.25" Eyepiece is a highly versatile accessory designed to fit standard 1.25″ focuser barrels, making it compatible with a wide range of telescopes. This user-friendly eyepiece allows for smooth, adjustable magnification between 8mm and 24mm, effectively eliminating the need to carry multiple fixed focal length eyepieces. Its intuitive design and durable construction ensure that both novice and experienced astronomers can enjoy a seamless zooming experience, transitioning effortlessly from low-power target acquisition to high-magnification detail during a single session.

To maximize observer comfort, the eyepiece features a broad 40° to 60° apparent field of view that facilitates quick and accurate location of celestial objects. It is engineered with a generous 15-18mm of eye relief and fold-down rubber eyecups, allowing users—including those who wear eyeglasses—to observe for extended periods without strain. Built to withstand the rigors of regular use, this reliable eyepiece provides an expansive and immersive viewing experience, making it a dependable choice for years of stargazing enjoyment.

Product Features in Detail

Seamless Zooming Capability

This eyepiece replaces a whole set of fixed-lens accessories. By simply rotating the barrel, you can transition from 24mm (low power) to find your target, down to 8mm (high power) to see fine details on the Moon or planets without ever removing the eyepiece from the telescope.

Optimized for Spectacle Wearers

Unlike many zoom eyepieces that have tight eye relief, this model provides up to 18mm of eye relief. This allows users with glasses to see the entire field of view comfortably, making it one of the most accessible zoom options available.

High-Contrast Optical System

The internal lens elements are treated with multi-coatings to ensure high light transmission and minimize internal reflections. This results in "ink-black" sky backgrounds and bright, crisp views of star clusters and nebulae.

Intuitive Target Acquisition

At the 24mm setting, the wide field of view makes it much easier to "star-hop" and locate faint objects. Once the object is centered, the zooming mechanism allows you to magnify the image while keeping the object perfectly in the center of the frame.

Rugged All-Weather Build

The anodized aluminum housing is designed to be durable and reliable in the field. The internal zoom mechanics are built to operate smoothly even in the cold temperatures often encountered during winter stargazing sessions.

Versatile Filter Integration

The 1.25" chrome barrel is internally threaded, allowing you to attach standard filters. This is particularly useful for attaching a Moon filter or a UHC nebula filter, which will then work across all magnification settings as you zoom.
