Bundle Hyperion Zoom Mark IV + Barlow 2.25x – 8-24 mm Zoom Eyepiece

Bundle Hyperion Zoom Mark IV + Barlow 2.25x – 8-24 mm Zoom Eyepiece

DESCRIPTION
The Hyperion Zoom Mark IV + 2.25x Barlow bundle is a highly versatile solution for visual astronomy and classic eyepiece projection. It combines the Mark IV Hyperion 8–24 mm wide-angle zoom eyepiece with a specially matched 2.25x Barlow lens, expanding the effective focal range to 3.6 to 24 mm.

Ideal for travelers and visual observers focused on lunar, planetary, and double star observation, this bundle performs impressively across the entire zoom range. The eyepiece features ClickStops at 8, 12, 16, 20, and 24 mm, and delivers apparent fields from 48° to 68°. The reversed optical design ensures highest sharpness at short focal lengths – unlike most zooms.

The included Hyperion Barlow screws directly onto the 1¼" nosepiece and converts focal lengths from 8–24 mm to 3.6–10.7 mm, while maintaining high contrast and clarity. It also includes a T-2 adapter, enabling DSLR or astro camera connections via a standard T-ring.

Several accessories are included: adjustable height eyecup, classic and winged rubber eyecups, multiple dust caps, SC and M43 threads, and a belt holster pouch.

Note: this bundle is for astronomy use only. With spotting scopes, the eyepiece can be used alone (without Barlow).
