24mm Ultima Edge 1.25" Eyepiece

The Bower 24mm Ultima Edge 1.25" Flat Field Eyepiece is designed for astronomers seeking edge-to-edge sharpness across the full field of view. Its 8-element lens configuration in 5 groups delivers a flat field design that eliminates quality drop-off at the edges. This eyepiece suits observers who demand high image fidelity for planetary and deep-sky targets.

29mm Eye Relief and 65° Field of View

A generous 29mm eye relief allows comfortable extended viewing sessions, even for eyeglass wearers, reducing eye strain during long observations. Fully multi-coated optics maximize light transmission for brighter images with enhanced contrast. The wide 65° apparent field of view provides an immersive window for expansive celestial vistas and detailed planetary observations.

For Visual Observers Prioritizing Flat Field

This eyepiece suits visual astronomers who want a flat field, long eye relief, and wide apparent field in a 1.25" barrel format. It is not for users requiring a 2" barrel diameter for even wider true fields, nor for astrophotographers needing a dedicated camera adapter or specific thread interface not mentioned here. Buyers seeking higher magnification or shorter focal lengths should look at other models.

Questions about this item

Will the 8-element, 5-group lens assembly ever need internal cleaning or re-collimation?

The sealed 8-element in 5-group design is factory-aligned and not user-serviceable; internal cleaning or re-collimation is not required under normal use.

Does the 65° apparent field of view remain sharp to the edge during long sessions?

The flat-field optical design maintains edge-to-edge sharpness across the full 65° apparent field even during extended viewing.

Does the 29 mm eye relief prevent heat build-up or fogging during all-night use?

The long 29 mm eye relief keeps your eye well back from the eyepiece lens, reducing dew formation and minimising heat transfer during prolonged sessions.
