Celestron 8 to 24mm 1.25 Zoom Eyepiece & Omni 2X Barlow Lens

In this review the Celestron 93230 8 to 24mm 1.25 Zoom Eyepiece paired with the Omni 2X Barlow Lens is evaluated for hobbyist astronomers who want a flexible, budget-friendly way to change magnification without swapping eyepieces. The bottom line: this kit is best for observers who value smooth zoom capability and clear lunar and planetary views, because the fully multi-coated optics and 8-24mm range deliver crisp images and a useful field of view across low and high power.

Key Features

• Variable focal length: The 8 to 24mm zoom lets users quickly select magnification for different targets without changing eyepieces, making it easier to frame objects.
• Wide compatibility: Both the zoom eyepiece and the Omni 2X Barlow are built for 1.25 in focusers and diagonals, so they fit most amateur telescopes and accept standard 1.25 in eyepieces.
• Multiplying power: The included Omni 2X Barlow doubles the effective focal length of any 1.25 in eyepiece, effectively expanding magnification options without extra eyepieces.
• Comfortable eye relief: The eyepiece maintains 15 to 18 mm of eye relief at different focal lengths, helping users of glasses and prolonged viewing sessions.
• Quality optics: Fully multi-coated glass and blackened internal edges reduce reflections and improve light transmission for clearer, higher-contrast images.

Who It's For

This set is ideal for entry-level and intermediate observers who want a single eyepiece that covers a broad magnification range and for those who appreciate the convenience of a smooth zoom while viewing the moon, planets, and brighter deep-sky objects. It suits users who already own a 1.25 in-equipped telescope and want an affordable way to expand their magnification options without buying multiple fixed eyepieces.

Observers who need extreme edge-to-edge sharpness for wide-field astrophotography or who prefer premium wide-field eyepieces with very large apparent fields of view may want to consider higher-end fixed focal eyepieces instead. Likewise, those requiring very long eye relief for specialty binocular-style viewing should compare alternatives.

Pros & Cons

Pros

• Versatile zoom range provides quick magnification adjustments without swapping eyepieces.
• Omni 2X Barlow effectively doubles available magnifications while preserving eye relief.
• Fully multi-coated optics and blackened edges deliver noticeably improved image contrast and reduced reflections.
• Good balance of field of view and eye relief for comfortable moon and planet observation.

Cons

• Zoom eyepieces can show modest edge softness at some focal lengths compared with premium fixed eyepieces.
• Not optimized for wide-field deep-sky imaging where ultra-wide apparent fields are preferred.

Frequently Asked Questions

Will this fit my telescope?
Yes, it fits any telescope that accepts 1.25 in eyepieces and slides into 1.25 in focusers or diagonals.

Does the Barlow affect eye relief?
The Omni 2X Barlow preserves the eye relief of your eyepieces while doubling magnification, so comfort is largely retained.

Is the zoom smooth to use?
Customers report the zoom action is smooth and easy to adjust across the 8 to 24 mm range, allowing quick changes in magnification.
