Celestron 93326 Omni Barlow Lens 2x 1.25 in - Boosts Magnification

In this review the Celestron Omni 93326 2x Barlow Lens proves to be a practical, low-friction upgrade for amateur observers who want to double their eyepiece options without buying extra oculars. It is primarily for owners of telescopes with standard 1.25 in focusers who need a simple way to increase magnification and preserve comfortable viewing distance. The single biggest reason to buy is that it reliably doubles the power of any 1.25 in eyepiece while maintaining good light transmission thanks to its fully multi-coated optics.

Key Features

• Enhanced Magnification: Doubles the magnification of any 1.25 in eyepiece, instantly expanding the range of powers available from a small eyepiece set.
• Superior Image Quality: Fully multi-coated optics maximize light transmission and reduce internal reflections for brighter, clearer views.
• Increased Eye Relief: Effectively doubles the useful eye relief of paired eyepieces, making longer viewing sessions more comfortable, especially for eyeglass wearers.
• Versatile Compatibility: Accepts standard 1.25 in eyepieces and focusers so it fits most amateur telescopes without adapters.
• Precision Barrel Design: The precision-machined 1.25 in barrel provides a snug fit in the focuser, minimizing vignetting and keeping the optical axis properly aligned.

Who It's For

The Omni 2x Barlow is aimed at beginner to intermediate observers who already own a couple of 1.25 in eyepieces and want to double their magnification options without extra expense or added weight. It is especially useful for those using refractors or small reflectors where swapping eyepieces frequently is inconvenient.

Observers seeking exceptionally high-end optics or complex focal reducers/expanders should look elsewhere, but anyone wanting a compact, easy-to-use accessory that delivers more magnification and maintains good contrast will find this a solid choice.

Pros & Cons

Pros

• Reliable 2x magnification that effectively doubles available eyepiece powers.
• Fully multi-coated glass that improves brightness and image clarity in most observing conditions.
• Comfortable eye relief when used with existing eyepieces, beneficial for eyeglass wearers.
• Precision 1.25 in barrel fit that reduces wobble and vignetting in the focuser.

Cons

• Some customers report mixed impressions of brightness depending on telescope and sky conditions, so performance is system-dependent.
• Not a substitute for higher-end multi-element Barlow designs if extreme correction of optical aberrations is required.

Frequently Asked Questions

Will this fit my telescope?
Yes, it accepts standard 1.25 in eyepieces and fits standard 1.25 in focusers used on most consumer telescopes.

Does the Barlow affect eye relief?
When used it effectively doubles the eye relief provided by the eyepiece combination, which helps comfortable viewing, especially with glasses.

Does it reduce image brightness?
Because it doubles magnification some loss of apparent brightness is expected, though the fully multi-coated optics help preserve light transmission and maintain image clarity.
