Is the Celestron 93326 Omni Barlow Lens Worth It in 2026?

Is the Celestron 93326 Omni Barlow Lens Worth It in 2026?

Per Celestron's own product page, the Omni 93326 is a 2x Barlow lens that doubles the magnification of any 1.25-inch eyepiece you already own while keeping that eyepiece's original eye relief -- so it's worth it specifically if you want more magnification from your existing eyepieces without buying new ones. It is not a new eyepiece on its own, and it only fits 1.25-inch focusers and eyepieces, per Celestron's page.

What a Barlow Lens Does, Per Celestron's Own Description

Celestron's page describes the Omni 2x Barlow's job in two sentences: "Double the magnification of each eyepiece you own with the Omni 2X Barlow Lens," and "Keep the eye relief of your eyepieces while getting 2X the power." In practice, a Barlow sits between the focuser and the eyepiece and increases the telescope's effective focal length for whichever eyepiece is inserted; since magnification equals the telescope's focal length divided by the eyepiece's focal length, doubling the effective focal length this way doubles the magnification that same eyepiece produces -- which is Celestron's own "double the magnification" claim, stated differently. The second sentence matters for comfort: ordinary ways of getting more magnification (switching to a shorter-focal-length eyepiece) usually mean a tighter, less comfortable eye relief, which is the "keeps the eye relief" benefit Celestron's page is describing.

The Amazon listing for this exact item describes it simply as "Celestron 93326 Omni Barlow Lens, Silver, 2 x 1.25 Inch," matching Celestron's own 2x magnification and 1.25-inch barrel figures.

How the Doubling Actually Works

Because a 2x Barlow doubles the telescope's effective focal length for whatever eyepiece sits in it, the practical effect scales with the eyepiece you already use: the same eyepiece now sees double the effective focal length behind it, which -- per the magnification formula above -- reads as double the original magnification through that same eyepiece. Celestron's page states the Barlow "accepts 1.25" eyepieces," so any 1.25-inch eyepiece you own is a candidate; the gain in magnification is the same 2x multiplier regardless of which specific eyepiece you pair it with, per Celestron's own description of the lens. This also means the Barlow's effect is consistent across a whole eyepiece case: swapping in a different 1.25-inch eyepiece changes the starting magnification, but the Barlow still doubles whatever that starting number is, per the same fixed 2x figure Celestron states for this item.

The filter threads Celestron's page lists mean standard 1.25-inch filters can thread onto the Barlow itself, ahead of the eyepiece, which keeps a filter in the optical path without needing a separate thread on each eyepiece you own.

Why a Barlow Instead of More Eyepieces

A 2x Barlow effectively doubles the number of distinct magnifications available from whatever eyepieces you already own, since each eyepiece now produces two results: its own stated magnification, and that figure doubled with the Barlow inserted. Per Celestron's page, the multiplier is fixed at 2x regardless of which 1.25-inch eyepiece is used, so a two-eyepiece kit becomes four usable magnifications rather than two, without buying a third or fourth eyepiece outright. That's a different trade-off than buying another eyepiece directly: a new eyepiece adds one specific magnification at its own cost and takes up its own space in a case, while this Barlow adds a second magnification to every eyepiece already owned, and it travels as one additional accessory rather than several.

Fit and Compatibility

Celestron's page is specific that this Barlow "slides into 1.25" focusers and diagonals" and "accepts 1.25" eyepieces." That cuts both ways: if your focuser, diagonal, and eyepieces are all 1.25-inch, this Barlow fits directly, per Celestron's own stated compatibility. If any part of your setup is the larger 2-inch size, or an older 0.965-inch size some vintage and low-cost scopes use, Celestron's page doesn't describe this Barlow as fitting those, and neither the listing nor Celestron's page mentions an adapter for either size. Checking your own focuser and eyepiece barrels against the 1.25-inch figure before buying is the one compatibility step this page can't do for you.

What Stands Out

• It doubles magnification without buying new eyepieces. Per Celestron's page, the same 2x multiplier applies to whichever 1.25-inch eyepiece you already own.
• It's built to preserve eye relief, per Celestron's own stated benefit -- a real comfort difference compared with simply switching to a shorter eyepiece for more power.
• The optics are two elements, fully multi-coated, per Celestron's page, rather than a single uncoated lens.
• It's small and light at 2.11 ounces (60 g), per Celestron's stated weight -- an easy addition to an existing eyepiece case.
• Filter threads are built in, per Celestron's page, so standard 1.25-inch filters still have a place to attach.

Where It Might Not Fit

• It only fits 1.25-inch hardware. Celestron's page describes fit with 1.25" focusers, diagonals, and eyepieces specifically -- not 2-inch or 0.965-inch equipment.
• It only ever doubles whichever eyepiece you already own. If you want a specific magnification that isn't exactly double one of your existing eyepieces, this Barlow doesn't substitute for simply buying an eyepiece at that focal length.
• Neither Celestron's page nor the Amazon listing states a warranty term or an included case for this specific item.

How It Compares to Other Eyepiece Gear on This Site

For a broader look at which eyepieces -- and whether a Barlow -- to add first, this site's eyepiece-upgrade guide walks through a beginner's first additions in more depth than a single Barlow review can. And since doubling magnification matters most on small, bright targets, this guide to picking a telescope for planetary viewing is a useful companion read for anyone buying this Barlow specifically to push magnification higher on the Moon or planets.

Verdict

The Omni 93326 is worth it for a narrow, specific job: doubling the magnification of 1.25-inch eyepieces you already own, with the eye relief of those same eyepieces preserved, per Celestron's own description. Check the current price of the Celestron 93326 Omni Barlow Lens on Amazon if your eyepieces and focuser are 1.25-inch. It's not a substitute for owning more eyepieces outright, and it only helps directly if your eyepieces and focuser accept 1.25-inch hardware -- some 2-inch focusers ship with a step-down adapter (Celestron's own StarSense Explorer 8" Dobsonian is one such telescope, per its own product page) that lets a 1.25-inch Barlow like this one work anyway, so check your own setup's adapter situation rather than assuming by focuser size alone.
