The 5 Best 2.5 x Barlow Lens (2023 reviews)

Not everyone likes to purchase len for their regular usage, but the orion 2.5 x barlow len would be an anomoly. If you wear glasses, a Barlow saves you from having to use a short focal length eyepiece (with short Eye Relief) to double the power. This Shorty helps the planets look a bit bigger, and much more detailed. It magnifies your view without any sacrifices. This will work with any telescope that uses a 1.25" eyepiece. It is perfect for any amateur astronomer.

Not only does the orion shorty 2x barlow's power-boosting ability mean you can enjoy two different viewing magnifications with each 1.25 inch telescope eyepiece in your collection, but the shorty barlow can also make observing at high powers more comfortable. The increased magnification makes finding small objects like planets much harder with the NexImage. This lens is supposed to double the magnification of any given eyepiece it is used with a 1.25" eyepiece.

Why We Like This:

Fringe and works with two different zwo cameras
Excellent piece of hardware to have
Very clear, good fov, doesn't significantly reduce apparent brightness, good mechanical fit

Best For many eyepiece attachments: Celestron 2.5 x Barlow len

Buy on Amazon

The celestron 2.5 x barlow len's superior materials makes sure that it ages well with use. It makes a very basic telescope much more useful. It is an excellent Barlow lens. When you put this barlow in, the lens takes the last few cm of that cone and stretches it, lowering that angle, so your scope acts as if it is twice as long with the same size mirror/objective lens, thus doubling its f number. The 1.25” barrel will fit in standard 1.25” focusers and diagonals, and the Barlow will accept 1.25” eyepieces. It is compatible with every scope that can take a 1-1/4" ep.

A nice touch on this is that you can unscrew the bottom and screw it right on an ep so you don't have to move the focuser as much to get it back in line.

Why We Like This:

Larger barrel, rubber hand grip, brass compression ring to safely grasp heavy eyepieces
Pairs well with the omni-series plössl eyepieces
New and hot release

Best with certain eyepieces: SVBONY 2.5 x Barlow len

Buy on Amazon

Next on the list, we've got yet another len that manages to win our hearts. It's the svbony 2.5 x barlow len and it's widely considered as one of the best convenient len you can buy. Looking at the moon with this and a 25mm eyepiece is great as tons of details can be seen than without it. It fits almost any standard 1.25" caliber eyepiece. You can use it directly as long as the meade instruments 209006 infinity 102 az refractor telescope is 1.25" caliber. It provides clearer images on the edge of field of view so it is easier to evaluate quality.

The Orion Starblast focal length is only 450mm and useful magnification is. It's advertised as a 3 element apochromatic.

Why We Like This:

Really good quality aluminum and lens
Viewing is very good, especially with lunar features
Good fit for short focal length reflectors
Great on planets but blurs more distant objects

Best For some focusing combinations with different eyepieces: Astromania 2.5 x Barlow len

Buy on Amazon

Not everyone likes to purchase len for their daily usage, but the astromania 2.5 x barlow len would be an anomoly. It is perfect for prime focus astrophotography. It allows the use of both 2" and 1.25" eyepieces. The barlow increases the magnification of any 2" or 1.25" eyepiece by two and a half times. Brass compression rings with knurled set screw grips securely hold eyepieces without marring the eyepiece barrel's finish. It is good for some focusing combinations with different eyepieces.

Why We Like This:

Fully multicoated optics, 4-element lens system
Hard-anodized aluminum barrel is threaded to accept 2" filters
Nice solid 2x barlow, good glass and works great
2.5 x magnification, anodized aluminum housing

Best For reflector telescopes: SVBONY 2.5 x Barlow len

Buy on Amazon

It's great for reflector telescopes. The Sv118 2x barlow lens provides a high power magnification that allows you to look more closely and more detailed at the moon's surface and other planet. The lens works great on both telescopes and gives sharp images up to 200x magnification. It is made of aluminum alloy material that has a long service lifetime. It is suitable for all astronomical telescopes that meet the interface dimensions;however, it should be noted that the magnification after matching with the barlow lens cannot exceed the effective magnification of the telescope, otherwise you may not be able to obtain a clear image.

This Barlow lens uses two-element, fully multi-coated for excellent transmission and the internal housing is baffled to eliminate unwanted reflections and increase contrast. The product is more textured and meets your exquisite requirements for the details of the appearance. It is great for reflector telescopes.

Why We Like This:

Fit and finish, a little heavier, because its just better
Fully coated fmc all glass achromatic
Just 2.5 inch long, easy to stash in your accessory case
