Product Description

Size: 1.25 in.

Double your pleasure! Celestron's Omni, 1.25-inch, 2X Barlow lens is on everyone's list of absolute must-have accessories. A very good entry-priced Barlow, it will make quite a difference in your telescope's performance. The Barlow lens doubles the magnifying power of any eyepiece it's used with. For example, an 18mm eyepiece used with a 2X Barlow lens would have the magnifying power of a 9mm eyepiece. And on a telescope with, say, 1,500mm focal length, magnification would jump from 83X without the Barlow to 166X with it. It's like having two eyepieces in one! No wonder folks like them: they can instantly double their eyepiece collection. 2x Barlow Lens that doubles magnification. 1.25 inch format design. For use with all 1.25 inch eyepieces. Low profile, 2-element design. Fully-Multicoated optical design with blacked lens edges.

I picked up a Celestron 21024 3" tabletop reflector, hoping to get my feet wet in backyard astronomy. The scope actually turned out quite nice, but with its short focal length, the effective magnifications even with a 4mm eyepiece were pretty low. I tried some other barlow eyepieces, none of them would even focus.
The Celestron Omni barlow worked great on that telescope, and I was actually able to make out the bands on jupiter using the barlow, a 12.5mm plossl, and the celestron 21024. I was pretty surprised. If you have the celestron 21024, you'll want this barlow.

I am new to astronomy so I went out on a limb and purchased this Barlow lens for my Celestron 80mm EQ Refractor. It works well. Keep in mind the lens seems to let in less light but I could see Mars, Saturn, the Orion Nebula and several star clusters with good clarity. I only have 10mm and 25mm eyepieces and this doubles my set. I live in an area with terrible conditions for backyard astronomy but this piece has brought out a few more objects. Next I'll try some Celstron Omni eyepieces.

I just purchased an Orion 8 inch telescope--without the barlow Saturn's rings are nearly invisable when I use just the eyepiece that came with the scope. When the barlow is attached Saturn becomes amazing! I love this product and am considering purchasing a 4x to see what the difference is--I recommend this lens highly.

I've been an amateur astronomer for over 25 years. This is a great barlow and the first time I've used one. My wife and I used this in our 6" f5 Celestron Reflector (f/l 750mm). It provided great views with a 26mm lens inserted into the barrel of the Ring Nebula (M57), Andromeda Galaxy (M31), and several other deep sky objects. Even the moon looked great! With the 5mm lens, which was probably overkill, made us feel as if we were right on the moon itself. Of course, when jacking up the magnification this high the image quality isn't as great or as sharp (this is normal when using higher power). For the price, this is an awesome item! Can't wait to get the 3x version.

Users who don't know what they are doing, or talking about, is really getting on my wick. It could be a review on spoons or the latest electronic device, but this explains the long amble to my final remarks on the Celestron 2x Omni Barlow in this review.

Observational astronomy has been my avocation for 33 years with hundreds of dusk to dawn sessions, and thousands of hours at the eyepiece.

I am afraid that most people who purchase a Barlow lens have performance expectations that are naive, or are trying to correct the mistake of having purchased a telescope whose f/ratio is so low as to make any high magnification observations disappointing. An f/4 telescope is fine for observing deep sky objects in a wide field of view. An f/15 refractor is best suited for planetary, lunar and binary star observations where high magnifications and high contrast images are required.

As we move through a range of eyepieces from low to high power what does the user notice most? It is the eye relief. The eye relief of a 32 mm is long enough even to use glasses. But as we drop down to 6 mm, 5 mm, and 4 mm the eye lens becomes very small. You must move in so close as to sometimes touch the eye lens with one's eye lashes. If you wear glasses, they must be removed to get close to the eyepiece. Now any malady your eyes suffer from are uncorrected. This may introduce chromatic aberrations, serious astigmatism, &etc, to the telescopic image.

Of course there is the telescope itself. The best instruments under good atmospheric conditions can, at best, employ 50x to 60x (power) per inch of aperture. Further magnification is called "empty magnification". Why? Because you have already reached the theoretical resolution limit of the telescope. More magnification reveals no more detail.

I bought this 2X lens to complement my Celestron C70 Spotting Scope for target shooting. It is an excellent product and exceeded my expectations. Shipping was prompt and reasonable and I will continue to be an Amazon customer.

Bought this because the 3x barlow that came with my powerseeker 70 was a piece of crap. This is a lot better quality and much more useable than the 3x was.
