Product Description

Give your telescope eyepieces a 2x power boost! The Orion Shorty 1.25 inch 2x Barlow Lens doubles the power of any 1.25 inch telescope eyepiece it's used with. For about the price of a single eyepiece or less, the practical Shorty 2x Barlow effectively doubles the number of telescope eyepieces at your disposal. The Orion Shorty 2x Barlow Lens doubles the magnifying power of any 1.25 inch eyepiece, essentially dividing the eyepiece's focal length by a factor of 2. For example: using a 25mm eyepiece in the Shorty 2x Barlow provides the same magnification a 12.5mm eyepiece would normally exhibit (25 / 2 = 12.5). Using this simple formula, you can easily determine how each of your 1.25 inch telescope eyepieces will perform when inserted in the Shorty 2x Barlow Lens. A 20mm ocular will behave like a 10mm eyepiece; a 6mm eyepiece will provide the magnification of a 3mm eyepiece, and so on. Using the Orion Shorty 1.25 inch 2x Barlow Lens is easy. Simply insert the Shorty 2x Barlow into your telescope's focuser or diagonal, and then insert any 1.25 inch eyepiece into the Orion Shorty, gently securing it in place with the two thumbscrews. Then, adjust the telescope's focus wheels to enjoy double the magnification of the eyepiece used. Think of the money you can save with this practical and affordable telescope eyepiece accessory! 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, the Shorty Barlow can also make observing at high powers more comfortable. Many low focal length high-power eyepieces have a woefully small eye lens that can be troublesome to peer through, especially for eyeglass wearers. Using the Orion Shorty 2x Barlow Lens with a longer focal length eyepiece lets you achieve the same high magnification view, but in most cases the eye lens will be much larger, helping to reduce eye strain and improve comfort.

As for construction this feels like good quality and is very clear!

This barlow works as expected: it doubles the magnification of your eyepieces.

I now can see the rings of Saturn clearly along with Jupiter's four moons.

I picked up this Barlow lens after reading that Barlow lenses were must haves for any telescope kit because they basically double (in theory) the amount of eyepieces you have. For anyone who doesn't know how they work, you simply slide the Barlow lens into your eyepiece slot like a normal eyepiece, and then your normal eyepiece will slide into the Barlow. So in essence, if you have 2 eyepieces, with the Barlow lens you now have 4. The magnification boost that the Shorty gave to my .10mm and .17mm eyepieces was pretty incredible to say the least. I use a Konus 4.5" reflector telescope and with the Barlow boosting my .10mm eyepiece Saturn looked absolutely stunning. You could see the divisions inside the rings, something that was not easily done with the eyepieces alone. Another very convenient thing is that the Shorty can be swapped out just as fast as any normal eyepiece. That being said, I would find the object I was looking for with the wider viewed .17mm eyepiece, then just swap out that one with the .10mm Barlow-loaded eyepiece and the object would be in the center of my FOV within a few seconds. Long story short, if you want some extra magnification power for your eyepieces, look no further. At first I was a bit skeptical that the magnification boost wouldn't be very noticeable, but I was pleasantly surprised at just how well it really worked. For the price, you can't beat it.

Pros:
-----
Doubles your lens collection. My son has a 90mm mak-cass. He has two lenses that yield 50X and 75X. The barlow doubles them to 50X, 75X, 100X, 150X. This is about as large as a 90mm can go.

I use this barlow on my Dobsonian. I like having more magnification without reducing the exit hole on my eyepiece. Some eyepieces are not as good around the edges. A barlow gives a larger clear spot while increasing magnification. This is win/win. I often use the barlow, even if I have a lens that will yield the same magnification.

Cons:
-----
A barlow will give good magnification on items that can be magnified, such as the moon and planets. When looking at deep sky objects, I often like wider fields and lower magnification.

This particular barlow offers great bang for the buck.

This will be a good product for most applications, and is very convenient for lighter scopes. Works just fine in my Meade ETX-90. But shows its weakness, as all less expensive eyepieces do, in a very high quality refractor (Stellarvue SV80S). Consider the short Antares 3X Barlow, or the more expensive Orion 2X, if you have a scope with very hiqh quality optics, or might upgrade to it.

I got one of these for my StarBlast 4.5EQ and I was amazed--the Cassini division and cloud bands on Saturn were opened to my view. Highly recommended for getting that last bit of "oomph" from a small telescope.

First of all, judging by some of the negative reviews, I think some folks are expecting too much from the benefits of a Barlow -- it's not a cure-all, and it's not intended to achieve super-magnification, and will only serve to disappoint in poor observing conditions (i.e., light polution or unsteady skies). The use of a Barlow with a high power eyepiece, so you can see rocks on the Moon is pure folly -- when pushed too far, the use of a Barlow will only render fuzzy images. They're fine when coupled with a 25 or 30mm eyepiece, but if you try doubling the power of a 10 or 12mm, you're only asking for disappointment, unless you observe from a mountain top.

By the way, using a Barlow will preserve the Eye-Relief of the eyepiece its coupled to. So 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.

The Orion Shorty PLUS was my first Barlow -- in 1997. I purchased it along with a 30mm Ultrascopic eyepiece, which today is considered among the best in the world for clarity and contrast, but after '99 was downgraded with cheap glass, and manufacturing was shifted from Japan to Taiwan, resulting in overpriced junk. This Barlow is NOT the Shorty Plus, (which was made in Japan with excellent glass) but it's almost as good.

The Shorty Plus Barlow and that Ultrascopic have seen duty together hundreds of times, and have given me countless gratifying moments and images. In 2007, I replaced it with a Televue 2x, but I must say, that the Orion Shorty Plus holds its own by comparison. Yes, the Televue is noticeably better in very good skies and conditions, but those conditions don't present themselves very often.

This barlow lens works fairly well and I would recommend it for someone starting out on a limited budget and may not have the ability to purchase mulitple eyepieces in order to achieve different magnifications. As many books, magazines, reviews mention a barlow will double the capacity of an existing set eyepieces at the cost of a single eyepiece.

This barlow lens multiplies the magnification provided through a telescope by a particular eyepiece by two. So if you have a 20mm eyepiece the barlow will make it behave like a 10mm eyepiece. Also the user should be mindful that high magnification competes against image quality particularly around 200x in most cases primarily due to atmospheric conditions, so doubling an eyepiece that already proivdes 150x may not provide as good a quality image than doubling one that provides 90x even though the doubled 150X to 300x image will be larger. There are those rare clear nights one can try to achieve higher magnifications, but where I live Northern Virginia those are few and far between.

Ergonomically a barlow lens lengthens your eyepiece out of the back of your telescope focuser, this model being a "shorty" does a fair job of making a barlow eyepiece combination less unweildy. Image quality through this barlow lens is decent, though now having acquired numerous eyepieces (over a ten year period) I tend to favor single eyepieces which produce high magnification in favor to a barlow combination with lower power eyepiece, since I am looking through less lens elements for the same or similar resulting magnification.
