ABOUT LATEST 2X BARLOW LENS
Give your telescope eyepieces a 2x power boost! The Shorty 1.25-inch 2x Barlow Lens doubles the power of any 1.25-inch telescope eyepiece it is used with. For about the cost of a single eyepiece or less, the practical Shorty 2x Barlow effectively doubles the number of telescope eyepieces at your disposal.
MAIN FEATURES:
- Applies to all 1.25-inch interface telescopes
- Metal barlow magnification 2 times magnification
- Imaging clarity can be up to 15 times
- Apo design and multi-coated lens
- Full metal constructed and precisely CNC-machined
Optical Components -- The Real Physical Calculation Magnification
The 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 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 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!
Advantages of Latest 2X Barlow Lens
The 2X barlow lens body adopts precision CNC machining, and the internal thread design can eliminate stray light and reflected light, making the captured image clearer.
The housing is precision machined from aluminum stock and black anodized to a hard finish. The lens edges and inner barrel are blackened to provide maximum contrast.
This Barlow features an air-spaced, three-element, Apo design with fully multicoated optics which can effectively reduce reflected light, increase light transmittance, and provide you with brighter and clearer images.

Works just fine and as advertised. Works with my T-ring adapter with no problem.

I use it most nights I view and seems to be a good choice. I have not used any other product so I won't try to compare it.

I bought this Barlow lens not expecting much given the low price but I was pleasantly surprised. The item appears well built and the image it produces looks sharp across the field of view. I'm sure there is some degradation since a Barlow lens places more optics in the path, but I don't notice increased degradation.I am located on the East Coast, not the best place to observe planets and deep sky objects. So the weak link for me is the atmosphere. That may obscure any image degradation caused by the Barlow lens, but for me this was a great buy for the money.

Maybe it's my eyes but I did not see a 2x magnification with a 12.5mm eyepiece.

I have wanted a Barlow lens for a while, so got it with Mother's Day gift card money. I liked the price and The brand name is known among astronomers.

This 2x barlow is fine for what I bought it for, “lucky imaging†of the planets with my 8†Newtonian. It arrived quickly and was adequately packaged. Build and fit look good and performance is adequate for the task. I give it 4 stars because it works perfectly well in my system and for my purpose. YMMV.

The 2x Barlow works with eyepiece magnification, however, there was an unacceptable amount of purple fringe. I was unable to focus with the Barlow when attached to my Nikon dslr or Olympus mirrorless cameras by T-thread, which was attached to my Orion 80ST telescope, even with a 2 1/2-inch extension tube. Manufacturers description is all hype.

Stuff is bigger with it in. Smaller when it is not in.
