  • An astonishingly high-quality, immensely versatile Barlow lens that provides a 2x magnification boost to any 1.25" telescope eyepiece
  • For example: the Orion Shorty Plus 2x Barlow makes a 25mm eyepiece provide the same magnification as a 12.5mm eyepiece (25/2 =12.5)
  • Provides better eye relief and edge sharpness at a given magnification for a more comfortable view
  • Yields superior image sharpness and color correction compared to two-element Barlow designs
  • A great value - the Shorty-Plus Barlow essentially doubles the usability of each 1.25" eyepiece in your collection!

More Info

Besides doubling the power of any telescope eyepiece, this premium-quality 1.25" 2x Orion Shorty-Plus Barlow Lens features a 3-element, fully multi-coated lens design that renders exquisite views without introducing additional chromatic aberration, or false coloration. Images appear sharper and more color-correct than with standard, achromatic Barlow lenses. The Orion Shorty-Plus 3-Element Barlow Lens is especially good for high-power lunar and planetary observing and for boosting magnification refractor and reflector telescopes with relatively short focal lengths.

To double the magnification of any 1.25” telescope eyepiece, simple insert the eyepiece barrel into the Shorty-Plus Barlow and secure in place with the thumbscrew on the Barlow lens body. Place the combination of eyepiece and Barlow lens into the telescope focuser, adjust focus, and enjoy the doubly-magnified view. For example, using the Shorty-Plus Barlow with a 25mm telescope eyepiece installed will yield the same magnification as a 12.5mm eyepiece (25/2 = 12.5). Your resulting overall magnification value will depend on the focal length of your telescope.      

The Orion Shorty-Plus 3-Element Barlow Lens is conveniently compact for versatile use with many telescopes and as an added bonus, it’s petitie size makes it easy to stow in your accessory case. The Shorty-Plus 1.25” barrel is not threaded for use with telescope eyepiece filters.

I am a beginner star gazer and just purchased my first telescope. I called the tech department and they suggested the Shorty-Plus 3 lement Balow Lens for my telescope. After I recieved my Shorty-Plus 3 Element Barlow Lens ,I pop it in with the 10mm lensthat came with my Star Blaster 6iAnd found Jupitor ! It was crisp and clear. Without the lens I was unable to do this the day before.

I used this for 6 years, first to get a nice 100x eyepiece (20mm Ultrascopic) up to 200x with an SCT, which worked well for planets on still nights; and for brighter globular clusters, bringing out structures like the propeller in M13. The Shorty Plus also gave higher powers with 7mm to 15mm eyepieces in a small short tube refractor for study of the moon or quick looks at Jupiter and Saturn. I was happy with both uses and didn???t find any flaw in construction or views. A 1.25-inch extension tube between the Shorty Plus and the eyepiece gave higher power, closer to 3x. That got a 'short tube" scope into interesting lunar views.
After a sale provided a few new high power eyepieces I parted with the Barlow in favor of long eye relief, parfocal Radians that gave a practical high power range of 150x to 350x in the SCT, worked better with eyeglass wearers at outreach, and got the short tube up to 100x. Based on performance alone, I???d have kept the Shorty Plus, but 2x almost duplicated the only focal lengths available in my new eyepieces, so it found a new owner.
If you plan ahead when adding eyepiece focal lengths by the right steps, the high quality 2x Shorty Plus can extend an eyepiece set by giving more medium to high powers at little added cost - about the same or less than one eyepiece.
One unique aspect of the Shorty Plus is the very large clear aperture: the lens fills the front of the chrome barrel, with almost no recess into the barrel, and no aperture stop smaller than the barrel, like most Barlows. I believe that this helps avoid vignetting, which may be important with lower power or wider angle eyepieces and with shorter focal ratio scopes. But it also means you have to be careful to keep fingers away from the nicely multicoated lens.
I think some reviews may describe problems related to seeing, not optical quality of the Shorty Plus. A Barlow won???t give you a steadier night to go with twice the magnification. That???s why a Barlow that provides some added mid to high power choices, besides just the highest practical power, is the best supplement for visual use.
Pros: widest clear aperture; good optics
Cons: semi-exposed lens - be careful
Yes, I recommend this product!

If you want to get good views of Jupiter, Saturn and the moon, you will need this accessory. It doubles the magnification of the eyepiece. This one is nice and compact and provides very good views.
