  • Quality aluminum stock and black anodized body with M42x0.75mm Thread: Work as a T-adapter; connect DSLR or SLR camera to telescope easily via a separate sale T ring adapter
  • Double the power of 1.25 inch telescope eyepiece with the Barlow Lens for 1.25 inch eyepieces from Celestron; Orion; Sky-Watcher; Meade and most brands of telescope; filter thread for any 1.25 inch filter
  • 85mm focal length; reduction factor of about 0.5x; depending on spacing; 0.5x focal reducer effectively halves the focal length of a telescope; enabling lower magnification with a wider field of view; and shorter exposure times for astrophotography
  • Comfortable observation with 90 degree: Look pleasantly from above into your eyepiece; filter thread for any 1.25 inch filter and accepts standard 1.25 inch eyepieces
  • Made of genuine optically processed BK7 glass; premium optical prism inside rather than mirror which makes image clear and sharp; amici prism looks as beautiful as binoculars; but you can zoom in much higher with your eyepieces

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

6

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.

7

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.

8

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.
