Tele Vue Barlow 3x (1.25")

Due to high demand and global product shortages due to the pandemic, please call for availability.

The Tele Vue 3x 1.25" Barlow is a top-quality lens designed to tripple the magnification of any eyepiece. Simply insert the eyepiece into the top of the 3x Barlow, and get an instant power boost.

Tele Vue insists on nothing less than the best fully multicoated optics, using high-index glass to deliver the highest light transmission and best contrast of any Barlow, with less off-axis false color than 3-element Barlows.

The focal length of the eyepiece is divided by 3, so a 25mm eyepiece becomes 8.3mm. The field of view is also divided by 3.

Many astronomers prefer using lower-powered eyepieces with a Barlow to higher-powered eyepieces, due to being more comfortable to work with.
