More product information
The Astro-Tech AT2XB achromatic 2x Barlow is physically quite short at 3.1” in length. This allows it to be used in the star diagonal of catadioptric and refractor telescopes to keep the eyepiece height comfortably low, as well as being used in reflector focusers,.

By doubling the power of each eyepiece it is used with, this Astro-Tech Barlow effectively doubles the number of 1.25” eyepieces in your collection. It uses a two-element, fully-multicoated optical system for excellent color correction and sharpness and works best at focal ratios of f/6 and above. The lens edges are blackened for maximum image contrast. The body is made of precision CNC-machined aluminum and is anodized for long life. A thumbscrew holds eyepieces in place.

Hi guys i have a eyepieces 25mm and a telescope with a length 1400mm
1400/25= 56 times but when i use this barlow 2x i will see 112times so you do not have to buy a another eyepieces and if you have another eyepieces like 4mm or 6mm or 8mm or 9mm or 10mm or 12mm or 17mm or 25mm or 32mm and you can you see how many times you can see like mine i have a telescope with a length 1400mm and then you can say for example 1400/10= 140x2 280 times you will see when you use this barlow it is genius. trust me
