Description

The Levenhuk ED-3x Barlow lens is an optical accessory for increasing the magnification of the telescope threefold. It has a standard 1.25" barrel diameter, so that it is compatible with most modern telescopes. Due to its extra-low dispersion optics and full multi-layer coating, the Barlow lens delivers high quality images without distortion, and allows you to explore the night sky without chromatic aberration.

The lens features the filter thread that expands its field of application. The use of color filters (planetary, lunar and for deep sky objects observations) makes space exploration more exciting.

Questions and Answers

Sheila Curry (2016.01.31)

Could you clear one thing up for me? I've heard somewhere that if you insert Barlow lens directly into focuser and then install diagonal prism and eyepiece, you can obtain a larger focal length than if you insert Barlow after diagonal prism. Is it true?

Customer service:

Yes, that is true, the difference, though, won't be significant.

Leon Harris (2015.03.30)

Is this lens suitable for Levenhuk Ra 200N Dob? Can I get magnifications around 500-600x with it?

Customer service:

The highest practical power of Levenhuk Ra 200N Dob Telescope is 400x, there is no sense in increasing it further as it will only reduce image quality - the images will be blurred.

Jim Edwards (2014.06.12)

Should I insert this lens into the eyepiece?

Customer service:

Yes, the eyepiece should be placed in the Levenhuk ED 3x Barlow lens.
