GSO 2x Barlow lens with T2 thread (1,25")

This 1.25" GSO Barlow is an Achromatic model, providing very small amount of chromatic aberration. In most of the cases its optical properties improves the image quality. The internal painting provides higher contrast compared to other models. Recommended from F/5 scopes.

An exceptional feature is that it provides a T2 thread on the eyepiece side. Using a DSLR makes the focal length approximately 2,5x times longer which might be ideal to image the Moon and planets.
