TS Optics 2" Barlow Lens - 2.5x apochromatic 4-element design

The TS Barlow increases the magnification of your 2" or 1.25" eyepiece with the factor 2.5x. The premium 4-element optics is fully multi-coated for optimal brightness, high contrast and natural color imaging. The 4-element design allows the use even with very fast telescopes like f/4 Newtonians.

The Barlow lens has a high-quality workmanship. The four elements are mounted in a solid aluminium cell. At the inside, the Barlow is blackened as good as possible for avoiding reflexes when photographing moon and sun (only with solar filter).

1.25" and 2" accessories are locked by compression rings. Clamping is done gently and precisely on the optical axis.

At the telescope side, the Barlow lens offers a 2" filter thread where all common 2" filters can be screwed in.

Photography

This Barlow lens is a high-quality teleconverter at the same time, multiplying the focal length of the telescope with the factor 2.5x. The 4-element design ensures a very high sharpness on the axis and especially in the field. That is an important advantage against simple 2-element Barlow lenses. Even with full-frame sensors, you will achieve a good sharpness even to the edge.
