TS Optics TSB251 apochromatic 2.5x Barlow Lens- 1.25 inch
A high quality Barlow lens for demanding visual and photographic use. The three-element apochromatic design offers an image quality virtually without any deterioration compared with a fixed eyepiece of the same effective focal length. The APO Barlow can be used on virtually any telescope. It is very short, so it will not usually collide with the mirror or prism in a star diagonal. The eyepiece or accessory are clamped with a brass compression ring to offer a solid lock without scratching the barrel.
The lens element
The three-element Barlow lens is fully multi-coated for a bright and high contrast image.
