The new Series 5000 TeleXtenders are the finest power multipliers sold today. Their advanced four element design delivers a flatter field of view with sharper edges than even the best 3-element apochromatic Barlows. They feature fully multi-coated lenses with no color fringing.

Features:
* Flat field of view
* Premium grade optical glass
* Individually tuned, multi-layered coatings for maximum light transmission and highest contrast
* Lens edges and all internal metal surfaces are blackened to maximize image contrast
* Maintain the comfortable eye relief of longer focal length eyepieces while increasing magnification.
