Hyperion Universal Zoom Mark IV: fourth generation of Baader-Zoom, 68° Widefield eyepiece with five magnifications - focal lenghts 8, 12, 16, 20 and 24mm clearly defined with "smoothed-out" improved Clickstop Action (a must for effortless binoviewing) Description Hyperion Mark IV Universal Zoom 8-24mm Eyepiece with 1¼" / 2" nosepieces and ClickStop-Action Zoom-lenses in general are not really famous for high quality optics.

The recognition...
