Opticron SDL v4 Zoom eyepiece

The Opticron SDL v4 zoom eyepiece is an improved version of the SDL v3. It stands out with a sharper and brighter image than its predecessor, while remaining similarly compact in size. We recommend this triple zoom eyepiece with its special professional quality for ED-lens Opticron spectra. The wide range of variable magnification allows for true universal use, whether it's scanning the surrounding landscape at low magnification or observing the feathers of a bird resting on a distant tree branch at close magnification. The usual high quality from Opticron ensures that this eyepiece will stand its ground in all fields of observation.

If you want to get the most out of your Opticron scope, the Opticron SDL v4 zoom eyepiece is the obvious choice! Comfort of use was a key consideration when designing the SDL v4 zoom eyepiece. You don't have to squeeze your eyes into this eyepiece. The viewing distance over the entire zoom range is large enough for even observers with glasses to see the entire field of view at high magnifications. The large 25 mm objective lens ensures that even long exposures don't tire the eyes. And the four-way adjustable eyecup lets you quickly set the viewing distance that's most comfortable for you.
