The Scientific Scientific eyepiece with a focal length of 20 mm has an incredibly wide, 100 ° field of view. In addition to the extremely wide field of view, it also has a comfortable retraction of the exit pupil, equal to 14 mm, which ensures comfortable observation also for people wearing corrective eyeglasses.

Thanks to the 9-lens optical system with lanthanum elements, it dramatically corrects chromatic aberration. Special EDM ( Enhanced Multilayer Deposition ) coatings on the surfaces of optical elements ensure high transmission of light.

A waterproof, waterproof and nitrogen-filled lens system prevents fogging of the optics even on high humidity nights.

Okular allows you to enjoy the perfect sharpness of images and spot images of stars in the whole powerful field of view.
