Reticle eyepieces Illuminated crosshair eyepiece, Kellner 12mm

12mm Kellner cross-hair eyepiece, with illuminated double crosshair

The Omegon crosshair eyepiece is ideally suited for guiding astrophotos when used in off-axis guiders or guide scopes. The extremely fine, illuminated double crosshairs make tracking the guide star much straightforward for you. Instead of having to cover the star, as with single crosshairs, you can keep it precisely positioned in the centre of the eyepiece. Any deviation from this position is noticed immediately, and in time to be able to react.

The advantages in a nutshell

dimmable lighting, battery powered
eyepiece with clear optics for using faint guide stars
lens focusing - sharp focusing of the cross-threads for your vision
2x LR44 batteries included

Dimmable LED lighting with battery

The cross-hairs are illuminated with red LED lighting which can be dimmed by means of a rotary switch on the side. The eyepiece has adjustable dioptre compensation in order to be able to have both the star and the cross-hairs in focus.

Photos are not everything

Perfectly tracked astronomy photos are no secret, but the result of using the right accessories
