Reticle eyepieces Illuminated crosshair eyepiece, Plössl 9mm

 

Cross-hair eyepiece with adjustable double filament - great for an off-axis guider

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

• adjustable double crosshairs - particularly suitable for an off-axis guider

• 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

Steplessly adjustable cross-hairs

Sometimes the guide star is not in the centre but rather at the edge of the field of view. This is especially tricky when using an off-axis guider. Adjusting the image field is out of the question. But this model lets you move the cross-hairs in any desired direction.

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.

9mm Ploessl design

The 9mm Ploessl eyepiece offers a very high magnification. This is good for a fast reaction in case of any tracking deviations with the guide star.

The four lens element design provides a clear and sharp image. Multi-coating ensures high transparency, so that you can make out faint guide stars too.

 

Photos are not everything

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