Omegon Cross Thread Eyepieces - Eyepiece with illuminated double reticle
The Omegon Crosshair eyepiece is perfect for astrophotography and precision work. The 12mm eyepiece has an extremely fine, illuminated double reticle that allows you to easily center tracking stars. You no longer need to cover the star as with a single reticle, and small position changes are immediately visible.

Advantages of this eyepiece
Clear optical image for faint tracking stars. Adjustable reticle focus for your eyes. Runs on 2x LR44 batteries (not included). Accurately measure image fields or align a mount with the Pole Star. Easily determine the positional angle of double stars. This eyepiece is not only useful for astrophotography, but also a useful tool for aligning your telescope and measuring objects in the field of view.

Practical and versatile
This eyepiece is not only useful for astrophotography. It is also a useful tool for aligning your telescope and measuring objects in the field of view. Perfect for both beginners and advanced amateurs who value precision.
