Crosshair eyepiece - 12mm focal length - four elements - illuminated

This eyepiece is based upon a 12.5mm Plössl. Good field definition and comfortable viewing position make this eyepiece a good solution for a sensible price.

The illumination is continously variable in order to adapt it to the guide star's brightness.

Our hints for use:

For guiding, we recommend you to position the eyepiece in that way that one crosshair is parallel to the R.A. motion.
You can reach this by slewing the mount back & forth in R.A. and turn the eyepiece until the star runs inside one parallel section.
Now you can see immediately while guiding if the guide star "escapes" in R.A. or Dec. and perform the right corrections.
