Celestron CrossAim Reticle Eyepiece

The Celestron CrossAim is a 12.5mm focal length eyepiece housed in a 1.25" barrel. The eyepice is a superb accessory for precise polar alignment and can easily be used with off-aixs guiders for centering and guiding stars. The double crosshair reticle provides accurate alignment, particularly when used with the eyepiece's adjustable red LED light brightness controls. This preserves your night vision while still making the crosshairs easily to see. The fully coated optics are excellent for light transmission on faint stars. The Celestron CrossAim Reticle Eyepiece includes an illuminator to help you get the most accurate polar alignments.
