  • Adjustable image and reticle focus and adjustable reticle brightness
  • Ideal for achieving accurate polar alignment and pointing accuracy

  • Five element, fully coated optics for excellent performance with faint stars
  • 50° Field of View (FOV), 20mm eye relief

The Agena illuminated 1.25” 24mm reticle eyepiece is the perfect accessory for refining the alignment and pointing accuracy of your goto telescope. Reticle eyepieces are essential for long exposure astrophotography where precise polar alignment is necessary. It is also required for centering guide stars in an off-axis guider (OAG) or guide scope. The Agena illuminated 1.25” centering eyepiece is priced significantly less than competitive centering eyepieces but performs these tasks as well or better than the competition.

20mm eye relief and soft roll-down rubber eyecup make this eyepiece a pleasure to use. The 24mm focal length provides a wide 50° apparent view of the sky allowing you to find objects and alignment stars more easily than shorter focal length eyepieces. Most illuminated reticle eyepieces have a short focal length and limited eye relief, which can make for uncomfortable viewing, particularly if you wear eyeglasses. The optical features of the Agena illuminated 1.25” reticle eyepiece virtually eliminate the need to swap out a typical high-power illuminated reticle eyepiece with a lower power eyepiece to locate or center objects.

The eyepiece reticle has a single etched crosshair precisely centered in eyepiece field of view for exceptional accuracy. A ring at the top of the eyepiece rotates to focus the crosshairs. The five-element optical system is fully multi-coated on all air-to-glass surfaces with high transmission anti-reflection coatings for bright, crisp views. The edges of the lenses are blackened for high contrast. The barrel is threaded for standard 1.25” astronomy filters.

The metal-body cordless red LED (light emitting diode) crosshair illuminator has a rotary on/off switch that also controls the reticle brightness level. Two 1.5V batteries (included) will power the illuminator for several hours of use. These GPA76 / LR44 model batteries are readily available when replacement is needed.

Note: Occasionally, the product you receive might have a slightly different cosmetic appearance or labeling than what is shown. This can often change from batch to batch according to the whims of the manufacturer. However, you will always receive a brand new, original product as described above.
