The Orion Illuminated Plossl 12.5 mm eyepiece is a vital addition to any astronomer’s equipment collection thanks to its many useful applications.
Achieve precise alignment of computerized GoTo systems easily by using the relatively high-power 12.5 mm focal length eyepiece to accurately center alignment stars. The illuminated reticle enables you to precisely center alignment stars and objects in the telescope, thus increasing the accuracy of the GoTo system.
The 4-element Plossl design is also well suited for off-axis guiders, where light gathering is minimal, to help ensure tracking accuracy during guided astrophotography sessions. Use the 12.5 mm Illuminated Plossl with an off-axis guider (sold separately) to keep a guide star centered precisely to capture tack-sharp astrophotos.
A 4-element Plossl design with fully multi-coated lenses ensures bright views through the illuminated reticle eyepiece. Its 40° apparent field is ideal for multiple functions. The LED-illuminated double crossline reticle has adjustable focus and brightness. Three GP-189 batteries (included) are required for illuminator operation. Also compatible with three SR-54, SG-10, or equivalent button-cell batteries (not included). The Orion Illuminated Plossl 12.5 mm eyepiece features a 1.25″ barrel diameter, compatible with 1.25″ telescope focusers, or 2″ focusers equipped with a step-down 1.25″ adapter.
