Specialty eyepieces are eyepieces that are used for more than observing. 

Reticle eyepieces provide a magnified field with a crosshair pattern located inside the eyepiece.  These models can either be battery operated or connected to your telescope’s power source, and they may be illuminated.  Reticle eyepieces are used for acquiring and centering stars for GoTo system alignment, lining up guide stars and target objects for astro-imaging, and testing the accuracy of your tracking system.  They are also useful for centering an object before switching to a high magnification eyepiece.

An astrometric eyepiece is a high precision eyepiece for a wide range of astronomical measurements.  They are designed for measuring double star angular separations, position angles, planetary diameters, and lunar crater diameters, as well as many other useful astronomical measurements.  An astrometric eyepiece can also be used as a guiding and centering device.
