Product Description

For the most accurate guiding possible, look no further than the Celestron Off-Axis Guider.  The Off-Axis Guider is the ultimate accessory for long focal length telescopes.  IT uses a prism to intercept a small portion of the focal plane in order to locate a guide star.  This relay allows any movement detected by the gudie star to be the exact movement seen by the imaging camera.  Guiding in this fashion allows for the correction of tracking errors or any mechanical failures or flexures.
