Meade #777 Off-Axis Guider Body
The Meade #777 Off-Axis Guider provides a means, during long-exposure astrophotography, for the photographer to monitor the tracking of the telescope, to assure that the telescope remains precisely positioned on the object being photographed. Like the T-Adapter, the Meade #777 Off-Axis Guider couples a digital or film SLR camera body to the telescope but it also causes a small amount of the guide star’s incoming light to be diverted at a right angle, where the star’s position can be examined for tracking errors with an illuminated reticle eyepiece. Position corrections can then be effected using the telescope’s hand controller or drive corrector.
Also needed is an illuminated reticle eyepiece, a T-ring to attach your SLR camera body to the guider, and, of course, the camera and telescope (all of which are sold separately).
