Mead 777 OFF-AXIS Guider For LX Series 7054 add comments
Description
The 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 Guider couples the camera body to the telescope but it also causes a small amount of the guidestar 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.
