Meade Off-axis Guider #777
Off-Axis Guider #777 (requires a T-mount). 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. Like the T-Adaptor 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 postion can be examined for tracking errorswith an illuminated reticle eyepiece; postion corrections can then be effected using the telescopes hand controller of drive corrector.
