Telescope moves off a terrestrial object while observing:

•Verify that the vertical and horizontal locks have been tightened to a "firm feel" (6 and 9 Fig. 1).

Telescope pauses when changing slew direction:

•This pause is normal.

A terrestrial object appears reversed left-for-right:

•An eyepiece in the standard 90° observing position (3, Fig. 1) yields this image orientation. To view a correctly oriented image, the optional #933 Erecting Prism is required. See “OPTIONAL ACCESSORIES,” page 25.
