    QUICK-START GUIDE Step 1: Open tripod....and tighten lock ring. Step 2: Loosen vertical lock focus control. You may need to turn the focus knob 20 to 40 turns to focus your telescope for the first time. Always start observing using a low power eyepiece (such as a 25mm or 26mm eyepiece) to get a nice

    NOTE: Throughout this manual, you will notice the term "Alt/Az." Alt/Az stands for altitude-azimuth, which is just a fancy way of saying the telescope moves up and down, and from side to side. Not all telescopes move like this. Alt/Az alignment is just one of many methods used by amateur astronomers

The most common mistake of the beginning observer is to "overpower" his or her telescope by using high magnifications which the telescope's aperture and atmospheric conditions can not reasonably support.

    ADVANCED FEATURES Terrestrial Observing The ETX-80AT makes an excellent high-resolution, terrestrial (land) telescope. Viewing terrestrial objects image. If the image is fuzzy or ill-defined, reduce to a lower power eyepiece, where the heat waves do not have such an effect on image quality. Observing

    NOTE: The accuracy of One-Star Alt/Az Alignment, unlike the TwoStar Alt/Az Alignment procedure, depends on how well the observer levels the telescope and how close to North the telescope is pointed when setting the Home Position (Fig. 24). Because Two-Star Alignment uses two stars to align upon, it
