SkyView Deluxe EQ Mount Parts Diagram 2 Congratulations on your purchase of a quality Orion product. Your new SkyView Deluxe Equatorial Mount offers solid stability, mechanical precision, and the versatility to accommodate a variety of different small to medium-sized telescope tubes. [. . . ] Before clamping the rings tight again, rotate the telescope so the eyepiece is at a convenient angle for viewing (this is not possible if using a 1/4"-20 mounting adapter). Now when you loosen the lock lever on one or both axes and manually point the telescope, it should move without resistance and should not drift from where you point it. on the Dec. If you cannot see Polaris directly from your observing site, consult a compass and rotate the tripod so that the telescope points North. Polar Aligning Using the Polar Axis Finder One of the unique features of your new SkyView Deluxe mount is the polar axis finder scope. It fits conveniently inside the equatorial mount, and contains a tiny star map that makes precise polar alignment quick and easy. Approximately polar-align the mount as outlined in the procedure above. Remove the caps that cover the polar finder (one on the polar finder's eyepiece and one on the equatorial mount). If you have followed the approximate polar alignment procedure accurately, Polaris will probably be within the field of view. If it is not, move the tripod left-to-right, and adjust the latitude up and down until Polaris is somewhere within the field of view of the polar axis finder scope. Shine a red flashlight down the front end of the polar finder to illuminate the reticle within the field of view. Make sure the flashlight shines in at an angle, so as not to block the polar finder's field of view. It may be helpful to have a friend hold the flashlight while you look through the polar finder. Note the constellations Cassiopeia and Ursa Major (the Big Dipper) in the reticle (ignore the constellation Octans, as this is provided for Southern Hemisphere observers). They do not appear to scale, but they indicate the general positions of Cassiopeia and Ursa Major relative to Polaris and the north celestial pole (which is indicated by the cross at the center of the reticle). Next, the reticle must be rotated so the constellations depicted match their current orientation in the sky when viewed with the naked eye. You may need to reposition the telescope about the declination axis so the telescope does not bump the mount. Now, use the azimuth and latitude adjustment knobs on the mount to position the star Polaris inside the tiny circle marked "Polaris" in the polar finder's reticle. Turn the latitude adjustment knob and tilt the mount until the pointer on the latitude scale is set at the latitude of your observing site. If you don't know your latitude, consult a geographical atlas to find it. For example, if your latitude is 35° North, set the pointer to +35. The latitude setting should not have to be adjusted again unless you move to a different viewing location some distance away. lock lever and rotate the telescope optical tube until it is parallel with the R. A. [. . . ] You can't do it with the counterweight shaft pointing down as pictured in Figure 1. To point the telescope to the east or west, or in other directions, you rotate the telescope on its R. A. Depending on the altitude of the object you want to observe, the counterweight shaft will be oriented somewhere between vertical and horizontal. The key things to remember when pointing the telescope is that a) you only move it in R. A. [. . . ]
