Now, sight Polaris in the polar axis finder scope. 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. lock lever and rotate the main telescope about the R. A. axis until the reticle is oriented with the sky. You may need to reposition the telescope about the declination axis so the telescope does not bump the mount. Once the reticle is correctly oriented, use the R. A. lock lever to secure the main telescope's position. 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. The pointer 5 the bolt that connects the equatorial head to the tripod. [. . . ] and Dec. , not in azimuth or latitude (altitude), and b) the counterweight and shaft will not always appear as it does in Figure 1. In fact, it almost never will! Tube Mounting Rings These quality cast-aluminum rings are custom-made for use with the SkyView Equatorial Mount. They are hinged for easy installation of the telescope tube and are lined with felt to prevent scratching of the telescope. Check the outer diameter of your telescope; if it matches the inner diameter (I. D. ) of the rings, then the rings will fit. [. . . ]
