Orion telescope. Your new SpaceProbe 130mm EQ is designed for high-resolution viewing of astronomical objects. With its precision optics and equatorial mount, you’ll be able to locate and enjoy hundreds of fascinating celestial denizens, including the plan- ets, Moon, and a variety of deep-sky galaxies, nebulas, and star clusters. -

Figure 4a, 4b, 4c, 4d. Proper operation of the equatorial mount requires that the telescope tube be balanced on both the R.A. and Dec. axes. (a) With the R.A. lock knob released, slide the counterweight along the counterweight shaft until it just counterbalances the tube. (b) When you let go with both hands, the tube should not drift up or down. -

By loosening or tightening the alignment thumb screws, you change the line of sight of the finder scope. Continue making adjustments to the alignment thumb screws until the image in both the finder scope and the telescope’s eyepiece is exactly centered. -

the Earth’s rotational (polar) axis—a process called polar alignment. Little Dipper (in Ursa Minor) Polar Alignment Big Dipper (in Ursa Major) For Northern hemisphere observers, approximate polar N.C.P. alignment is achieved by pointing the mount’s R.A. axis at Polaris the North Star, or Polaris. It lies within 1° of the north celes- tial pole (NCP), which is an extension of the Earth’s rota- tional axis out into space. - Page 9 Dec. = 0° mark are negative. telescope should be moved only on the R.A. and Dec. axes. So, the coordinates for the Orion Nebula listed in a star atlas To point the scope overhead, first loosen the R.A. lock knob will look like this: and rotate the telescope on the R.A.

Collimating the optics. (a) When the mirrors are properly aligned, the view down the focuser drawtube should look like this. (b) With the collimation cap in place, if the optics are out of alignment, the view might look something like this. (c) here, the secondary mirror is centered under the focuser, but it needs to be adjusted (tilted) so that the entire primary mirror is visible.

Your SpaceProbe 130mm EQ telescope requires very little mechanical maintenance. The optical tube is steel and has a smooth painted finish that is fairly scratch-resistant. If a scratch does appear on the tube, it will not harm the tele- scope. -
