    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 3A, 3B, 3C, 3D. 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.

    Focusing the Finder Scope first the R.A. axis of the mount must be aligned with the Earth’s rotational (polar) axis - a process called polar alignment. If, when looking through the finder scope, the images appear somewhat out of focus, you will need to refocus the Polar Alignment finder scope for your eyes.

    6. Collimating the Optics Similarly, to point the telescope directly south, the counter- weight shaft should again be horizontal. Then you simply rotate (Aligning the Mirrors) the scope on the Dec. axis until it points in the south direction. What if you need to aim the telescope directly north, but at Collimation is the process of adjusting the mirrors so they are an object that is nearer to the horizon than Polaris? You can’t precisely aligned with each other.
