ongratulations on your purchase of a quality 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. -

(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. - Page 6 3. Retighten the counterweight lock knob. The telescope is retighten the R.A. and Dec. lock knobs.

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. - Page 8 Note : From this point on in your observing session, you remain stationary in the field of view without any manual should not make any further adjustments in the azimuth adjustment of the R.A. slow-motion control. or the latitude of the mount, nor should you move the tri- Understanding the Setting Circles pod.

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. - Page 11 it is very helpful to use a precision collimating tool containing crosshairs, such as the Orion Collimating Eyepiece (#3640). We highly recommend that you purchase one. Aligning the Secondary Mirror With the eyepiece removed, look straight down the open focuser drawtube at the secondary (diagonal) mirror. Ignore the reflections for the time being.
