Your SpaceProbe 3 EQ is a high-quality optical instrument designed for nighttime stargazing. With its precision optics and equatorial mount, you’ll be able to locate and enjoy fascinating denizens of the night sky, including the planets, Moon, and a variety of deep-sky objects. -
Page 4: Getting Started
Position the counterweight about halfway up the shaft Figure 2. The equatorial mount of the SpaceProbe 3 EQ. and tighten the lock knob. Replace the screw and washer on the end of the shaft. - Page 5 Figure 3. Proper operation of the equatorial mount requires balancing the telescope tube on the R.A. axis (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.

When the EZ Finder II is properly aligned with the telescope, an object that is centered on the EZ Finder II’s red dot should also appear in the center of the field of view of the telescope’s eyepiece. Alignment of the EZ Finder II is easiest during day- light, before observing at night. - Page 7 Dec. setting circle are negative.

This center mark is also required for best results with other collimating devices, such as Orion’s LaserMate Laser Collimator, obviating the need to remove the primary mirror and mark it yourself. NOTE: The center ring... - Page 13 Figure 9. To center the secondary mirror under the focuser, hold the secondary in place with your fingers while adjusting the primary screw with a Phillips head screwdriver. Do not touch the mirror’s surface. counter-clockwise will move the secondary mirror toward the primary mirror.
