Threaded hole for tube connecting knob

Figure 17. The cast-metal dovetail trunnion on the left side panel of the base mates with the left side bearing of the telescope tube. Before mounting the tube on the base, turn the trunnion by hand so that the hole for the tube connecting knob is facing up.

Connecting the Optical Tube to the

Dobsonian Base

The telescope is now assembled and ready to be placed into the Dobsonian base. The left altitude hub on the optical tube has a dovetail slot that slides into the altitude axis trunnion on the inside of the left side panel (Figure 17). We recommend orienting the trunnion such that the threaded hole for the tube securing knob is facing upward. Then the telescope tube can be cradled horizontally and just lowered into the base by gen- tly sliding tube’s dovetail altitude hub into the mating recep- tacle of the altitude trunnion on the base (Figure 18). (Get help lifting the tube in place if it is too heavy or unwieldy for you.) The tube should now be resting in a balanced, horizon- tal position in the base. Then just insert and tighten the tube connecting knob to secure the tube in place (Figure 19).

Accessory Installation

Now that the base is assembled and the optical tube installed all that remains is to attach the EZ Finder II reflex sight and the eyepiece. These accessories can be found in a small box within the optical tube assembly box.

EZ Finder II

Using the included dovetail mounting bracket, the EZ Finder

IIwill slip neatly into the dovetail base preinstalled on your SkyQuest optical tube. The EZ Finder II arrives pre-installed in the mounting bracket. Just simply slide the dovetail mount- ing bracket into the telescope’s dovetail mounting base and tighten the thumbscrew on the base to secure the mounting bracket.

Operating the EZ Finder II

The EZ Finder II works by projecting a tiny red dot (it is not a laser beam) onto a lens mounted in the front of the unit. When

Figure 18. Hold the telescope tube as shown, with one hand on the rear end ring and the other cradling underneath the tube, gently lower the scope so the dovetail side bearing on the tube seats in the metal trunnion on the left side panel.

you look through the EZ Finder II, the red dot will appear to float in space, helping you to pinpoint your target object. The red dot is produced by a light-emitting diode (LED) near the rear of the sight. A 3-volt lithium battery provides the power for the diode. Turn the power knob (see Figure 20) clockwise until you hear the “click” indicating that power has been turned on. Look through the back of the reflex sight with both eyes open to see the red dot. Position your eye at a comfortable distance from the back of the sight. In daylight you may need to cover the front of the sight with your hand to be able to see
