Attach the universal mounting base to the tube with the two screws and secure by threading a lock washer and hex nut onto the threaded end of the screw. The threaded ends of the screws should be on the inside of the telescope tube. Instead of screws, the double-sided foam tape can be used to attach the universal mounting base to the telescope tube. [. . . ] Slide the EZ Finder II onto the bracket and tighten the two thumbscrews (See Figure 1). Then simply slide the dovetail mounting bracket into the telescope's dovetail mounting base and tighten the thumbscrew on the base to secure the mounting bracket. To install the EZ Finder II on other brands of telescopes Use these instructions to mount the EZ Finder II on other brands of telescopes, custom telescopes, or when you wish to mount the EZ Finder II in addition to your regular finder scope on an Orion telescope. To attach the EZ Finder II, you will need to attach the included universal mounting base to the telescope. You can attach this by using the double-sided foam tape (recommended for refractors) or with the two included screws. In order to attach the universal mounting base with the screws, you will need to drill holes in the telescope tube. Lay the template on the telescope tube so that the long axis is parallel with the long axis of the optical tube. Poke a pencil point through the center of each hole, marking its position on the tube. Use a #25 (. 148") or similar drill bit and drill two holes where the pencil marks are. Base template for drilling holes (actual size) Figure 2. IN 182 Rev A 03/02 Operation The EZ Finder II works by projecting a tiny red dot (it's not a laser beam) onto a lens mounted in the front of the unit. When you look through the EZ Finder II, the red dot will appear to float in space, helping you locate even the faintest of deep space objects. The red dot is produced by a light-emitting diode (LED) near the rear of the sight. Turn the power knob (see Figure 1) 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 the dot, which is purposefully quite dim. For best results when stargazing, use the dimmest possible setting that allows you to see the dot without difficulty. [. . . ] Then slide the new battery under the battery lead with the positive (+) end facing down and replace the battery casing. Specifications Weight: Length: 2. 8 oz. (with dovetail mounting bracket) 4-3/4" Magnification: 1x Field of View: 10° Light Source: Power: light-emitting diode (LED) 3-volt lithium battery Aligning the EZ Finder II 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 daylight, before observing at night. [. . . ]
