User manual ORION TELESCOPES & BINOCULARS 07084

[. . . ] EZ Finder has a wide 9° field of view, and now includes a quick-release dovetail base and adjustable brightness control. Brightness Control Operation EZ Finder 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 finder, 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) in the rear of the sight. [. . . ] The object should be a half mile away or farther. Now, with the On/Off switch On, look through EZ Finder. Hopefully, the object will appear in the field of view near the center dot. Now, without moving the main telescope, you'll use EZ Finder's azimuth (left/right) and altitude (up/down) adjustment controls to center the red dot on the object. Left/right movement is controlled by the Phillips-head screw located on the side opposite the On/Of switch. Up/down movement is controlled by the Phillips-head screw at the rear of the unit (see diagram). When the red dot is centered on the distant object, check to make sure the object is still centered in the telescope's field of view. If not, recenter it and then adjust EZ Finder's alignment again. When the object is centered in both fields of view, EZ Finder is properly aligned with the telescope. Once aligned the first time, EZ Finder will usually hold its alignment even after being removed and remounted on the dovetail base. Otherwise, only minimal realignment will be needed. Parts List 1 EZ Finder reflex sight with 3-volt lithium battery 1 Dovetail mounting base 1 Double-sided foam tape 2 3/8" flathead 6-32 bolts 2 3/4" flathead 6-32 bolts 2 Lock washers 2 Hex nuts Installation First, open the box and make sure all the parts are present. The base can be attached to the telescope tube with the double-sided foam tape (recommended for refractors) or with two bolts. For your convenience, we have provided two pairs of bolts of different lengths to fit most telescope tubes. The longer (3/4") bolts work well with Sonotube optical tubes, while the shorter (3/8") bolts are best suited for thinner (metal) tubes. To drill the holes in the tube, use the drill template (illustration) of the base at the left. Lay the template on the telescope tube so that the long axis of the base is parallel to the long axis of the telescope tube. [. . . ] Slide the reflex sight onto the dovetail base and tighten the two screws. Replacing the Battery Should the battery ever die, replacement 3-volt lithium batteries are available in many retail outlets. Remove the old battery by sliding it forward from under the retaining clip. Slide a new battery under the retaining clip with the positive side (+) facing out. Using EZ Finder on Two or More Telescopes Extra dovetail mounting bases (#7099) are available for an economical price, allowing one EZ Finder sight to be used alternately on more than one telescope.
