1. はじめに
The Orion EZ Finder II Telescope Reflex Sight is a non-magnifying sighting device designed to simplify the process of aiming your telescope. It projects a small, LED-powered red dot onto a wide viewing window, allowing you to quickly and accurately point your telescope at celestial objects. This manual will guide you through the installation, operation, and care of your EZ Finder II.

3. セットアップ
3.1. バッテリーの取り付け
The EZ Finder II uses one CR-2032 3-volt lithium battery. If not already installed, locate the battery compartment, typically on the side or bottom of the unit. Insert the battery with the positive (+) side facing up. Close the compartment securely.
3.2. Mounting the EZ Finder II
The EZ Finder II comes with a dovetail bracket designed to fit the quick-release dovetail mounting base found on many Orion telescopes. This bracket provides sufficient height for clearance from the optical tube.
- Locate the dovetail mounting base on your telescope.
- Slide the EZ Finder II's dovetail bracket into the mounting base.
- Secure the bracket by tightening the thumbscrew on the mounting base. Ensure it is firm but do not overtighten.
For telescopes without a compatible dovetail mounting base, a separate dovetail base can be purchased from Orion or compatible retailers and installed on your telescope's optical tube.
4. 操作
4.1. Powering On and Adjusting Brightness
The EZ Finder II features an adjustable brightness control. A small knob or switch, usually located on the side of the unit, controls both power and brightness.
- Rotate the knob clockwise to turn the unit on and increase the brightness of the red dot.
- Rotate the knob counter-clockwise to decrease brightness and turn the unit off.
Adjust the brightness to a comfortable level that allows the red dot to be clearly visible without overpowering the background sky or target object.
4.2. アライメント手順
Before first use, or if the EZ Finder II has been removed and re-attached, it must be aligned with your main telescope. This ensures that where the red dot points, your telescope is also pointing.
- During daylight hours, point your main telescope at a distant, stationary object (e.g., a distant tree, telephone pole). Center the object in the eyepiece of your main telescope.
- Turn on the EZ Finder II and adjust the red dot brightness.
- Look through the EZ Finder II's viewing window. You will see the red dot superimposed on the background.
- Use the two small thumbwheels on the EZ Finder II to adjust the position of the red dot. One thumbwheel adjusts horizontal position, and the other adjusts vertical position.
- Adjust the thumbwheels until the red dot is precisely centered on the same distant object that is centered in your main telescope's eyepiece.
- Once aligned, the EZ Finder II is ready for use.

4.3. Using the EZ Finder II for Aiming
With the EZ Finder II aligned, aiming your telescope becomes intuitive:
- Look through the EZ Finder II's viewingウィンドウ。
- Move your telescope until the red dot is positioned directly over the celestial object you wish to observe.
- Once the red dot is on your target, the object should be within the field of view メイン望遠鏡の接眼レンズの。
