Main Features: - Simple, affordable, and effective red dot finder for telescope aiming - Easy-to-use thumbwheels for precise horizontal and vertical adjustment - Adjustable red LED dot projected onto a non-magnifying viewing window for quick and accurate telescope alignment - Includes mounting bracket - Material: Plastic - Color: Black How to Use the Red Dot Finder: 1. Remove the clear plastic sheet covering the battery compartment at the front and bottom to establish battery contact. 2. Turn on the finder using the rotary control on the side. Look through the front aperture to see the red dot; adjust brightness or turn it off using the same control. 3. Mount the red dot finder onto your telescope in place of the standard optical finder. 4. Point the telescope at a distant, distinct object (e.g., a TV aerial or chimney). Using a low-power eyepiece (e.g., 25mm), center and focus the object in the eyepiece view. 5. Adjust the red dot finder’s alignment using the two external adjustment knobs: the front-right knob controls left/right position; the rear-bottom knob controls up/down position—align the red dot precisely over the centered object. 6. Turn off the finder and wait until dark. 7. To observe, turn on the finder, look through it, and align the red dot with your target. When the dot is centered on the star or planet, the object will appear centered in your eyepiece. 8. Turn off the finder after use to conserve battery life.
