Main Features: Simple, affordable, and effective red dot sighting device for aiming your telescope Very easy to adjust; thumbwheels allow positioning of the red dot horizontally and vertically for precise telescope alignment An adjustable red LED dot is projected onto a non-magnifying viewing window to help aim the main telescope quickly and easily Includes mount bracket Material: Plastic Color: Black How to use a red dot finder: Remove the clear plastic sheet from the front and bottom to allow battery contact so the red dot appears when switched on Turn on the finder using the small rotary control on the side; look through the front hole to see the red dot and adjust brightness using the same control, which also serves as the on/off switch Set up your telescope as normal, but attach the red dot finder instead of the standard optical finder Point the telescope at a distant object such as a TV aerial or chimney; using a low-power eyepiece (25mm recommended), center and focus the object in the view Use the slow motion controls on the mount to position the object in the center of the eyepiece view Adjust the red dot finder using the two adjustment wheels so the red dot aligns precisely with the centered object; the front right wheel adjusts left/right, and the rear bottom wheel adjusts up/down Turn off the finder and wait until dark for night observation To use, turn on the finder and look through the viewing window, aligning the red dot with your target; once the red dot is over the star or planet, it should appear in the center of the eyepiece view Turn off the finder after locating your target to conserve battery Package Includes: Red Dot Finder Scope (includes button battery)
