Features 1、Auxiliary Tool: The finder scope is a refractor telescope designed for visual star finding, attached to the barrel of the main telescope, to search for objects to be observed. Its role is to guide the object to be observed to the center of the field of view of the main telescope to help the observer find the position of the object. 2、Optimal Viewing Comfort: With a 50mm objective lens offering 9x magnification, the finder scope provides brighter images for easy and comfortable star navigation. Straight angle viewing makes your search more relaxed, comfortable, and intuitively positions the objects to be observed. 3、Precise Targeting: Featuring a dual pane adhesive mirror, the finder scope is equipped with crosshair lines at the focal plane for precise targeting. It also comes with a dust cover to prevent fingerprints. 4、Advanced Multi Coating: The finder scope is made from premium optical glass with the lenses featuring an FMC coating. The optical surface undergoes multiple coatings to prevent irritating reflections. 5、Easy Installation: The finder scope is applicable to most telescopes and is easy to install. By adjusting the screws or springs on the finder scope mount on the objective, align the viewfinder to make targeting easier.
