Astromania 9x50 Angled Finder Scope with Upright and Non-Reversed Image, Black 9x50 finder scope with 50mm objective lens diameter, brighter DSOs directly visible. Makes a large number of aditional stars available - a big plus for being able to successfully locate objects. Enjoy both a comfortable 90 viewing angle and an upright, non-reversed image. An integrated prism displays objects in a similar way to that with binoculars or spotting scopes. This finder scope makes using a star map much easier, and you can observe near the zenith at a completely relaxed angle. The achromatic optics provide a bright, true-to-life image at 9x magnification. In addition, the optical surfaces have been multi-coated to prevent irritating reflections. Folder fits onto most telescopes, easy focusing at the objective lens. Adjustment of finder scope alignment via two screws and spring.
