Orion 9×50 Achromatic Crosshair Finder Scope

The Orion 9×50 Achromatic Crosshair Finder Scope features a multicoated 50mm achromatic lens assembly with 9x magnifying power which provides a bit more resolution over a 7x or 8x finder, while still providing a wide field of view to help locate objects. It’s an ideal step up from a red dot finder or smaller optical finder scope as the larger aperture will let you see fainter stars and even some deep-sky objects.

Orion 9x50 Achromatic Crosshair Finder ScopeThe field of view is 5.5 degrees and the finder scope has single crosshairs for easy, precise centering of objects. The view is inverted and reversed. The aluminum tube has a gloss silver finish on the outside and is painted flat black on the inside to prevent internal reflections. The rotatable front cell holds the objective lens assembly and acts as a dew shield. It is cut internally with baffle threads to prevent reflections and enhance contrast.

The Orion 9×50 Achromatic Crosshair Finder Scope comes with a cast-aluminum bracket with an innovative X-Y aim adjustment and a dovetail foot that fits the finder scope base on most Orion telescopes. Alignment of the finder scope with the main telescope is easy and intuitive by virtue of two perpendicular nylon thumbscrews and an opposing spring-loaded pin. The finder scope’s focus can be adjusted by loosening the knurled lock ring just behind the front cell, then rotating the cell either way as needed until focus is reached. The lock ring is then retightened against the cell.
