Product Description

The Celestron 9x50 Right Angle Correct Image (RACI) Illuminated Finder is a great upgrade to the stock finderscopes found on many Schmidt-Cassegrain telescopes.

The 50 mm optics produce bright, sharp images with a magnification of 9X and a 5º apparent field of view. Meanwhile, the right-angle, correct-image design keeps objects right-side up and left-to-right correct, making it easier to locate objects as well as track them as they drift through the field of view. The eyepiece module can be rotated left or right so you can find the perfect viewing angle.

The double-crosshair reticle etched in the eyepiece makes it easy to center an object, whether you are aligning your computerized telescope or finding deep-sky objects on your own. The reticle can be focused separate from the finder itself. A battery-powered illuminator lights up the crosshair with a soft, red glow, and the illumination can be easily adjusted by turning the on/off knob.

The Celestron 9x50 RACI Finder comes with a sturdy bracket consisting of two rings and an integrated dovetail. Adjusting the alignment of the finder is easy with the oversized thumbscrews. The dovetail allows for easy attachment to and removal from most Schmidt-Cassegrain and EdgeHD optical tube assemblies without affecting the alignment of the finderscope.

Great solution for a sore neck!

I’ve been using this finder for over a year & it has saved my neck! It was an obvious choice for me as I had a Celestron mounting plate on my dobsonian telescope as well as my Celestron CPC 1100. It is a natural addition to a red dot/Telrad finder setup since it is erect image. Alignment is quick & easy when switching between the scopes. Stars are crisp and I can get down to m10 allowing for quick location of fainter objects. The crosshair illumination is too bright even at the lowest setting, so I leave it off 95% of the time. All that being said, I’d buy it again as there isn’t much else at this price point.

DWK RACI Finder Scope review

The finder scope was good but the lack of instructions was a real downer! Went to Google to find some direction much of which was garbage. Don't understand why an outfit like Celestron would release a product with NO instructions! VERY POOR!
