The part that decides whether pointing is a pleasure · review
Astromania's 9x50 right-angle finder: fully multi-coated, with a crosshair reticle, objective focusing, two-screw-and-spring alignment and a Synta-style dovetail bracket.
The 90-degree viewing angle puts the eyepiece at the side of the tube, so a telescope pointed high does not force a crouch. The 50 mm objective at 9x shows faint stars that a red-dot finder cannot.
The bullets of this listing describe an upright corrected image, in the same words as Astromania’s correct-image 9x50. The title, though, says only “right angle”, while the other model’s title says “correct image”. Plain right-angle finders usually mirror the view. If a chart-matching image is the point, buy the one that names it in its title.
Two screws and a spring for alignment, a rotating objective ring for focus, a rubber damping ring, a machined aluminum body with dust caps, and a Synta-style dovetail bracket.
No true field, no illumination. Amazon’s item data gives 485 g (17 oz).
On November 7, 2026, Amazon.com listed it at about $69 from a third-party seller.

The bullets say upright and corrected, word for word like Astromania's correct-image model, but the title only says right angle. A plain right-angle finder usually mirrors the image. If a correct image matters, the [correct-image model](/reviews/finder-scopes-astromania-right/) states it in its title.
When the telescope points high, a straight-through finder puts the eyepiece where you must crouch under it. A 90-degree finder lets you look down into it.
Its Synta-style dovetail bracket slides into most finder shoes on Sky-Watcher, Vixen, Orion and similar telescopes.
