The part that decides whether pointing is a pleasure · review
A 9x50 angled finder with achromatic multi-coated optics, a 90-degree viewing angle and two-screw-and-spring alignment.
The bottom line The comfortable finder for a telescope that looks up — and the listing does not say which way the image comes out.
Ninety degrees means looking down into the finder rather than along it, which is the only comfortable arrangement when the telescope is pointed near the zenith. Fifty millimetres of objective at nine times gives a 5.6 mm exit pupil and shows the brighter clusters and nebulae directly.
Two screws and a spring. It is the oldest arrangement there is and the easiest to work in the dark: the spring provides the third point, so two adjustments do everything. Six-screw finders are more rigid and much harder to align with cold fingers.
Image orientation. An angled finder may invert, mirror or correct the view depending on its prism. Knowing which — from one look at a recognisable shape — is what allows a star chart to be used with it.
“Fits most telescopes” is not a specification. Finder shoes differ between makers and sometimes within one maker’s range, so measuring the shoe on the telescope beats trusting the phrase.
German, French, Italian and Spanish Amazon stores ran from 95 € to 108 € on the day of the survey.
American and British Amazon stores list it in local currency, which the euro range above sets aside.

The listing does not say. Angled finders vary: some invert, some mirror, some correct. Establishing which one yours does — once, on a known shape — is what makes a chart usable at the telescope.
Nearly three times the light, which is arithmetic on the two areas. Brighter deep-sky objects become directly visible in the finder rather than merely inferred from the star pattern.
