An amici prism allows for a comfortable 90° viewing position and creates an erect image without left-right reversal. This makes it especially suitable for nature observations but it can also be very helpful with astronomical observations. Particularly beginners may find it easier to orientate in the sky when they compare the view through the telescope with what they can see with their naked eyes.
With this amici prism an astronomical telescope can be used as a powerful spotting scope.
Suitable for refractor telescopes as well as Maksutov-Cassegrain style telescopes with 1,25" visual back.
