BRESSER Amici Prism 90° 31.7mm/1.25"
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.FEATUREScomfortable eye relief for refractor telescopes90°- viewing position and image without left-right reversalastronomical telescope turns to a powerful spotting scope1,25" visual backfully multicoated prismSCOPE OF DELIVERYAmici Prism 90° 31.7mm/1.25"

Vixen 1.25”/ 31.7 mm Star Diagonal
This Vixen 90° mirrored Star Diagonal, with 1.25” / 31.7 mm nosepiece connection, makes observing objects higher up in the sky much more pleasant and also allows the user to revolve an eyepiece to a more comfortable observing position. This star diagonal is a good quality option and compatible with a large array of refractors and Cassegrain design instruments. It will accept 1.25” / 31.7mm eyepieces and accessories and also has a threaded nosepiece, into which can be fitted 1.25” filters, or Barlow elements, saving you the bother of having to keep swapping these when using different eyepieces. The inside of the diagonal is blackened to minimise internal reflections and light scatter and the body has a pleasingly well-engineered feel to it, without being too weighty. Eyepieces and other accessories are held in place by a simple-to-operate knurled set screw. As this is a mirrored diagonal, it also corrects the up/down orientation of image in astronomical refractors and Cassegrain telescopes, but please note that left and right will still be inverted within the field of view. Not suitable for use with Newtonian telescopes.

Prismen & Zenitspiegel 

Der Zenitspiegel eines Linsenteleskops richtet die Bildorientierung zwar auf, belässt sie aber seitenverkehrt. Für terrestrische Anwendungen ist es wünschenswert, ein vollständig richtig orientiertes Bild zu bekommen. Dies wird mit dem Amici-Prisma erreicht, das einen bequemen 45° oder 90°-Einblick bietet und genau wie ein normales 1 1/4 Zenitprisma in den 1 1/4 Okularhalter des Teleskops gesteckt wird. Bei Refraktoren, Schmid-Cassergrain und Maksutovoptiken ist ein solches Bauteil unerlässlich.
