Astromania 1.25" 90-Degree Erecting Prism Optical Prism Inside Rather Than a Mirror which Makes Your Image Clear and Sharp
Asin: B0140U9XXK | Model: SKU_AM_EP1D90 | PartNumber: SKU_AM_EP1D90 | Ean: 6970019291093
Features
- Typically, you see the picture standing upside down. But what if you also want to observe nature? With this 90-degree erecting prism transform your telescope into a telescope for nature observation with upright and left-right corrected image. This is a great diagonal for daytime terrestrial use and night time astronomy applications for telescopes or spotting scopes.
- Comfortable observation with 90-degree: Look pleasantly from above into your eyepiece, filter thread for any 1.25 filter and accepts standard 1.25 eyepieces.
- The prism gives you a bright and clear picture: The prism is made of genuine optically processed BK7 glass, high quality optical prism inside rather than a mirror which makes your image clear and sharp. The Amici prism looks as beautiful as binoculars, but you can zoom in much higher with your eyepieces.
- Simply insert the erecting prism into the 1.25 focuser and enjoy upright and right-angled images with your eyepieces - watch birds, deer at the edge of the forest, the summit cross on a mountain or a cruise ship far out on the sea.
- The prism housing is made of precision molded ABS plastic and the barrels are made of metal - which ensures a tight fit and long grip. Use a clamping screw made of aluminum to fix your eyepiece. So you can even look sideways through your telescope - the eyepiece will safely stay put and not fall out. From now on nature lies at your feet: even if it is far away.
