Baader Planetarium 2458105 90° Amici-prismadiagonaali T-2-kierteellä, 32 mm vapaa aukko

Terrestrial observation through a telescope often presents an upside-down or mirrored image, making it difficult to identify landmarks or follow moving subjects. The Baader Planetarium 2458105 90° Amici Prism Diagonal solves this by delivering a correctly oriented, non-mirrored view, so you see the world exactly as your eyes do. Whether you're birdwatching, surveying landscapes, or enjoying daytime nature viewing, this prism ensures a natural and comfortable experience.
