Baader1¼" Amici-erecting-prism 45° with 24mm free aperture
|Delivery time:||More on the Way to us|
- Much larger prism than other so-called "Erecting prisms"
- Many Erect image prisms have only 19 mm free passage opening and therefore are not suitable for terrestrial observations at low magnifications, because the field of the eyepiece is shaded by the too small prism.
- Correct image orientation
- Excellent for terrestrial viewing (for high-power astronomical viewing, choose one of our deluxe Amici star diagonals).
