90° Amici prism with 2″ eyepiece mount and 2″ barrel
Including reducing sleeve 2″ to 1¼”
Excellent for terrestrial observation with 2″
eyepieces.
Not suitable for high magnifications – for high quality ones
it is better to use high-magnification astronomical images
our mirrors and normal prisms, since the roof edge has the so-called “split”
effect and the long light path produces a chromatic aberration.
