Tele Vue NP127is APO Refractor Telescope

Tele Vue NP127is

The NP127is maintains its 127mm f/5.2 optical specifications yet with a redesigned 4-element optical system. The larger rear lens group absolutely minimises vignetting in formats up to 50mm measured diagonally across the chip. An optional field corrector is available so the corners of the newly brightened edges are virtually as perfect as the centre of the field. To prevent restriction of the larger converging light cone the focuser has a 3" front aperture and a 2.4" rear aperture.
