APM 100 mm 90° Semi-Apo binocular

With a 100 mm binocular binoculars (Dual Reactor) we can observe extensive deep-sky objects and galaxies. With two eyes, faint celestial objects are much brighter than with the same aperture  conventional telescopes. Extensive nebulae are particularly spectacular with deep-sky filters csrewed into the eyepieces. The moon's hills can be observed with a spectacular 3D feeling.
