Sky-Watcher Skyhawk-1145P 114mm (4.5″) f/500 Parabolic Newtonian Reflector Telescope. The SKYHAWK-1145P models feature premium-quality Parabolic Primary Mirrors, normally found in larger more expensive telescopes, to eliminate spherical aberrations, producing even sharper, higher-contrast images which are full of detail. A parabolic or more accurately a “paraboloidal” mirror, is ground to a shape which brings all incoming light rays to a perfect focus, on axis. In addition they feature 0.5mm Ultra-Thin secondary mirror supports, to reduce diffraction spikes and light loss.
