SharpStar Optics Apochromatic Refractors

SharpStar Optics apochromatic refractors are built mainly for astrophotography, from compact triplets to multi-element astrographs. The 50EDPH and 94EDPH f/5.5 and the larger 140PH f/6.5 are triplets used with matched reducers. The 100QII f/5.8 quadruplet, the 121SDQ f/5.6 quintuplet and the Z4 100mm f/5.5 sextuplet build field correction into the design for a flat field on large sensors.

All also give sharp, color-free views at the eyepiece.
