SharpStar EDPH Triplet APO Refractors

SharpStar EDPH refractors are compact triplet apochromats aimed at astrophotography, each paired with its own focal reducer or flattener. The 50EDPH f/5.5 is a tiny wide-field scope that travels anywhere, and the 94EDPH f/5.5 has a 517mm focal length for nebulae and larger galaxies.

The collection also holds the dedicated 0.8x reducers for the 61, 76 and 94EDPH, the 0.84x reducer for the 50EDPH and the 61EDPHIII flattener, so you can complete or upgrade an EDPH setup.
