The Epsilon series of astrographs are specifically designed for exceptional astrophotography. Takahashi's proprietary optical design features a hyperbolic, concave primary mirror with a 2 element ED corrector lens to eliminate spherical aberration and coma. The ε-180 was designed to be a very fast f/2.8 imaging system that is one capable of producing 10 micron stellar images across the entire super-flat field. The Epsilon-180ED suits both visual observation and large field imaging needs.
