Takahashi Epsilon-160ED

The Epsilon-160ED is the newest addition to Takahashi's line of high-quality hyperbolic astrographs.

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 corrector lens to eliminate spherical aberration and coma. Compared to the conventional Schmidt camera design, the chromatic aberration is reduced by half, even out to large viewing angles.

The E-160ED reflecting telescope has an aperture of 160 mm and a focal length of 530 mm and provides a well corrected flat field for full frame imaging sensors.

Thorough aberration correction is realized by by optimizing the interaction of the hyperbolic mirror and the corrector. By using ED glass in the corrector, a spot image within 3 μm has been achieved at the periphery of a full frame imaging sensor. The E-160ED combines the ease of handling of the E-130D with the high performance of the E-180ED.
