Takahashi Epsilon E-180 180mm ED Astrograph OTA

The Takahashi Epsilon E-180ED is a hyperbolic flat-field astrograph engineered for speed, precision, and unmatched imaging performance. Designed specifically for astrophotographers, this f/2.8 fast Newtonian astrograph delivers pinpoint stars across a 44mm image circle—perfect for full-frame DSLR and CCD sensors.

It features a revolutionary two-element ED corrector integrated into a rotating Crayford focuser assembly. This corrector ensures coma-free, flat-field performance without introducing chromatic aberration, even at the telescope’s ultra-fast focal ratio. With Takahashi’s signature build quality, the Epsilon-180ED delivers 10-micron stellar images, revealing fine detail in galactic structures, nebulosity, and comets.

The rugged optical tube assembly is fitted with precision collimation controls, a reinforced mechanical chassis, and pre-marked reference points for reliable setup and alignment. For serious imagers demanding speed and uncompromising optical clarity, the Epsilon-180ED stands in a class of its own.
