Takahashi Epsilon 180mm Astrograph
The Takahashi E‑180 Epsilon ED Astrograph OTA is a fast, flat-field imaging powerhouse built for serious astrophotography. Takahashi’s signature combination of a hyperbolic primary mirror with a two-element ED corrector sharply reduces spherical aberration, coma, and chromatic flaws—giving you clean, pinpoint stars across a full-frame sensor. With a 180 mm aperture and a short 500 mm focal length at f/2.8, this astrograph delivers ultra-wide views and extremely short exposure times—perfect for capturing faint nebulae, expansive star fields, and deep-sky treasures with rich color and detail. The optical design produces sharp star images across a generous 44 mm image circle, making it ideal for modern full-frame cameras.
Built with an improved rack-and-pinion focuser for precise focus control, the E-180ED balances high performance with field usability. Whether you’re imaging comets, galaxies, or majestic nebulae, this astrograph combines Takahashi’s optical heritage with modern ED correction for exceptional wide-field results. Note: Price includes OTA only. Mount, tripod, tube holder, and finder sold separately.
Reveal More, Faster!
With its exceptionally fast f/2.8 optical system, the E-180 is designed to pull in faint details that slower telescopes simply can’t reach. Shorter exposures not only reveal subtle nebulosity more easily, they also reduce tracking demands, giving you sharper, more consistent results night after night.
Hyperbolic Optics
Takahashi’s proprietary hyperbolic primary mirror paired with a 2-element ED corrector delivers a beautifully flat, coma-free field. Stars remain tight and perfectly formed from corner to corner, even on large sensors, making this astrograph ideal for wide-field targets and high-resolution imaging.
Enhanced Stability
The improved focusing system features a durable metal insert and a non-cold flow material that maintains accurate back focus, even under temperature swings or when supporting heavier imaging trains. This added stability ensures precise focusing performance and dependable results throughout long imaging sessions.
