Takahashi Epsilon-130 Astrograph

• Takahashi Epsilon-130 is a f/3.3 Hyperbolic Flat-Field Astrograph Telescope
• Takahashi Epsilon-130 has a super fast focal ratio of f/3.3
• Full 5 Year Manufacturer Warranty

Takahashi’s Epsilon series of astrographs are known for their exceptional design catered to astrophotography. The Takahashi Epsilon-130 OTA’s optical design features a hyperbolic, concave pirmary mirror. This mirror has a 2 element ED corrector lens to aid in eliminating spherical aberration and coma. The chromatic aberration is reduced by half, even with large viewing angles, when you compare the Epsilon 130’s optical design to that of a conventional Schmidt design.

The new ε-130 has the same aperture as the original but now includes a digital corrector. Using this corrector, the astrograph has improved sharpness and a 1/3 reduction in the size of the spot. This equalizes the spot size of the E-180 at the edge, producing a 44mm diameter circle.The offset secondary mirror provides better illumination of the image formed by the primary mirror.

The Epsilon-130 has a 5.9° field of view. This makes the astrograph perfect for imaging wide field objects like comets and objects with extended nebulosity. The focal ratio of f/3.3 and the focal length of 430mm allows the ε-130 to shorten exposure times, increase color saturation, and produce wide field images that are of the upmost performance.
