Takahashi Epsilon E-130D Reflector OTA

$2,600.00

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.  Compared to the conventional Schmidt camera design, the chromatic aberration is reduced by half, even out to large viewing angles.

The new ε-130D is the same aperture as the original but now uses a digital corrector. This corrector produces improved sharpness and a 1/3rd reduction in the size of the spot equaling the spot size of the E-180 at the edge producing a 44 mm diameter circle. The offset secondary insures better illumination of the image formed by the primary.

The ε-130D has a 5.9° field of view which is perfect for imaging wide field objects like comets and objects with extended nebulosity. With a speed of f/3.3 and a focal length of 430mm the ε-130D will shorten exposure times, increase color saturation and will produce wide field high performance images.

Takahashi’s Epsilon series of astrographs are known for their exceptional design catered to astrophotography. The Takahashi Epsilon-130D 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-D’s optical design to that of a conventional Schmidt design.

The new ε-130D 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-130D 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-130D to shorten exposure times, increase color saturation, and produce wide field images that are of the upmost performance.
