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 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.
NOTE:
Price includes OTA only. Mount, tripod, tube holder and finder sold separately.
