DESCRIPTION
The catadioptric telescopes of the Epsilon series are wide-field astrographs with an hyperbolic primary mirror. A corrector is integrated in the rack-and-pinion focuser and allows to obtain a flat field with stars less than 10μm at the edge of the 44mm image circle.
The Epsilon-130D has a focal ratio of F/3.3. Its very short focal length of 430mm offers a field of view of 5.9° and is therefore ideal for imaging large areas of stars and nebulae. Its secondary mirror is mounted on a reinforced spider to avoid any flexion. The rack-and-pinion focuser is equipped with a CAA (Camera Angle Adjuster) for photographic framing.
The collimation of the Epsilon 130D is particularly easy because it does not need to be done on a star. The optical axis is represented by markings on the 2 mirrors. Takahashi has designed a simple collimation eyepiece system particularly adapted to the Epsilon allowing the adjustment of the mirrors in daylight, a big advantage compared to a classical telescope.
Regardless of its photographic qualities, the Epsilon is a first-rate wide-field observation telescope. The observation of star clusters and galaxies will give you intense pleasure due to the fineness of the stars. It proves to be a fabulous instrument for the deep sky and the search for comets. The observation of the Lagoon and Trifid Nebula in the same field is extraordinary and striking.
