Main features

The optical tube assembly (hyperbolical Newton) gives an image very contrasted even with stars located at the edge of the field. Regardless of its photographic qualities, Epsilon-180ED is a first range telescope for large field observation. Observation of stellar fields, star clusters and galaxies will bring you so much pleasure, while the sharpness of star images will reveal the extraordinary possibilities of your astrograph. It proves to be a fabulous instrument for deep sky and comet surveys. The observation of Lagoon and Trifide nebulas in the same field is extraordinarily seizing.

The rack-and-pinion focuser has a rotary system for framing. A microfocuser (MEF-1) is available on option.
The Epsilon-180ED mechanical design quality, perfectly matched with its optics, will make delicate night handling such as collimation (to be trimmed in full day) and the installation of a photographic image or CCD a lot easier, like for instance : focusing, framing of the object, pointing of the guiding star, etc. Few other telescopes on the market make these operations as easy. The comfort of use of Epsilon-180ED allows you a fast control of your telescope adjustments and therefore gives you time to concentrate on the essential : to set your imaging process.

The primary mirror cell is equipped with 3 "double-action" collimation screws (pushing/drawing). Moreover, you have 3 screws with counter-nut to adjust the pressure under the primary mirror in order to minimize the stresses due to strong seasonal temperature changes.
The collimation of Epsilon-180ED is particularly facilitated for various reasons. It is not an high-resolution reflector thus the procedure is less rigorous than on a Cassegrain-like optical design ; collimation on a star will then not be necessary. The optical axis is represented by reference marks on the 2 mirrors. Takahashi conceived a simple system of collimation eyepiece particularly adapted to Epsilon-180ED. Consequently, you will be able to quietly collimate your Epsilon-180ED during daytime, which is a large advantage compared to a traditional reflector.
