Takahashi Epsilon-180ED Hyperbolic Astrograph
This fast field photo/visual astrograph is perfect for digital 35mm cameras and CCD cameras. The great speed will enable the imager to record faint nebulosities invisible in slower instruments. Perfect for viewing comets and galaxies.
The Epsilon Series are corrected Hyperbolic Photo/Visual Astrographs providing wide field astrographs and wide field viewing of the object.
The Epsilon 180 is a highly portable, and versatile hyperbolic photo/visual astrograph. Most asrographs provide wide field photographs, but in addition to this the E-180 can deliver wide field views of the objects to be photographed as well. The photographic and visual fields are flat at the f/2.8 speed. This makes the E-180 perfect for photographing comets and groups of galaxies. Finding these objects is made easier with the optional 7x50 finder.
The Epsilon 180 is a doublet using ED glass, perfecting chromatic aberration to less than that of the Schmidt camera.
