Takahashi Epsilon-180ED

EPSILON-180ED F/2.8 is one of Takahashi’s new products in 2005. This new design incorporates an ED corrector to achieve an incredible photographic speed of f/2.8. This wide flat field instrument is ideal for photo and visual applications. It may be used with as an Astrograph for medium format, 35mm film and digital as well as many CCD cameras. Exposure Times will be greatly reduced at F2.8 and star images are a mere 10 microns across the filed. The Epsilon-180ED Hyperbolic Astrograph is unique and in a class of its own.
