Product Description

Takahashi Epsilon 180 Telescope with EM-400 Mount and SR-L Mahogany Tripod

Hyperbolic Flat-Field Astrograph design offers up and amazingly fast effective focal ratio of f/2.8.  The Takahashi Epsilon 180ED catadioptric, extra low dispersion optics provide high quality images for BOTH visual observation AND large field imaging needs.  The wide, perfectly flat field supports traditional photographic formats as 24x36 (35mm), 6x6, 6x9 and works perfectly with mega pixel digital 35mm cameras and CCD imagers.
The Takahashi Epsilon 180ED features a newly designed corrector which provides amazing contrast and sharpness, combined with extreme accuracy.
Appreciably shorter exposure times reduce tracking error and produce 10 micron stellar images across the entire field.
The Takahashi Epsilon 180ED picks up faint details and nebulosity missed by slower instruments!
