NJP Mount WHAT IS A TAKAHASHI EPSILON-200 ASTROGRAPH? S-ELL HD Tripod Epsilon-200 Astrograph PD5-XY Drive Controller (Non-Goto and without Autoguide Port) • Primarily designed for astrophotography, with a fast focal ratio, a flat photographic field and a large 56mm fully illuminated image circle. • Modified 8inch (200mm) hyperbolic primary mirror Newtonian design at f/4. • Hyperbolic mirror surfaces provide better spherical aberration correction over traditional parabolic or spherical primary mirror surface designs. • A dedicated field-flattener lens provides an extremely flat photographic field with a fully illuminated image circle large enough to cover most large format sensors – including Pentax 120 medium format roll-film. • Also offered packaged with the ultrasmooth (+/- 6 arc.sec P.E.) medium heavy duty (70 lbs load capacity) Takahashi NJP German Equatorial Mount. • First introduced in 1984 and stayed in production for about 10 years.
