C-400 Classical Cassegrain |
 | | Takahashi C400 16 Inch Telescope |
The C-400 16" f/14 Classical Cassegrain is part of Takahashi's Observatory Series telescopes designed primarily for research and educational institutions. This telescope comes standard with a removable f/10.4 focal reducer where a wider field of view is required. Because the C-400 employs the Classical Cassegrainian configuration with a parabolic primary mirror and hyperbolic secondary, extremely high resolution can be obtained without sacrificing contrast or a flat field.
Secondary obstruction is only 29% with this instrument as compared to 40% or greater with typical Ritchey-Chretien Cassegrains. This instrument is designed for rigorous research applications and is constructed with meticulous craftsmanship throughout.
