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. As with the FCT-200 and FCT-250 Observatory fluorite refractors, this instrument is designed for rigorous research applications and is constructed with meticulous craftsmanship throughout. The optical tube assembly weighs 165lbs. so a heavy-duty, permanent equatorial mount with high-precision Go-To slewing such as Takahashi's Temma EM-2500 or EM-3500 (illustrated) is recommended for most applications.

Since this is a custom made telescope, each instrument is made to order and delivery times may vary. Please contact your authorized Takahashi dealer or Texas Nautical Repair Inc. for exact pricing and expected delivery times.
