Takahashi FSQ106ED F5 Astrograph Telescope


Now introducing the NEW Takahashi FSQ-106! The last rendition, the FSQ106N, has long been held as one of the finest refractors on the market for film and CCD imaging. Wide field, large image circle, excellent color correction and a flat field were some of the features of the previous FSQ106N.

The new Takahashi FSQ telescope makes some significant improvements over its predecessor. The new FSQ telescope has significantly longer backfocus at 178mm to accommodate most CCD systems. Many CCD imagers have additional equipment in the light path such as filter wheels, adaptive optics, temperature control focusers and other accessories that take up precious focus travel. The new version has additional backfocus to accommodate most CCD equipment and even allows the use of binoviewers!

The Takahashi FSQ-106ED telescope also sports a new heavy-duty 4" focuser with a built in camera angle adjuster. This focuser will lift up to 5kg, or 11lbs, and includes the popular 10 to 1 microfocuser.

Takahashi has redesigned the optical system to a modified four element double ED Petzval system. This F5 optical system is optimized for imaging, yet it is also capable of outstanding visual images. Use the optional F3.6 (wow!) focal reducer for imaging applications and the optional Extender-Q for visual use at F8.

Another improvement on the new Takahashi FSQ106ED is the enhanced portability due to a new sliding dew shield. The Takahashi FSQ106ED is now airline portable at only 16.7" long when collapsed! The focuser and the aluminum castings will continue to be made one at a time for consistent, optimal quality.

NEW FSQ-106 EDX Series 

 

CCD and Digital Camera Options

 

FSQ-106 ED and FSQ-106-EDX calculations center on having the focuser draw tube out near the half-way position, as total travel is limited to 30 mm. 

 

The CCD or DSLR camera for Prime Focus needs to positioned at the “Back Focus” of  178 mm measured from the back edge of the green focuser of the Telescope.     #’s from FSQ-106 EDX Photo/Visual System Chart (TX).
