The Takahashi FSQ-106EDX4 is a redesign of the popular FSQ-106 and is a superior flat-field super quadruplet refractor. This redesigned version features a flat field advanced Petzval quadruplet lens system, with extra-low dispersion (ED) glass for super color correction in the UV, visible and IR wavelengths. This optical design results in pin point star images and increased field illumination. Designed from the ground up for digital imaging, this new 4 element / 4 group design is also capable of stunning visual performance.
Some of the features of this outstanding design include:
- Completely new optics for digital imaging, featueing two premium ED elements for outstanding color correction
- An advanced Petzval design includes an almost full aperture G3 lens to ensure greater image illumination
- A flat field without the need for an additional flattener, across a large 88 mm image circle
- Generous 178 mm back focus allows the user to attach a variety of imaging cameras and accessories, 2 inch diagonals, and many other visual devices including bino viewers
- A 4 inch, heavy duty focuser with a an included camera angle adjuster for precise rotation of CCD cameras
- An anti-torquing draw tube that uses a second rack located on the top of the tube and loaded with ball bearings to prevent any rotation when a heavy instrument package is attached
- Airline portable, with a total length of less than 17 inches with the 145mm diameter lens shade retracted
Optical Tube Assembly only (mount, tripod, tube holder and finder sold separately).
