FSQ-106
The ultimate astrograph FSQ-106 登峰造極之天體照相儀 The FSQ-106 is a state-of-the-art fluorite refractor that sets a new standard for innovation and color correction. It is excellent as a astrograph, not exhibiting inherent problems with field curvature and astigmatism. Takahashi's modified Petzval design employs two widely separated rear elements to correct field curvature and astigmatism to produce a flat field, high contrast image without any hint of lateral color. This design produces an amazing 88mm image circle that will fully illuminate a 35, 645, or 6x7 medium format camera and vacuum back roll film holders. The 4" apo
refractor, has a built-in camera angle adjuster that permits 360°
rotation of the camera, making the FSQ-106 the perfect astrograph. In
fact, this outstanding instrument can be used with a 4x5 vacuum back
camera! The exceptionally large image circle will permit the use of any
CCD camera. The double fluorite design which forms an image free of any
secondary color will produce exceptionally sharp, high contrast views of
deep sky objects or total eclipses. |

Sky-90 The latest telescope model from Takahashi is a truly portable design. The 90mm (3½") f/5.6 fluorite doublet apochromatic optical system is of outstanding quality, with a focal length of 504mm. The optical tube assembly is only 13.8" long, weighing 7 pounds; small enough for an airline 'carry-on'. Not only is this instrument an excellent choice for astronomy, it can be used as a portable high-quality telescope for birding. The oversize focuser has an adapter for 2" and 1¼" diagonals, and accepts the FS series photographic adapters.
