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.
