Takahashi is now producing the long-awaited successor to its most popular astrograph. The FSQ-106ED ($3,995) has an aperture of 106 millimeters (4.1 inches) and uses a four-element Petzval design featuring special ED glass to guarantee pinpoint star images from the near ultraviolet to the near infrared. Its fully illuminated 88-mm image circle at f/5 and 178-mm back focus will accommodate a large selection of cameras and bino viewers. The tube length is an airline-compatible 16.7 inches when the dew shield is retracted. The FSQ-106ED also accepts a proprietary 0.75x focal reducer ($560) that offers a wider photographic field at f/3.64. Adapters for a variety of camera models are available.
