The "Baby Q" Takahashi FSQ85ED telescope is the smallest member of the FSQ Series of flat field astrographs. Designed from the ground up for digital imaging. The Baby Q is the go anywhere, portable astrograph. Weighing less than 9 pounds and measuring 12.68” [322mm] when collapsed, this telescope will fit under an airline seat or fit easily into an overhead compartment for ultimate portability.
The Takahashi FSQ-85ED telescope comes equipped with a newly designed heavy-duty 78mm focuser with a built-in camera angle adjuster. Designed for all applications in mind, the focuser will lift your equipment, and keep it there without slipping. Inside the aluminum tube, you'll find Knife-edge Baffles that block off-axis light and provide maximum contrast. The scope has a significantly longer back focus at more than 200mm to accommodate most medium format CCD systems and even allows the use of binoviewers!
Takahashi redesigned the optical system in the Takahashi FSQ85ED F5.3 Astrograph Telescope to a modified four element double ED Petzval system. By adding a second doublet inside the tube the removing any astigmatism and acts as a field flattener. The Takahashi FSQ85ED F5.3 Astrograph Telescope optical system is incredible for imaging - providing wide, flat fields, high contrast, and no lateral color. Color correction from the near UV to the near IR ensures tight stellar images across the entire color range
The Takahashi FSQ-85EDX Flattener will expand the corrected image circle from a 28mm diameter to a 44mm diameter to fully cover any full frame sensor.
