This is the newest and 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. Easily airline transportable at 12.68" [322mm] collapsed. The "Q". It weighs less than 9 pounds, so a smaller high quality mounting will support it.

The optics are the same premium double ED Takahashi 4 element optical system as the FSQ-106ED and they produce the same flat-field color-free images. The image circle will allow medium format CCD or DSLR cameras to be used with the Baby "Q" to produce very high quality images of deep sky objects with a large field flat field.

The FSQ-85ED also features a newly designed focuser with built-in fine focuser, made for imaging with medium format CCD cameras. This 72mm focuser had been designed to handle CCD and digital SLR cameras with great rigidity.

Not only is the Baby "Q" a first rate astrograph, it has also been designed to be an excellent visual instrument. With over 200mm of back focus, it can accommodate any combination of diagonals or bino viewer. Color correction from the near UV to the near IR insures tight stellar images across the entire color range.

The FSQ-85ED is the perfect "go anywhere" imaging/visual astrograph!
