TAKAHASHI FSQ-85ED BABY Q REFRACTOR TELESCOPE
The FSQ series of telescopes were designed with the astro-imager in mind. Featuring a four-element lens system made with superb ED glass, the FSQ produces a virtually flat field across a large image circle. In models other than the FSQ series, the image circle is defined as the circle in which light intensity is 60% or greater. However, because of the outstanding performance of the FSQ series, for these models the image circle is defined as the area where star images are 30 microns or less. In all FSQ telescopes, the light intensity across the image circle is greater than 70%.
The Takahashi FSQ85-ED is the most portable member of the FSQ Series of flat field astrogrpahs. This refractor telescope was designed from the ground up for digital imaging, and is the go anywhere portable astrograph. Easily airline transportable at 12.68" collapsed, the "Q" will fit under under an airline seat or in an overhead compartment. It weighs less than 9 lbs, so a smaller high quaily mount will support it.
The FSQ-85ED also features a newly designed focuser with a built-in fine focuser, made for imaging with medium format CCD cameras. This 72 mm focuser has been designed to handle CCD and digital SLR cemeras with great rigidity.
In addition to being a first rate astrograph, it has been designed to be an excellent visual instrument as well. With over 200 mm of back focus, it can acommodate any combination of diagonals or a bino viewer. Color correction from the near UV to the near IR insures tight stellar images across the entire color range.
Optical Tube Assembly only (mount, tripod, tube holder and finder sold separately).
