  1. Takahashi America: The Takahashi FSQ-106EDX4 is a redesign of the popular FSQ-106 and is a superior flat-field super quadruplet refractor.  This redesigned version features a flat field advanced Petzval quadruplet design, with extra-low dispersion (ED) glass for super color correction in the UV, visible and IR wavelengths.  This optical design results in pin point star images and increased field illumination.  Designed from the ground up for digital imaging, this new 4 element / 4 group design is also capable of stunning visual performance.

    Some of the features of this outstanding design include:

    Completely new optics for digital imaging, featureing two premium ED elements for outstanding color correction
    An advanced Petzval design includes an almost full aperature G3 lens to ensure greater image illumination
    A flat field without the need for an additional flattener, across a large 88 mm image circle
    Generous 178 mm back focus allows the user to attach a variety of imaging cameras and accessories, 2 inch diagonals, and many other visual devices including bino viewers.
    A 4 inch, heavy duty focuser with a an included camera angle adjuster for precise rotation of CCD cameras
    An anti-torquing draw tube that uses a second rack located on the top of the tube and loaded with ball bearings to prevent any rotation when a heavy instrument package is attached.
    Airline portable, with a total length of less than 17 inches with the lens shade retracted
     Optical Tube Assembly only (mount, tripod, tube holder and finder sold separately).

  2. Takahashi America: This is the same telescope is the FSQ-85EDX, but includes the 1.01X flattener as part of the standard telescope assembly.  This is the same unit designated as FSQ-85EDP in Japan.
    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). 

    The FSQ-85ED is a perfect go anywhere imaging/visual astrograph.  Its outstanding features include:

    Premimum doublet extra-low dispersion (ED) quadruplet design
    44 mm diameter imaging circle, capable of accepting medium format CCD or DSLR cameras
    Large, heavy duty 72 mm diameter focuser capable of carrying medium format CCD or DSLR cameras
    Light weight, highly portable instrument perfect for use worldwide or in remote sites
    Built-in camera rotator allow the camera to be rotated 360° without loss of critical focus
    Uses a specifically designed Extender-ED 1.5x to increase focal length for high magnification viewing
