  1. Takahashi America: The FS series of apochromatic refracting telescopes from Takahashi provides a balance of high performance, compact size, and low cost.  At its heart is a two-element fluorite lens set that provides outstanding performance for both visual and imaging applications.  The FS series makes use of several reducers, extenders and flatteners to further enhance its capabilities and performance.

    FS-60CB

    The FS-60CB is a 60 mm refractor that employs a multi-coated, two element fluorite objective lens with a prime focal length of 355 mm. 

    With the dedicated C0.72X reducer, the FS-60CB is converted to an f/4.2 instrument.  The combination results in a 40 mm diameter image circle with 60% illumination across the entire field.  Illumination is maintained at 95% or more out to a 25 mm diameter, and is 72% illuminated out to a diameter of 35 mm.

    With the dedicated FS-60 flattener, the resulting field flatness is greatly improved out to the four corners of a full frame DSLR sensor.  The resulting combination is an f/6.2, 374 mm instrument with an image circle diameter of 44 mm.

  3. Takahashi America: Like the FS series, the FC series are apochromatic refractors with two-element fluorite lenses.  The FC series have larger apertures and longer focal lengths than the FS series, and provide outstanding performance both for the visual observer and the digital imager.  The FC series has its own dedicated set of reducers and flatteners, and is also able to use some of these accessories from the TOA series.

     FC-100D

     The FC-100D series consists of an apochromatic fluorite Steinheil doublet with a 100 mm objective diameter.  Two focal lengths are available:  a 740 mm f/7.4 instrument, and a 900 mm f/9.0 instrument.  The front element uses an eco-glass for maximum light transmission, with a coated fluorite rear element for superb color correction. 

    FC-100DC

    The FC-100DC model features a fixed dew shield and a 2.2 inch rack and pinion focuser.  While a capable imaging instrument, it is designed with the visual observer in mind.

    FC-100DF

    The FC-100DF is optically identical to the DC model, but features an enhanced 2.7–inch focuser.  It also features a shorter tube length that provides additional back focus for digital imaging applications.  This added back focus allows use of the FC-35RD reducer, which converts the DF to an f/5.4 instrument.

    In this doublet design, Takahashi has paired the fluorite element with a low dispersion glass having a high refractive index.  This combination provides excellent optical performance across the entire visible spectrum with a Strehl ratio in excess of 97.6
    The FC-100DZ is a fluorite doublet with a 100 mm aperture and an 800 mm focal length.   In this doublet design, Takahashi has paired the fluorite element with a low dispersion glass having a high refractive index.  This combination provides excellent optical performance across the entire visible spectrum with a Strehl ratio in excess of 97.6% across this range.  In addition, to satisfy the increasing demands of today’s imaging system, this glass combination minimizes the blue halo sometimes present at shorter wavelengths.  This halo intensity is reduced by about 50% when compared to the existing FC-100D.
    The FC-100DZ is fully compatible with the accessories available used with the existing FC-100 telescopes, including the FC/FS Muli-flattener and the FC-35 0.66X Reducer.  With FC-35 reducer, this telescope becomes an excellent imaging system, illuminating a full frame chip at f/5.3.
    Mechanically, the FC-100DZ has a tube diameter of 95 mm and a retractable dew shield.  With the dew shield retracted and accessories removed, the total length is only 595 mm, easily carried on most commercial flights.  The FC-100DZ utilizes the same focuser used on the FC-100DF and DL and weighs approximately 3.8 kg.

  12. Takahashi America: 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 FSQ-130ED is the latest addition to Takahashi’s FSQ line.  The FSQ-130ED is a fusion of features from the TOA and FSQ series.  The front elements mimic the TOA series, with three elements of ED glass that almost eliminate axial chromatic aberration and spherical aberration.  The rear elements come from the FSQ-106 design, thus eliminating astigmatism and chromatic aberration.

     

    Through its design, the amount of light reduction across the image circle is minimal.  Out to about 44 mm, the light intensity remains 97%.  Out to 64 mm, light intensity is still a remarkable 92%.  Even out to 110-mm, the light intensity is above 78%.  This light intensity reduces vignetting and keeps stars across the field pin-point.  At prime focus the FSQ-130ED produces a 110-mm image circle with an extremely flat field. 

     

    The FSQ-130ED has a 130-mm aperture in an f/5, 650 mm telescope.  The FSQ-130ED features a retractable dew shield, a 360-degree camera angle adjuster, and a heavy duty, 4-inch rack and pinion focuser.  The focuser comes standard with a 7:1 fine focuser reduction.  The draw tube features two racks, allowing heavy imaging trains to be used without flexure of the focusing mechanism.  The FSQ-130ED can be coupled with several reducers and extenders, including the F/3 Reducer 0.6X and the 645 “super reducer”.

  13. 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

  14. Takahashi America: The Epsilon series of astrographs are specifically designed for exceptional astrophotography.  Takahashi’s proprietary optical design features a hyperbolic, concave primary mirror with a 2 element ED corrector lens to eliminate spherical aberration and coma.  Compared to the conventional Schmidt camera design, the chromatic aberration is reduced by half, even out to large viewing angles.

    The new ε-130D is the same aperture as the original but now uses a digital corrector. This corrector produces improved sharpness and a 1/3rd reduction in the size of the spot equaling the spot size of the E-180 at the edge producing a 44 mm diameter circle. The offset secondary insures better illumination of the image formed by the primary.

    The ε-130D has a 5.9° field of view which is perfect for imaging wide field objects like comets and objects with extended nebulosity. With a speed of f/3.3 and a focal length of 430mm the ε-130D will shorten exposure times, increase color saturation and will produce wide field high performance images.

  15. Takahashi America: The Epsilon series of astrographs are specifically designed for exceptional astrophotography.  Takahashi’s proprietary optical design features a hyperbolic, concave primary mirror with a 2 element ED corrector lens to eliminate spherical aberration and coma.  Compared to the conventional Schmidt camera design, the chromatic aberration is reduced by half, even out to large viewing angles.

    The ε-180 was introduced by Takahashi as the first of the new Epsilon flat–field hyperbolic astrographs since the 1980’s. The ε-180 was designed to be a very fast f/2.8 imaging system.

    This fast field photo visual astrograph is perfect for digital SLR's and CCD cameras.  The f/2.8 speed will enable the imager to record faint nebulosity not visible in slower instruments.  In addition, the appreciably shorter exposure times reduce tracking error and will produce pin point stars. The ε-180 will produce 10 micron stars across the entire 44 mm diagmer flat 5 degree field.

    The focuser has been improved to allow more precise focusing. Each has a metal insert with a special non-cold flow material to allow for correct focus.

  35. Takahashi America: Provides FSQ-106EDX4 like field flatness on the FSQ-85EDX
    When originally conceived, the FSQ-85EDX was meant for use with APS-C or smaller CCD or CMOS chips.  At image circle radii beyond about 14 mm, field curvature was evident in larger chips.  This new flattener will greatly reduce this field curvature, resulting in a practically flat field out to a 22 mm image circle radios.

  36. Takahashi America: The TOA series is a member of Takahashi’s line of triplet refractors.  In the TOA design, three lens elements are used, with the front and rear constructed from ED glass.  The resulting system achieves a high level of apochromatic performance for both visual observation and imaging.  Takahashi engineers have a undertaken a complete redesign of the triplet system, completely eliminating spherical aberration while minimizing axial chromatic aberration in the visible light spectrum.

    In typical apochromatic designs, the elimination of chromatic aberration is usually at the expense of increasing spherical aberration at various wavelengths.  However, with the TOA series, the focal shift across the entire visible spectrum from 436 nm up to 656 nm is less than +/- 0.01 mm.  This is less than 1/100 the aberration of a typical apochromatic design.

    TOA-150B

    The TOA-150B is a 150 mm apochromatic f/7.3 refractor with a focal length of 1100 mm.  It features a retractable lens hood, a 4 inch rack and pinion focuser with a 7:1 fine focuser, and a 360 degree camera angle adjuster.  A complete line of flatteners, reducers and extenders are available, including the 67-series flattener, which provides a 90 mm imaging circle. 

    A tube weight is standard to assist in balancing instrumentation or visual accessories.

    Optical tube only.  Mount and tripod sold separately.
