    • Visual and photographic UHC-S Nebula filter
    • Ultra High Contrast L Filter blocks city lights and increases contrast of Nebula
    • Planeoptically polished for the highest image quality. 
    • Creates a much brighter image than a conventional Nebula filter.

    • The best visual and photographic filter for contrast enhancement for all telescopes, without loss of image brightness!
    • The effect of the element neodymium as filter material is very impressive. When added to optical glass, it enhances contrast, enhances the red colour in the image (especially with Mars and Jupiter) and it darkens the spectral region which is particularly marked by street lamp light, which is the biggest contributor to the nightly "Skyglow".
    • Planoptically polished and MC-coated – with IR-cut coatings!, without any loss of sharpness as a single filter in front of a binocular or be used for afocal projection with digital cameras (far from the focal point!)
    • The IR spectral range is blocked making stars much sharper when used with dSLRs.

    • 1¼" Contrast Booster Filter that completely eliminates false color
    • Removes the bluish "hue" (=lack of contrast) during lunar, planetary, solar and terrestrial observation
    • Boosts contrast and sharpness for fast achromatic telescopes - with over 95% transmission
    • Planeoptically polished, non-ageing sealed coating edges

    • NO halos, NO reflections, NO ghosting
    • non-ageing sealed coating edges

    • Blocks UV below 400nm and IR above 680nm
    • Maximum transmission, scratchproof hard coated
    • non-ageing sealed coating edges

    • Blocks UV below 400nm and IR above 680nm
    • Maximum transmission, scratchproof hard coated
    • non-ageing sealed coating edges

    • AstroSolar® Safety Film 5.0 for solar observation and photography at high magnification, telescope quality, Optical Density (OD) = 5.0
    • Safe for visual solar observation (with additional optics) and imaging
    • This highest precision film consistently produces strehl ratios of 94 to 96 percent at interferometric tests – thus it performs optically like a Fluorite Triplet Lens by Carl Zeiss or Astro Physics
    • AstroSolar Safety Film is best suited for precision work with all astronomical telescopes and binoculars – just as well as for all photographic camera- and tele-lenses
    • For more than 25 years on the market, the only film-material made to not deteriorate the optical wavefront, it does allow to attain high magnification with any long-range optics without reducing sharpness or contrast of the solar surface.

    • Baader-FlipMirror II Star Diagonal (BFM II) with three ports:
      • Straight-through (S52, M48 and T-2 on both sides) for full-frame camera, spectrograph, or other instruments
      • Adjustable T-2 thread on top for eyepiece clamps, video modules (up to 32 mm image circle) or even a binoviewer
      • Bottom flange for the optional Off Axis Guider for Baader FlipMirror II (BFM-OAG)(#2956951, € 98,-) or for an optional calibration lamp for quick calibration of spectra without removing the spectrograph

    • Flat field free of optical aberrations like field curvature, coma, astigmatism and chromatic aberration across an entire APS-C sensor.
    • Unlike the larger RASAs that work with DSLR and large CCD cameras, the 8” model was designed with color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras in mind. The telescope does not work with standard DSLR cameras.
    • NEW Ultra-Stable Focus System – six precision sealed ball bearings virtually eliminate image shift.
    • Integrated air cooling system –12V DC MagLev fan reduces cooldown time and provides optimal air flow while filtering out dust.
    • Internal filter mount – seamlessly accommodates a Light Pollution Imaging Filter into the optical path.
    • CGE dovetail mounting rail.
    • Performs over a wider spectral range than most telescopes, from 390-800 nm, so more of the light passing through the astrograph is in sharp focus.

      • This Celestron T-Ring attaches to Canon EOS DSLR and SLR camera bodies
      • Sturdy bayonet flange locks in place just like a lens, providing secure contact
      • Attaches to a variety of camera adapters and accessories via standard T-Threads

    This T-Ring fits EOS model cameras only.  It will not work with other Canon camera bodies.
