• 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

• 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.

• Safe solar observation! 100% UV-protection, 100% IR-protection, sun light intensity reduced by 99,999%
• Our Solar Viewer AstroSolar® Silver/Gold – MADE IN GERMANY – safely protect your eyes for visual solar observation. This is THE solution to see the partial phase of Solar Eclipses or even big sunspots with your own eyes!
• Consists of Baader AstroSolar® Silver/Gold Film, with eye-sided reflex-free viewing. Also blocks IR, thus no unpleasant feeling of warmth in the eyeball. Optical Density OD=5,0 
• CE / ISO certified: conforms to and meets the transmission requirements for eye safety: EN ISO 12312-2:2015 – Instructions in four languages (English, German, French, Spanish) on the inner side of the solar viewer

• 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.

The Sky-Watcher EQ8-R Pro is an exciting evolutionary progression of the popular EQ8 Pro. The EQ8-R Pro is an extra heavy-duty, observatory class German equatorial mount, with a payload capacity of up to 50kg. Quiet in operation, the EQ8-R is supplied with the Synscan Go-To handset and can automatically find and track over 42,900 celestial objects from its extensive computer database.
