• 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.

• 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.

• The film is from the same material as our proven AstroSolar® Safety Filme 5.0 in A4-size, due to high demand now availble in a smaller size at an economical price, suitable as solar filter for small telescopes, finders, binoculars, spotting scopes and camera lenses

Versatile dovetail bar for telescope attachment to mounts with Losmandy level saddle plate

• Length: 180 mm
• Very solid in spite of its weight of only 434 grams
• Slotted holes, thread bores and countersunk bores allow a wide range of adaptations

New bag for Skywatcher mount EQ6-R and EQ6-R PRO
Transport and protect a mount is a prerogative of the Geoptik padded bags, practically two bags sewn into each other in the middle with a padding.
Geoptik now offers an alternative, a simple and robust housing which includes the use of the original polyuretane protection with function of protecting your mount.

Ecological and economic !!

Overall inner sizes are: 60x50x23cm - top: 4cm - bottom: 18cm

The K4R key ring lamp raises performance, technology and design to a new level. This small everyday helper housed in a high-quality and well-designed aluminium case reaches up to 60 lumens and provides wide area illumination. The first light in the new K-series, the K4R is rechargeable and is equipped with the additional safety of an SOS distress signal mode.

The Auriga image rectifier features a high quality Amici prism composed of BaK4 glass and with all surfaces treated with effective anti-reflective coatings, all to ensure maximum transmissibility and minimize the loss of brightness and contrast modulation.
