Hyperion Zoom Mark IV is the fourth generation of Baader Zoom eyepieces, offering great image quality, 68° wide field of view and the improved Clickstop Action that clearly defines the position of 5 focal lengths (8, 12, 16, 20 and 24mm), a must for effortless binoviewing.

• Containing: T-2/32 Diagonal with focusing 1¼" eyepiece clamp (#2458125) and 1¼" nose piece (#2458105)
• Connection objective side: T-2 internal thread 1¼ "barrel
• Connection eyepiece: T-2 external thread and focusable 1¼ "eyepiece
• Excellent for Baader Maxbright binoviewer

• 2" ClickLock Diagonal Mirror
• Oversized 2 "dielectric lamda / 10 levels with 112mm optical length
• Mirror repels UV and IR radiation, provides high security at the solar observation in white light and with Ha-sun filters
• Scratch-resistant, hard-coated mirror surface for safe cleaning, scratch-resistant even in extreme conditions
• Baader 2" ClickLock clamp for ultrafast clamping action
• Removable 2" Safety Kerf nosepiece

• Much larger prism as in the so-called "Erecting prism"
• Many Erect image prisms have only 19 mm free passage opening and therefore are not suitable for terrestrial observations at low magnifications, because the field of the eyepiece is shaded by the too small prism.

• 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.
