Baader Planetarium

• Available again for a limited time: Carl Zeiss 1¼" Abbe Barlow lens with T-2 thread made in Germany by Carl Zeiss in Jena – with 1¼" / T-2 ClickLock eyepiece clamp by Baader Planetarium
• visual Barlow lens and photographic eyepiece projection in one system
• Direct T-2 Adaption possible - extends magnification up to 3x - without loss of quality
• The image quality is only exceeded by our 3x-8x flat field FFC-Converter, in case the projection factor exceeds 3x

• Improved version of former MX-Mount

• 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.

• O-III Super-G filter with 9 nm FWHM and a maximum transmission of 97%.
• For visual and photographic observation of planetary nebulae and supernova remnants, even with small telescopes
• Can be used as a "Super-G filter"  replacement for RGB photography. While regular G-filters suffer from bad seeing due to air turbulences, the narrow range of 9 nm passes less thermal noise, i.e. sharper images. Nevertheless, the transmission window is large enough not to be considered a pure narrowband filter.
• CMOS-optimized coating technolog with much steeper slopes of the filter passband - for increased contrast, longer life and to avoid reflections.

• To connect Hyperion eyepiece to larger telescope systems
• Requires Hyperion DT-ring SP 54i / M62a

• Baader H-alpha Narrowband Filter – Precision Grade
• 6.5 nm FWHM, recommended for optical systems from > f/3.4
• Reflex-Blocker™ hard coated and planeoptically polished – with sealed coating edges (Life-Coat™)

• Optimized for modern CMOS cameras, but likewise excellent for CCD camera technologies

We explicitly warn against observing the sun with a DeepSky 6.5 nm (equivalent to 65 Ångstroem) H-alpha narrowband filter, specialized solar chromosphere and prominence filters from SolarSpectrum start at 0.8 Ångstroem. Photographic experiments with a camera are theoretically possible, but by no means observe the sun with naked eyes – you endanger your eyesight!

• For afocal projection photography
• ClickStop Twist-Lock-Mechanism

Photography with larger cameras
