  • 2" wedge prism according to Herschel - one-sided Phantom Group® anti-reflective coating, with ceramic solar finder and 2" ClickLock® eyepiece holder
  • Integrated rotation mechanism for polarising filters – the best method for brightness adjustment in visual solar observation and solar photography in white light
  • Stepless brightness adjustment is made possible in combination with the optional and the included Neutral Density Filter. The polarizing filters are not included in the scope of delivery
  • Including the for an uncompromisingly sharp solar image
  • S58 dovetail and Safety Kerfs on the 2" nose-piece, New 3-point adjustment system preset in the factory
  • Available in visual and photographic versions, please choose from dropdown
Baader Calcium GEN-II 1¼" with LPFC

Baader Calcium GEN-II 1¼" (#2961590 , € 285,-)

Baader Calzium GEN-II 1¼" with LPFC

  • Single filter (unstacked!), shows finest solar details in calcium K (Cak) lightFor solar photography only in combination with enclosed AstroSolar photo film ND3.8 or an Herschel prism
  • Enhanced contrast matched to quantum efficiency and s/n ratio of typical CMOS cameras.
  • Reflex-Blocker™ coatings, for maximum immunity to retro-reflection from nearest auxiliary optics, even under the most adverse conditions
  • Identical filter thickness to existing standards, with utmost care for homofocality
  • Reflex-Blocker™ hard coated and planeoptically polished – with sealed coating edges (Life-Coat™)
  • Blackened edges all around, with filter-lead-side-indicator in the form of a telescope-sided black outer rim
  • Supplied with AstroSolar photo film ND 3.8, size: 200 x 290 mm - for pre-filtering sunlight
  • The calcium filter Gen-II must NOT be used in the light path WITHOUT pre-filtering.
  • Visual observation is not possible with the calcium filter, as the eye is practically blind in this part of the spectrum. Never point the telescope directly at the sun with only the calcium filter (without an additional attenuation filter).

UHC-L / Ultra-L-Booster-Filter

UHC-L / Ultra-L-Booster-Filter (various versions available)

UHC-L / Ultra-L-Booster-Filter

  • Visual and photographic UHC-L Nebula filter with highest transmission
  • Ultra High Contrast L Filter blocks city lights and increases contrast of nebula and comets (C2 lines)
  • Can be used as LED-opimized Luminance filter for RGB-Imaging wtih skyglow suppression
  • Blue transmission optimized to block blueish skyglow caused by LED car- and streetlights.
  • Creates a much brighter image than a conventional Nebula filter
  • Ideal for deep-sky observers. This UHC-L filter is the perfect visual complement to narrowband OIII filters.
  • Reflex-Blocker™ hard coated and planeoptically polished – with sealed coating edges (Life-Coat™)
  • Blackened edges all around, with filter-lead-side-indicator in the form of a telescope-sided black outer rim

 

H-alpha Bandpass-Filter (20nm)

H-alpha Bandpass Filter (20 nm) (various versions available)

H-alpha Bandpass-Filter (20nm)

  • H-alpha filter with 20 nm FWHM (CWL 656.3 nm), thus excellently suited for visual use at night - and photographically with CCD and CMOS cameras at telescopes with all f-ratios. Warning: this filter alone is not suitable for direct viewing of the sun!
  • With new, highly effective UV/IR block coating from 300 nm to 1400 nm
  • Similar to the Super G filter in O III, the 20 nm H-alpha filter is an outstanding high-contrast deep-sky H-alpha/red filter for RGB applications, optimised for all colour CCD and CMOS chips. It enables high-contrast images of H-II regions (e.g. North America nebulae) even from light-polluted environments.
  • Front-Reflex-Blocker™ hard coated and planeoptically polished – with sealed coating edges (Life-Coat™)

 

O-III Super-G Filter (9nm)

O-III Super-G Filter (9nm) - CMOS optimized (various versions available)

O-III Super-G Filter (9nm) - CMOS optimized

  • 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.
