# 2961590
€ 285.00 Price excl. German VAT tax (19%): € 239.50- 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 (sold seperately: Baader Safety CoolCeramic Herschel Prism 2" Photographic (#2956510P , € 645,-) )
- 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).
