Version Visual Mark II.\u003c\/p\u003e\n\n\u003ch2\u003eSpace technology applied to safe solar observation\u003c\/h2\u003e\n\u003cp\u003eThe \u003cstrong\u003eBaader Herschel Prism Cool-Ceramic Safety Mark II\u003c\/strong\u003e is the absolute reference instrument for visual solar observation with refractors. The principle of the Herschel prism is straightforward: instead of filtering sunlight in front of the objective, it uses only \u003cstrong\u003e4.6% of the incident light\u003c\/strong\u003e reflected from the first surface of the prism for observation, diverting the remaining 95.4% — the high-intensity thermal energy — into the internal light trap system. The 4.6% transmission is further reduced by a factor of 1000 by the ND 3.0 filter included as standard, bringing the light reaching the eye to completely safe levels.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eCool-Ceramic\u003c\/strong\u003e technology represents the evolution of the light trap system: a multi-layer structure of thermal screens and heat-absorbing ceramic — the same technology as the thermal tiles of the Space Shuttle — absorbs radiant heat without overheating the surrounding environment. The prism remains thermally stable even after extended sessions. The fully enclosed housing eliminates any risk of glare or fire from emitted solar light: observation with this instrument is safe for private individuals, public institutions and schools \u003cstrong\u003ewithout the need for any additional front solar filter\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch2\u003eMark II: integrated rotation mechanism for polarizing filters\u003c\/h2\u003e\n\u003cp\u003eThe main innovation of the Mark II over previous versions is the \u003cstrong\u003eintegrated rotation mechanism for polarizing filters\u003c\/strong\u003e. Since the Herschel prism naturally emits single polarized light, combining this mechanism with the \u003cstrong\u003eBaader Single Polarizing Filter 2\" (#2408342, optional)\u003c\/strong\u003e and the included ND filter provides \u003cstrong\u003econtinuous stepless brightness adjustment\u003c\/strong\u003e — the optimal method for adapting solar contrast to the observer's preferences and seeing variations. All filters remain in the prism even during eyepiece changes: there is no need to refit them each time.\u003c\/p\u003e\n\u003cp\u003eThe Visual Mark II version includes the new \u003cstrong\u003eBaader Solar Continuum Filter 2\" 7.5nm (540nm) #2961581\u003c\/strong\u003e, which isolates the optimal spectral window for viewing solar details in green light, significantly improving the contrast of granulations, sunspots and faculae structure compared to pure white light observation.\u003c\/p\u003e\n\n\u003ch2\u003eCeramic Solar Finder, ClickLock and S58 dovetail\u003c\/h2\u003e\n\u003cp\u003eThe \u003cstrong\u003eceramic plate\u003c\/strong\u003e integrated into the prism body simultaneously acts as a heat trap and as a \u003cstrong\u003eSolar Finder\u003c\/strong\u003e: sunlight passing through the prism body forms a bright spot on the ceramic, allowing the telescope to be aimed at the Sun without looking through the eyepiece — simple and safe. The \u003cstrong\u003eClickLock® 2\"\u003c\/strong\u003e eyepiece holder locks any eyepiece with just 15° of rotation, without side screws that could cause mechanical stress — even with winter gloves. The \u003cstrong\u003eS58 dovetail\u003c\/strong\u003e attachment system with safety grooves on the 2\" bayonet and the new factory-preset 3-point adjustment system complete a mechanically professional build.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e⚠️ Warning:\u003c\/strong\u003e The Herschel prism can be used \u003cstrong\u003eexclusively with refracting telescopes\u003c\/strong\u003e. It is not compatible with reflecting telescopes (Newtonian, Cassegrain, Dobsonian) or systems with lenses in the focus zone.
