Baader Planetarium 2" Safety Cool Herschel Prism Version P with Case -

The Baader 2" Cool Safety Herschel Prism delivers the finest white-light solar views obtainable and is the only white light filter to have been found to noticeably exceed the performance of Baader AstroSolar Film. The Herschel wedge prism provides safe full-aperture solar views with absolutely no image degradation. Views are noticeably superior in resolution and contrast to even the very finest and most expensive glass objective solar filters and films. The amount of Sunspot detail and surface granulation will surprise even the most experienced solar observer. Penumbra resolve into a staggering range of contrasts and fine wispy details. The solar disc is set against a jet-black sky, like observing the full moon at night! With this Herschel Wedge Prism, it becomes obvious that the lack of detail and contrast experienced with most other white-light filters was not so much due to the atmospheric seeing as you had thought. A further benefit is the true unfiltered nature of the spectrum passed by the filter. Unlike all objective solar filters, the Baader Herschel Wedge does not selectively filter any of the visual wavelengths. This provides a true white-light view and permits the use of additional eyepiece filters to selectively study any bands desired, without the compounding effects of a pre-filter.
The Baader 2" Cool Safety Herschel Prism is the finest solar wedge ever produced for amateur use. It is the culmination of Baader's many years of experience in the design and production of Herschel Wedges. Utilizing a precision 2" ultra-smooth wedge prism and optimized optical design for stray light elimination, the Baader Safety Herschel Wedge maximizes image contrast and sharpness. The large first-surface prism has high surface quality and smoothness over its entire surface, which will not break down at magnifications well over 100x, permitting full-disc photography and imaging with no resolution or contrast loss across the full field. Efficient internal baffling and prism rear-face multicoating further reduce scatter and maximize contrast.
The special precision, polished and coated Baader ND=3.0 filter is permanently pre-installed within the wedge housing (it MUST be present for any and all visual observation). This critical safety feature ensures that the ND filter will always be present, with no chance of accidentally viewing the unfiltered light as with some other Herschel wedges. The genuine Baader ND filters have been designed and produced specifically for Herschel usage and are the only ND filters ever to be produced with both surfaces fine optically polished and anti-reflection multicoated. These additional steps provide the highest image quality across the entire field, preventing any image breakdown and scattered light which are inherent in standard ND filters.
The modular design of the Baader Herschel Wedge incorporates a removable 2" nosepiece and Baader 2" Clicklock Eyepiece Clamp. The threaded machined aluminum body permits attachment of a full range of Baader accessories, as well as for close-coupling of cameras and Baader binoviewers.
