Baader 2" Cool-Ceramic Safety Herschel prism, Visual and photographic

There is no better way for uncompromising Solar Observation / Solar Photography in white light

Attention

Every Solar Diagonal needs additional neutral density filters since the reflected energy of the first surface prism (4.6%) still is a factor of 1000 too large for the human eye. All Baader Solar Diagonals are delivered with a pre-mounted ND 3.0 Baader precision 2” light reduction filter. The photographic version includes other ND-Filters to achieve shorter exposure times. Use with care!

  • Space-Technology: The exiting beam in the Baader Safety Herschel Wedge is fed into a heat cage separated from the prism body. Like on a Space Shuttle a ceramic tile forming the back end of the heat cage absorbs the radiant heat without overheating its surroundings. The closed prism body offers perfect safety for educational work.
  • Solar Finder: The translucent ceramic tile acts as projection screen for the unfocused image of the Sun. Aiming the telescope at the Sun becomes very easy.
  • ClickLock 2“ Clamp: Securely clamp any eyepiece with only the push of a lever. Change eyepieces single handedly – even in winter with heavy gloves.
  • Filter Holder: A 2“/M48 threaded ring couples the 2“ ClickLock-Clamp to the body of the Safety Herschel Wedge and acts as a filter holder for 2“ filters.
  • Solar Continuum Filter (10nm HBW/540nm CWL): Included as standard filter
  • Optional recommended accessories:2“ Baader Polarizer-Filter (# 2408342) mounts into any 2“ eyepiece or 2“ to 1.25“ reducer for adjusting image brightness simply by rotating the eyepiece. Reducer ring 2“to T-2 (#1508035) allows to mount any DSLR-camera T-mount directly on top of the Solar Diagonal body

Excellent for hard core solar observers & Photo
I use the photographic model for both visual and photography. I use it with a TV 85 APO refractor and a 152mm Officina Stellare APO triplet refractor.. I was concerned that my TV 85 APO wouldn't have enough in focus for photography. But with the removal of the Click lock and replacement with the Tmount adaptor and my Niikon DSLR it comes to focus with about 3/16" to spare on focuser travel. The other scope is no problem either.
Optically this is the ultimate for white light photography. I also have BAADER Astro Solar Film filters that up to now have been my choice. But the Hershel Wedge gives even better results with fine detail and nice crisp images without flare or ghost images. The Solar Conitinuum filter is designed to work with achromats but even APOs will benefit. Larger magnification images hold together extremely well..
The real question is whether the big difference in cost between the Hershel Wedge and BAADER Astro Solar Film is giving the best bang for the buck? If you are only an occasional observer, not a photographer, it may not be worth it. But if you are a hard core solar fan than I recommend it highly. By the way also have a Ha solar scope and while that is fantastic....the two views are very different. If you don't know what I am talking about....read up on the differences and than you can decide if you want to get the wedge.
  • Construction and quality are laboratory grade, fantastic images visual and photo
  • Expensive but worth it if you are a solar fan
