Product Questions

With the Herschel Prism photographic version, is the idea that you can replace the ND3.0 filter with one of the other ND filters and get a brighter image for doing photography? It sounds that way from how you describe it but I just wanted to make sure that the ND3.0 can be taken off and replaced with one of the other filters. Thank you.

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

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


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
