In case of using the photographic version of the CCS Herschel-Prism for visual application the user must make
absolutely sure that the neutral density filter OD 3.0 (#2458332) is mounted in the correct place directly above
the Herschel-Prism in the beam of light that is exiting from the Herschel-Prism into the eyepiece. This ensures
that no harmful amount of energy can enter into the eye of the observer. However it will be necessary to further
reduce Solar light for reaching comfortable brightness. This is being achieved either by adding a Solar Continu-
um filter, alternatively by using appropriate neutral density filters of the photographic version or by using a polar-
izing filter as explained on page 8/9.
The Baader Safety Herschel-Prism is an accessory which is to be used in combination with refracting tele-
scopes only. Any other optical designs (like Newton, SC, MAK and so on) use optical or mechanical parts near
the focal plane, which will be destroyed by the heat of solar radiation. If you want to utilize any reflective tele-
scope for solar observation, shield the front aperture with our patented Baader AstroSolar safety film. You will
find all information on AstroSolar safety film on our website
AstroSolar.com
.
Never use welding glasses, emulsion film or similar auxilliary aids for filtering Solar light. All these means are
not designed to fully shield off dangerous radiation of the IR or UV part of the spectrum.
