2" barrel for professional Solar-Photography and White Light Solar Observation. For photo-visual use the addition of a polarising filter set will allows you to reduce glare and maximise contrast.
Suitable for use with refractors with 2" focuser assemblies.
Not suitable for reflecting telescopes or catadioptic scopes (SCT, ACF or Maksutov).
The Lunt White Light Solar Wedge is based on a Herschel wedge where a prism directs unwanted radiation away from the light path to the back of the wedge. The internal ND3 filter results in an image that has to be seen to be believed. Pure and natural in colour with a wealth of subtle detail.
