Baader Solar Continuum Filter 1.25" Stacked W/3.8 Photo Film - FSOL-1D

Baader Solar Continuum Filter 1.25" Stacked W/3.8 Photo Film

• 1¼" Double Stacked Baader Solar Continuum Filter. 8nm / CWL 540nm.
• Includes AstroSolar Photo Film ND 3.8 200x290mm. Includes two Baader Solar Continuum Filters which have been stacked for even higher contrast.
• Enhances the contrast and reduces the effect of atmospheric turbulence.
• This filter must be used in conjunction with a Baader Herschel Wedge or Baader AstroSolar Safety Film for solar observations otherwise equipment damage may occur. Baader AstroSolar Safety Film ND 5.0 must be used for visual observations.

Ensures highest contrast in the photosphere of the sun. The filter works as a monochrometer - suppressing the effects of the atmospheric turbulence and results in images that are significantly sharper. Owners of SCTs and refractors will benefit as red and blue wavelengths are completely excluded, with the transmission area peaking at 535nm where telescope optics are sharpest and free from chromatic aberrations.

The combination of AstroSolar Photo Film (ND 3.8) and Solar Continuum filter is used exclusively for photography of the sun at high magnifications. This combination is highly apt to capture the finest solar surface detail and granulation at extremely high magnification while enabling ultra-short exposure (measured in milliseconds) in order to freeze atmospheric turbulence.

Warning: The supplied AstroSolar Photo Film ND 3.8 is for photographic applications ONLY and MUST NOT be used for visual observations.
