  B1800 Blocking Filter

  A Blocking Filter is a required component when using any Lunt solar filter or solar telescope products. The housing contains additional filters that are needed for safety when viewing the Sun. Do not use a Lunt Solar Systems telescope or filter without a Lunt brand blocking filter. Lunt Solar can only warranty safety or performance when one of their blocking filters is paired with a Lunt H-alpha filter or telescope.

  Focal Length Suggestions for Visual Use:

  • B600 : For visual use on telescopes with focal lengths up to 600 mm
  • B1200: For visual use on telescopes with focal lengths up to 1200
  • B1800: For visual use on telescopes with focal lengths up to 1800 mm
  • B3400: For visual use on telescopes with focal lengths up to 3400 mm

  When imaging with a Lunt Solar System it is recommended that the user opt for the next larger blocking filter than that recommended for visual use. This is due to the fact that most imaging systems require additional “back focus”. It’s important to realize that the blocking filter be moved further up the light cone. As a result, the aperture of the blocking filter needs to be larger to allow for the larger cone size.

  Focal Length Suggestions for Imaging Use:

  • B600: For imaging use on telescopes with focal lengths up to 400 mm
  • B1200: For imaging use on telescopes with focal lengths up to 600 mm
  • B1800: For imaging use on telescopes with focal lengths up to 1200 mm
  • B3400: For imaging use on telescopes with focal lengths up to 1800 mm
