Solar Continuum Filter - 1.25" (BPSC125) and 2" (BPSC2)
Unsurpassed contrast of photospheric details is achieved by an extremely narrow half bandwidth of only 8nm. Functions like a monochrometer, suppressing the effects of atmospheric turbulence to provide images that appear markedly more stable.
Focus "Sweet Spot Generator" - completely eliminates the usual focusing guesswork - the image snaps to a razor sharp focus at the exact focal position. Image the sun the way professionals do!
IMPORTANT: The Solar Continuum Filter MUST be used in conjunction with a visual density white-light solar filter or Herschel Prism (with ND3.0 filter) in front of the lens. We suggest Astro-Solar ND 5.0 Visual Filter material, also from Baader Planetarium. DO NOT attempt to use this filter without a white-light filter in front of your main telescope optics. Serious damage to your eyes could result.
