The Baader Solar Continuum is a true narrowband filter featuring 10nm half-bandwidth (HBW) at the passband of 540nm while at the same time supplying maximum spectral transmission.
It greatly enhances the view of solar granulation and fine sunspot detail by transmitting a very specific bandwidth. It improves contrast notably and more importantly reduce the effects of atmospheric turbulence.
NOTE OF CAUTION
You must ONLY use the Solar Continuum Filter in conjunction with a safety aperture filter for your telescope or Baader Herschel wedge. Otherwise serious eye damage or blindness may result.
Filter cell height: 7mm
