True, but the penumbral region of a sunspot still looks better in white light - much better contrast with the surrounds. The white light filter I used was baader solar film; perhaps baader film gives better contrast than other white light filters? Perhaps a difference in aperture influenced my opinion? Alternatively my memory is failing (quite possible).
