CaK filter

Yes does sound similar to the baader k-line filter. Even though it' says CaK it's to broad a wavelength at 7nm so will only show more contrast in the white light spectrum. Nothing wrong with that, I use the baader k-line filter for white light imaging. 

Recently imaged yesterday using it with a Hershel wedge and an 80ed refractor.

Looks interesting... so not strictly as good as dedicated CaK, but still good...
