Description

This image was taken using a "semi-narrow" bandwith filter about 35 nm wide (642-677nm) obtained by cascading a Baader Fringe-Killer and an Astronomik ProPlanet IR 642 filter.

I think it proves that, when working with a limited range of light frequencies, the fast achromat can nevertheless produce decent lunar images.
