the Custom Scientific 3nm FWHM filters were confirmed tonight to split the
very close emission lines of the [NII] doublet at 658.4 nm and the Halpha
line at 656.4 nm........

Richard,

Interesting image and I'm glad to hear that the filters 'work'.

......now if CS could just figure out how to lower the price........
