It's not adviseable to use narrowband for visual use. Primarily because the narrow band of light waves they do allow to the eyepiece are to dim for the human eye. They're great for sensitive (very low lux) CCD long exposure use though.
But then again, if you eat lot's of carrots you may be able to use this type of filter for visual use.....
All astronomers should definitely boost their vitamin A intake to elevate their viewing experience!
