[AZ-Observing] Re: Galaxy Filter?

The description reads like the old Lumicon 'Deep-Sky' filter
from the late-70s/early-80s that just cut out the mercury and
night-sky lines, leaving the rest of the passband open. I would be
surprised if the effect was more than a very modest increase in contrast
on galaxies.
