RE: [ATM] Dark Sky Meter

["Richard Klappal" <klappal@xnet.com>]

I've got a photographic light meter (Quantum Instruments Calcu-light-XP)
that from several years ago (a bunch maybe) that reads down to 0.002 fc in
incident light mode.  I'll take it out and see what kind of readings I
get--incident and "reflected".

Being photographic, it is reading on an exponential scale rather than
linear.  All depends on what your use is--photographic/visual or fighting
light pollution.

Here are some resources to get you started.

You are welcome to start a Yahoo group if you want, but you don't have to.
You

not just telescopes.

Clear skies.
