RE: [APML] Light pollution filters and Comet NEAT

["Jeff Ball" <jeffball@astro-photography.com>]

Steve,
Without looking at the specific spectral cutoffs of the LPR filter, my
guess is that you would significantly reduce the signal from the comet
as it probably has a pretty broad spectrum of light, similar to
galaxies.  I wish I had been out imaging, socked in with a nice low
pressure system that is stagnant.  Best wishes.

Best regards,

I posed this question over the weekend, but  everyone with clear skies 
was probably out imaging.
I'm interested in shooting Comet Neat from my SF Bay Area location, and 
wonder if a Hutech
IDAS filter will attenuate the comet in addition to the local light 
pollution.

Yes, I could try with and without, but the Bay Area has been plagued 
with marine fog for over a week.
I'll be lucky to get 10 minutes of holes in the clouds!

Thanks--Steve
