    Folks,

      I just got back some Iridium flare photos that I shot a couple of
weeks ago and they are perfect (composition, framing, timing etc) except
for one "little" thingie .... sky fog is really obvious in the 40-sec
exposures (using Fuji ASA 800 film).

      I have Orion's 1.25" SkyGlow Broadband filter which I use for DSO
work and would like to use it when  taking my piggy-back satellite
photos. I was wondering if this is possible and how one would attach the
filter to the lens being used. For the iridium flares, it seems that my
50 and 100 mm lenses will meet my needs exclusively and, therefore,
these lenses would be the intended target for the skyglow filter.

       Any other leads as to how you may have dealt with sky fog and
light pollution in photographing satellites and iridium flares would be
appreciated. I have consulted a couple of bibles on astrophotography and
there is absolutely no mention or reference to satellite photography!

Anthony.
