[APML] Zapping moonlight glow with PS

[Emmanuele Sordini <vega@ulisse.it>]

Hi all,
last week I took some nice shots of comet I-Z with a 200 mm telephoto lens 
and E200 film, where the comet shows off a tail about 4.5° long (as 
measured on the frame).
In spite of the exceptional sky transparency due to a very dry (down to 15% 
RH!) NW windstream, moonlight inevitably shed all over the pictures, making 
the comet's tail less noticeable.

Anybody know of any digital trick (Photoshop and the like) to dim the 
moonglow, darken the background and theregfore make the wispy comet's tail 
stand out?

Thanks in advance,
Emmanuele Sordini
