Re: [APML] what film on comet

["Chris & Jennifer Cook" <ccjd@ix.netcom.com>]

I shot the Fuji Press 800 w/ the 4th layer for the Leonids and got excellent
results.
See: http://www.abmedia.com/astro/misc/leonid01-fireball.html
Also check out Stan Richard's great aurora images.  See:
http://www.geocities.com/stanzman_2001/Aurora102101.html
It just does not have any red response for faint emission nebs.  There are
many other objects in the sky that the 4th layer films can be used for.
Those that have recently posted saying that the 4th layer Fuji films are
worthless for AP are incorrect.  These films are only worthless when
shooting faint red emission nebs.
