Beautiful shots Wei-hao, especially the Milky Way! I didn't know
E100S was that good, wow. By the way, do you ever take a bad picture? : )

Hi,
Personally I'm a big fan of Kodak E100S. I
believe 99% of astrophotographers
in Japan are too. The biggest
quality boost on deep sky photos in the 90s was
brought by E100S.
Interestingly, this only happened in Japan. People in the
US seemed
to ignore this great film for years, even after E200 appeared.
Anyway, E100S was discontinued in 2003 and the golden age had
passed.
Just to show you a few pictures taken by this awesome
film:

At
this moment, the most important ASA100 films are Provia 100F and
Kodak
E100G. They are important because they are the only color films
that are
available in both 120 and 4x5 format and are "potentially" good
for deep sky.
Their true deep sky performance is
controversial. Gary just mentioned that
Provia 100F may not be
excellent on DSO. On the other hand, I had seen
many excellent
Provia 100F images taken by Japanese astrophotographers.
Many of
them are 4x5 shots. A Japanese magazine tested E100G and
reported
exactly the same thing as Gary commented on Elite Chrome 100 (and
also
similar to my experience on E100VS). On the other hand, Garth
Buckles posted
a great image a few months ago taken by E100G:
http://www.ocastronomers.org/astroimages/album.asp?pic=NA%20neb%20OCA%20site.jpg&cat=Wide-Field%20Photographs
I
don't know what conclusion I can make about Provia 100F and E100G.
Perhaps
films are so sensitive to environment (humidity, temperature etc)
so
different people get different results?
In addition to Provia
100F and E100G, there are limited pictures showing that
Fuji Astia 100F,
Velvia 100 and Velvia 100F are all good (or at least OK) for
deep
sky.
Cheers,
Wei-Hao
