RE: [APML] Expired Film Replacement

["fl.lusen" <fl.lusen@verizon.net>]

Geoff,

Thanks for the information.  For now, since time is of the essence I am
going to take Bill's offer.  What I may do though is alternating shooting
the same subject both piggy back and prime focus using both films, my PJ 400
and Bill's Supra 400 and see what the comparisons are.

I definitely need to get out more and start experimenting with other films.

Does it never end?

Will try to have as much fun as the law allows at TSP.

Fred

 Hey Fred...

     Color print films suitable for astrophotography are indeed in a grim
state. The aging PJ 400 will record HII nebula with a reddish-brown color,
as Phillip mentioned. Here's an example from last year with the PJ 400:

       http://home.att.net/~astropix/M42_135mm.html

     There are a couple of possibilities, however. Fuji's 'Super HQ 100' has
shown some capabilities... but not enough usage has been shown here at APML
to make a reasonable assessment. This film is one of Fuji's low-end consumer
films, isn't even mentioned on Fuji's website, and seems to be made just for
Target and Walmart. I found some on e-bay for < $1.00 a roll! Here's a shot
a did with this film a couple of years back... go to:

      http://home.att.net/~astropix/ngc7000_135mm.html

... the above image could use better processing, there's more in there than
what you now see. Of course, with a speed of ISO 100, fast focal ratios will
be best, but the film also has fine grain because of it's speed. Needs more
tests, but seems to show promise... didn't Tony Hallas get a couple of nice
shots with this film?

     Koncica 'Super Centurion', both 400 and 800 speeds shows great promise
as well... I'm crossing my fingers for this one when my 'Supra' stash runs
dry. WH Wang has a remarkable shot with the 400 speed version of this
film... see:

      http://www.ifa.hawaii.edu/~wang/gallery/picutres/m16_to_24.htm

... availability seems to be an issue for now... this version of the film is
still fairly new, at least for US consumers. You should probably get some of
the good 'Supra' from Bill for your TSP outing.

 Have Fun At The Texas Star Party !!!
