[APML] Speaking of E100 and Velvia

[Robert Reeves <reeves10@swbell.net>]

Greetings,

A fortuitous topic...  I have been asked about E100S film by a rather
high-flying astrophotographer.  In fact, he is so high flying that he will
be aboard the ISS with the next crew going up in November.  Dr. Don Pettit
will fly to the ISS in a few weeks and he is an astrophotgrapher!  About a
year ago he contacted me and we started chatting about astrophotography
opportunities from the space station.  He paid me a great compliment when he
said he regarded my book Wide-Field Astrophotography as the only book he
deemed interesting enough to haul back and forth between Houston and Star
City, Russia.

Anyway, since the ISS flies through a low radiation environment, they don't
take up any films in the 800 speed range because of fogging.  Don is going
to try some 800 speed anyway and attempt to shield the film with water
packages until getting it back to Earth.

Traditionally, the use E100S and Velvia in their film cameras in orbit.  As
an astrophoto backup in case his 800 speed is fogged, he wants to use some
of the E100S for astrophotography.  He asked me about the suitability of
giving this film a two stop push to get more out of it for astrophotography.
I have always pushed E200, but never have used E100S.  Can anyone tell me
about pushing E100S for astrophotgraphy?  Good, bad, indifferent?

If launched on time, Don will have a stellar view of the Leonid storm next
month and actually see the meteors from above!
