RE: [APML] Transit exposure help

["Jeff Ball" <jeffball@astro-photography.com>]

Whoa,
You're going to Myrtle?  Me, too.  I am planning on going over Sunday
night and stay in Huntington Beach State park if I can.  Drop me an
email if you want to get together!  I will probably go the pro photoshop
in town to pick up some 120 print film if I think that will work best.
I hope to develop my slides at the shop from Monday morning's test
shoot.  The weather looks very promising right now.  I think we will
benefit from shooting through the thick atmosphere on the horizon that I
just can't get here in the mountains.  

Best regards,

Jeff, I sure hope someone posts a definitive answer because I would be
interested myself. I am heading to Myrtle Beach, South Carolina Monday
night to camp with my wife and won't have any time to get a test in
before Tuesday morning.  I will be shooting with a Nikon N80, Sigma
300mm f5.6 and Kenko 2x TC equaling 600mm @ f11.  My original thoughts
were for Velvia 100 but some members here have me swaying towards print
film.  In reality I will probably carry Velvia 50, 100 and Kodak Supra
400.  I have a film picker and the N80 has served me well for mid-roll
changes so I will wait until the last possible moment to load up and
then most likely switch.  Regardless of the film choice, I plan on using
the spot metering setting and the auto bracket feature of the N80, just
not sure how many stops I should bracket over and under. 

Same idea, bare lens at first and then solar filter (I have both the
Baader and Thousand Oaks films).  According to my calculations I will
gain 5 minutes of viewing time by driving the 130 miles to the coast. 

Not sure if you have any ND filters but they would be a good way of
stopping down if you run out of shutter speed (the old 2 stop polarizer
trick doesn't work when looking directly at or away from the sun).

Maybe somebody like Jerry could show us the way :-)
