I have just got a test film back from Boots, best results using Baader
Astro-solar film over the aperture were ...

1/250 sec with a f8 mirror lens and 200ASA Kodak colour film. Tripod and
cable release are a must if lens is 200 mm or longer.

Best regards

Have you had a good sky transparency during your tests? According to
Espenak's table of exposure
http://sunearth.gsfc.nasa.gov/eclipse/SEmono/TSE2006/TSE2006tab/TSE2006-tab23.html
the best timing with your system should be 1/1000 of sec.
I did some tests during a very bright and clear Saturday with Baader ND 5,
Baader ND 3.8 and Thousand Oaks Black Polymer ND 5, using a Tamron 500 mm
f/8 and 2x multiplier lens, on Fuji Sensia film 100 ISO. Best results were
1/250 for Baader ND 5, 1/125 for Black Polymer and 1/2000 for Baader ND 3.8.
Unless you were using a very old Baader ND 6.0 which was available for the
August 1999 eclipse...

As for my own attempt to record the eclipse, I would try with the above
equipment and Thousans Oaks Black Polymer shooting three images for each
time in the range from 1/60 to 1/250 and would try the sequence with a 135
mm with same Black Polymer. Ah, the site: as Salloum, Egypt.

Clear skies,
