[APML] Quebec Aurora

[George Anderson <georgea@cam.org>]

Saturday night myself and about 30 others drove to a dark sky site about
4.5 hours north west of Montreal. The site is an inactive runway in the
La Verendrye Park and most had gone up to do some deep sky observing
while I planned on trying to get some widefield shots that were not in
the oblong blob catagory.
The shots were on Supra 400 with a 28mm lens at f/3.5 and the prints
were scanned with a flatbed scanner at work (my sprintscan should arrive
this week) which I have discovered someone has gotten a fingerprint on
the inside of the glass plate.
Results can be seen at http://www.cam.org/~georgea/Aurora.htm 
The negatives are very much on the thin side, I hadn't realised how much
the light pollution from home helped sensitize the film on my exposures
last November 5th.
Longer exposures would have resulted in much greater blurring of the
auroral light. So although ISO 400 was good from removed
suburban/semi-rural house last year, I would go with ISO 800 when
shooting from a dark site.
