[APML] M13 with Canon 1Ds

["Mike Unsold" <mike@mlunsold.com>]

Clearer skies and warmer temperatures are starting to allow more
experimenting with
the Canon 1Ds. The following image is the sum of 22 2 minute exposures at
ISO 250
with noise reduction on. More image capture and processing details are
available under
the image in the following link:

I am trying to color balance the 1Ds and your comments are most welcome.
It appears that the Canon 1Ds has the following white balance factors:

H-alpha = 3.65, Red = 1.02, Green = 1.0, OIII = 1.043,
H-beta = 1.0, and Blue = 1.01. The factors are based on exposures
of a white card and uniform light gray cloudy sky.

Mike
