Hello,
Don Goldman is almost my neighbor...
if you don't know much about him, suffice to say he has degrees in
spectrometry... he runs a business that devotes its time to chemical analysis
via spectrometry... so it's a natural for him to be interested in the true
"performance" of color filters... he is an avid amateur astronomer and CCD
images from his back yard outside Sacramento.
He was very concerned
that his presentation be as accurate as possible and we spent considerable
time going over it... all of what he says about the "true" color response of
various filter sets seems to be accurate, especially what he says about the
SBIG set... I am finding that the 1:1:1.6 is wishful thinking... it's more
like 1.2 Red, 1.0 Green, 2.0 Blue. This is close to what his analysis came up
with.
For what it's
worth,
Tony
