RE: [APML] [OT] full frame DSLR

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

Hello Wei-Hao,
I think the Canon's have long been regarded as excellent with regards to
low noise.  My brief experience with the Canon 10D has shown the trouble
with amplifier glow.  I think this is the biggest culprit to getting
evenly illuminated backgrounds without clipping the data.  I could be
wrong, but I believe the only full frame camera for Nikon is the Kodak
DCS 14n.  Online noise tests at Luminous-Landscape have generally shown
the Canon CMOS to be cleaner at the higher end of the ISO range than the
CCD chips in the Nikon.  I wish I had a full frame DSLR to share my
experiences with you:-)  Here is the info:

Hi,

A professor in our institute came to me and asked for advise on 

Among those full-frame DSLRs (EOS 1D Mark II, EOS 1Ds, Nikon D...?), 
which one is best for long exposure?  He doesn't care much about 
H-alpha sensitivity.  He will use this camera to evaluate the 
light pollution in Hawaii.  (Yes, we do have light pollution.)

Any suggestion is appreciated.

Wei-Hao
