All excellent and valid points Tom, I am an admin on a d-board that
has nothing to do with astronomy or photography and the noob
questions do tend to repeat ad nauseum.
That being said, there will always be lurkers who will never post and
will head straight to the FAQs or reviews.
Anyway, I'm goung to be compiling a list of the questions and
attempting to answer them. I have also contacted Phil Askey of
dpreview fame to ask his permission to re-purpose portions of his
300D and 10D reviews with and eye towards astrophotography.
If you *do* have any questions about these specific cameras, DSLRs in
general, astrophotography techniques using SLRs, please do post them
in this thread... It'll probably take me a week or so to come up with
the first draft. If there is someone out there who is using a 300D
for astrophotography, kindly let me know if I can call upon you to
assist with reviewing the doc so I can ensure its completeness and
acurately.
Thanks,
Tom Goode
