that is very pretty Robert

Out of curiousity, why 611 seconds instead of 600 or 630?

Digital cameras look about to kill the one shot color CCD market from
results like yours. How does the modified camera work for ordinary
snapshots? I'd never get such a camera by my wife unless it could pull
double duty. How do you find focus with such a camera? Does the
viewfinder blow up the image so you can see enough to focus on the view
screen? When I've tried to take planetary shots through the old Cannon
my wife uses the view screen was way too small to tell good focus, even
when I used the magnify function. Only way I could make it work was
connect it to a TV and use the magnify mode. Then it was large enough
to sort of tell when it was in focus. Still I'd take a range of focus
positions to get one or two that were sharp. Focus masks didn't seem to
work either. I just couldn't see enough in the view finder to tell when
the three images merged. It would look good until I took the photo.

That came out very well. Good color balance.

Very nice shot Robert. I tried this object once with an unmodified EOS300D
and it was quite hopeless (or crap to be more precise).

Richard,

I use a stop watch, but I use the camera's info on exposure time.

Rick,

For focus I have settled on the Hutech knife-edge focuser. I have had
good focus using Jupiter, Saturn, and the Moon. Focus on bright stars
is hit or miss. My 300mm f/4 Canon lens will auto focus on bright
stars.

The Hutech modified Canon 350D camera, with the extended red filter,
is said to be able to take normal photographs using a modified white
color balance. I have not tried this, so I do not know how well it
works.

I used a ronchi grating for focusing, many knife edges, in my film days.
Though to set it I had to use a knife edge in the film plane then
adjust the ronchi grating to the same distance. I assume Hutech matches
it to your camera's setting at the factory. I found it a pain in some
eyepiece positions on my Newtonian but it did an excellent job.

Thanks for the info.

Rick
