Hi. After doing prime focus with my Nikon F, I decided to get into the
21st century. Bought a 350D and got a Canon bayonet mount for my
Lumicon off-axis easyguider. Last weekend I tried out the camera on my
24" dob w/ equatorial platform. Just used a simple shutter release, so
the camera was not hooked up to the laptop. See images:
http://www.stargazing.net/mas/pics_allen/photos.htm
Had the camera set at ISO 800, noise reduction on. I do like that
automatic dark subtraction. Yes, for a 2 minute shot you have to wait 2
minutes for the dark frame. Still, seems quicker than having to go back
afterwards and manually take/subtract dark frames.
Question. In the Camera, each image has it's ISO and the exposure time.
Is there any way to transfer that information when the images are
downloaded to the computer?
This is my first attempt with the Canon and I was impressed. Haven't
even tried RAW images or short shot stacking. I hope to go out tonight
and try another set of exposures. Any and all advice would be greatly
appreciated...Dennis

That information is attached to the picture file in the EXIF header.
When you transfer the picture file to the computer the EXIF header
information goes with it. You can view the EXIF header information in
the picture viewer. The EXIF header also includes the time of day,
based on the clock in your camera, and with EOS lenses the focal
length and f/stop.

So the information is already in the jpeg, just have to access it? I
haven't installed any of the Canon utilities on my XP, just imported the
images with the USB connection. The XP picture viewer doesn't seem to
display that info. Guess I'll have to install the Canon utilities on
the XP...Dennis

In the Windows XP picture viewer, right click on the image, left click
on properties in the menu that appears, left click on the summary tab
and left click on the advanced button to see what comes up. The EXIF
header is more or less a standard and XP knows about it.
