To: All who responded to my initial post
Last night the sky was clear and I, with some help, figured how to
take time exposures with my Canon SD1000. Since I was interested in
imaging Vesta, I pointed my camera, on a tripod, at Jupiter and took a
15 sec exposure. Jupiter and Antares were obvious on the image. A
few faint objects also were in the image. I'm trying to identify the
image scale so that I can iI can identify the other objects by
comparison to a star map.

Chris:
My first image with my Canon SD1000 got down to 4.5 magnitude. So I
didn't capture Vest at about 6.0 magnitude.
Thanks for your input.

Chris:
Thanks for the idea. I hope the sky cooperates.
I obviously need and want a better camera to do what I'm doing but
I'm not interested intaking images at the prime focus of telescope.
All I really want/need at this time is digital SLR that allows for
time exposures of 30 sec to a minutes. I have an equitorial drive
that attaches to a regular camera tripod and to which you can attach a
camera.
What is a low cost digital SLR that has a manual time exposure feature
(bulb) with other features unnecessary?

I like the Canon DSLRs for casual astroimaging (and for general
photography, as well). You might consider a 300D (Digital Rebel). This
model is obsolete (although quite full featured), and can probably be
picked up used for $300 or so. If you want new, look at the 350D or 400D
($600-$700).

Try taking images each night for a few days. You can then compare them
visually, or blink between them. If you edit the images (or shoot them
carefully) so that they have the same orientation, you may be able to
pick out Vesta by its movement from day to day.
