I've long been interested in astrophotography, and it was one of the primary reasons I purchased my Canon 450D about 15 months ago. I've been working on getting milky way shots for the last 6 months, and finally feel I have the hang of both the theory and application.
I am interested in taking time-lapse short-exposure (25 seconds) shots over a period of several hours (possibly a full nights worth, 8-10 hours), in an effort to put together short movie clips of the stars and milky way moving across the night sky. I've found numerous intervalometers, including the
Canon TC80N3, however they all seem to be for the XXD and XD series of bodies.
Are there any intervalometers that will work with a Canon Rebel XSi 450D body? Will the TC80N3 work? Or is time-lapse photography simply not a capability of Canon's entry-level bodies?
