As far as other (moon, planet) shots go, I've been using a CCD imager with registax, though I did not know that I could stack JPEG images in there as well, I suspect that I've been blind. 
That's just the sort of information I needed, though, and I'll be sure to try using registax next chance I get for stacking regular images.
Thanks! |
I suggest getting a remote--the cheapest is basically a hand-held button with a wire to the camera, and if the camera has a "bulb" mode, you can either hold the button in, or with most remotes, it has a lock to lock the button in, and you release when time's up.
Even if you don't want to use the bulb mode, pressing the camera's own button directly starts it shaking, and that really screws up images!
