They're excellent images.

If you're using APT or BYE to control the camera then you can get it to lock the mirror up a couple of seconds before the exposure.  That allows you to take exposures of 1/500th or even slower which gives you a bit more dynamic range to work with.  (Trying to reduce the exposure time that far without the mirror lock-up caused ghosting in the images for me where the mirror movement had jolted the camera slightly.)
