Images of what Jackson?

I have a few cameras, and find that they're all good at their own things. Of the two DSLRs I have, my Canon 350 is probably a little better for general deep space photography, whereas my Nikon D40 murders the Canon for Lunar photography. Both are set to their default white points. The main issue on Nikon cameras such as the D40 is that the cameras internal software tends to be set to consider some smaller low-magnitude stars "noise", removing them (un-handily) when the image is pre-processed and written to the storage card. This can be bypassed by turning off the camera as soon as the exposure is done, because this forces the software to write the raw image data to the card before pre-processing can take place. A bit of a pain, but doable.

Here are a couple from my D40 a while ago. Processing wasn't fantastic by any means, but it shows that the D40 will work admirably. Please excuse the JPG artifacting due to compression.
