Hello,

I am considering a CCD camera mostly for my 12inch Dobsonian so I can capture images of the moon, sun and planets with maybe a few bright clusters and what not if I am lucky.

I am considering a few options.

At first I was thinking of getting a "The Imaging Source DMK 21AU618.AS" but I am thinking of getting one of the higher models that have a larger sensor. The DBK 51AU02.AS has a large 1600 x 1200 pixels compared to the 640 x 480 of the DMK21.

While the DBK 51 may be a bit of overkill it would give better results and having a larger sensor would make getting wider field of views a bit more possible. So I could get the full moon in one shot, or sun for that matter which I would like to be able to do.

Plus I can now afford the 51 and I could use it later down the track when I get a more astrophotography orientated telescope.

One thing that confuses me about The Image Source cameras is the difference between the DBK and DMK models. From a look at the specifications they are identical. Any ideas on the difference?
