Thanks for the reply's guys. I tried autoguiding using PHD, but it lost the guiding star every few minutes. I think this is due to not having the mount perfectly polar aligned.
I ended up manually guiding the scope using the GPUSB nudge utility while keeping an eye on the stars on the PHD window with the grid overlay. It drifted then got nudged back quite a number of times, resulting in the wobbly stars.
The wider moon image was the best one of a series taken with a Canon 7D, whereas the close-up was with a DMK41 Imaging source CCD cam. I think the 7D image looks way better and real then the Registax 6 stacked close up. I did go a bit too hard with the "enhancement" since the viewing conditions were better on the day I used the 7D.
The Saturn was using a Celestron NexImager, photoshop tweaked and cropped where M20, Jewel box and M104 were taken with a Canon 40D.
The "deepsky" pics were limited to 2-3 minutes per exposure due to the light pollution, then I had to adjust the levels in photoshop before stacking them manually. The blackness "milked" out quite fast.
Can't wait to give it another go...
