exif on 1st one:
Exif Sub IFD
* Exposure Time (1 / Shutter Speed) = 649/10 second = 64.90000 second
* Lens F-Number/F-Stop = 80/10 = F8.00
* Exposure Program = manual control (1)
* Exif Version = 0221
* Original Date/Time = 2007:07:28 09:15:42
* Digitization Date/Time = 2007:07:28 09:15:42
* Components Configuration = 0x01,0x02,0x03,0x00 / YCbCr
* Compressed Bits per Pixel = 4/1 = 4.00
* Exposure Bias (EV) = 0/6 = 0.00
* Max Aperture Value (APEX) = 42/10 = 4.20
Max Aperture = F4.29
* Metering Mode = pattern / multi-segment (5)
* Light Source / White Balance = cloudy weather (10)
* Flash = Flash did not fire
* Focal Length = 310/10 mm = 31.00 mm

it really helps to have a remote for night shots, camera shake is a killer. and a fast lens is usually a pretty good idea also. night shots like the 2nd one should have a full open aperture( even though i used f8) as you dont need to control the DOF as much because the light of the moon almost does it for you. the 1st shot however i used f8 for a balance between speed and DOF.
just experiment with you camera in manual mose as much as you can, the better you know your camera the better your shots will be.
