D3 vs D300: Which is the better Nikon camera for shooting a lunar eclipse?

The technical detail covered by the replies to Neil’s thread is way over my head, though it makes for interesting reading.

Neil concludes that the more suitable camera is the full-frame D3 because of its (assumed) two-stop noise advantage over the D300 (APS-C DX crop camera), which is crucial in ensuring that the exposure time is kept as short as possible in order to avoid motion blur from the movement of the moon.

Additionally, Neil says that the camera should be set at approximately 1/1000th of a second, f/8 and shares a sample image from the October 2004 eclipse.

For this particular type of photography, the D300’s relative strength in reach and pixel density isn’t advantageous.
