looks like I found the answer.. dropped the image into this new enlarging app i just got, and it was able to give us a better look.

I thought for sure it would have turned out to be the new 5D Mark II up there.

I can confirm that these dots are ET and some of his gang - parked up and watching us from afar

I can also confirm that they have been reading these posts on *gww.fm.con and have delayed their arrival in order to enjoy the high levels of creative answers

Keep posting or we are doooooomed

These are defiantely caused by sensor error. This cosmic ray thing is hilarious though.

The white pixel coming from the tree proves it IMHO...stars dont grow on trees.

It's hot pixels. Depending on the camera (New models are better) they start to appear after 5 minutes or so exposure on digital SLR's. I have done some tests on my cameras with the folllowing results :-

EOS 10D - Unuseable for exposures of more than about 5 minutes due to a combination of noise/hot pixels and amplifier glow.

EOS 5D - Ok up to 10-15 minutes.

EOS 40D - OK up to 20 minutes.

Hot pixels can be minimised by dark frame subtraction.
