[QUOTE="Dave_W, post: 156247, member: 9521"] I think we have to rule out anything within the camera since it didn't do it with the other images. And we can also rule out the shutter release stuck theory since light did indeed make it to your sensor (something that wouldn't occur if your mirror/shutter were stuck somehow). And mirror-slap is out of the question since this occurred well into your exposure and not at the beginning. After the mirror is up there's no other moving parts in the camera during the exposure process that would account for any movement. That leaves only camera shake of one form or another as the cause. Now whether it's from your USB cable or wind or even the focus ring on the lens slipping, that's a tough call. But the good news is that it happened to only one of your images which means it's a fluke rather than a reproducible problem. Try repeating the star trails shot and weigh down your tripod set up with a bag of sand or do like I do and hang a bag of pennies to your tripod (assuming you have the weight hook on the center post) and see if this issue repeats itself. Btw, welcome to Nikonites. [/QUOTE]
