What's up with the Nikon?

On the shuttle launch, I took a lot of pictures of bright objects;  rising sun, main engine ignition, etc.  On more than 1/3 of the images, there is a reflection/ghost image that mimics the shape of the bright object only inverted.  I've never had this happen before, and I'm a bit miffed.  It feels like the light is being reflected within the lens and causing a second image.  The Nikon web site says the lenses are specifically built with some fancy technology to prevent reflection.  I'm taking it down to the photo store tomorrow to have them look at it.  Any suggestions?

My point about trash.

I spent an hour yesterday picking up trash with the Cub Scouts at Daffin park.  First let me say that it wasn't as trashy as I expected, however it did prove my point about water bottles.  Of the items picked up, 8 out of 10 had something to do with a plastic water bottle.  The lid, the wrapper, the little safety lock ring thing below lid, and of course, the whole bottle.  I avoid using plastic water bottles for the sake of trash, but sometimes it's inevitable.  One of the biggest purchasers of water are those that "prefer the taste to tap water."  I agree that tap water can taste 'off.'  I spice it up with the Crystal Lite and Gatoraid single serving pouches.  It helps the liquid go down.  My over priced stainless steel water bottle has paid for itself multiple times over, and who knows how many plastic water bottles are not in the trash.  Off soap box.
