No, this isn't some strange nebula in a galaxy far, far away, but a rather interesting shot from the Bettendorf fireworks display, which was great as always. Click to view larger.
Rather than plop a bunch of pictures in this post, I tried creating an album online and threw a few up there.
Obviously a lot is lost when you see them at small size, but here's a preview. A double click on the slide show will open up the gallery. Once there you can enlarge the pictures (look for the size icons in the upper right) and play them as a larger slide show if you wish.
Let me know how it works for you.
And as a bonus, here's some video of the Grand Finale.... it was quite impressive. (Turn it up loud for full effect.)
