clean your sensor!
Try adding some sharpening, maybe a little desaturation

Still nice though.

Really- what makes you say that? I'm not saying your wrong, just trying to understand what to look for.

Is this better?

in the first image. If you look above the tail. You will see a large black spot. Then if you look on the rigth side of the image and inch or two from the top. You will see another spot. Not as dark as the one over the tail. Thats sensor dust

okay- I saw the big one, but don't see the other. I don't see it on recent images. How can you tell sensor dust from a spot on the lens, especially at this range?

Hi Geoff
An easy way to help see where dust spot are on such an image is to use the histogram equalize feature on your editing program , I sometime use "negative image" or the " chrome" filter too.

I use Photoshop Elements 3.0 for now; until my photo skills exceed the PE functions. I'll try that when I get home. Thanks

Typically, unless its a very large piece on the lens your will never notice it. What you can do is take your camera. Put in M mode. Turn the aperture as far as it will go (f-32, anything hire than f16-18... Shoot at white wall or clear blue sky. (you don't even have to focus your camera). Then upload your image in PS view at 100% and that will reveal all your sensor dust particles
