I'm having some trouble getting the results I'm after, and I'm not sure why.

These shots were using Av and Manual mode, ISO 100, f4.0- f5.6, 30 second exposures.

What can I do to make the edges more crisp? I'm shooting with a 50D on a tripod with 2 second timer, Tamron 10-24mm.

Thoughts? Criticisms? Suggestions?

Obvious solution comes to mind: shoot at f/8 or higher and in bulb mode (you'll need a release or, as I discovered desperately one evening, a rubber band and a pebble!) as you'll be shooting at > 30s. Also, make sure you have a steady tripod. If you can find at least one portion of your images that are super sharp then you can cross shakey tripod off the list of suspects.

I like 3 best--might like to see it rotated CCW a little and the foreground filled a little.

Focus is a huge issue. I have found that what I thought was in focus was off. I now use Live View exclusively. I have also found that a cable release is necessary and waiting for the tripod to get steady before firing the 2 second timer. With a short lens it's less of a problem. Wind is another factor. Not so sharp glass is another issue. There are lots of ways to make less than sharp images.

Not everyone has live view;)

2 second timer, or having 2 second timer with the mirror lockup on should reduce a lot of the shake.

I agree. If you do not have a release, use the timer. I almost always use mirror lock up when shooting evening low light or night shots. Good luck......Shawn

As someone earlier said, shoot a smaller aperture f/8 - f/16 depending on which lens you're using and a longer shutter...try around 11sec and see what you wind up with.

Be sure to enable mirror lockup, unless using Live View where it's on by default.
