Here's a shot of the sunset over Lake Erie when I was in Ohio a couple of weeks ago. This is actually a very tiny crop of a much larger picture, but I wanted to show you the mirage effect that occurred out over the lake. That's not a cloud in front of the sun creating that line, it's layers of different air temperature over the water, creating odd reflections and refractions (same things that cause the not-mythical Green Flash!). I wish I'd been able to get better pictures of it, but there was a train going by behind me, and I wanted to get pictures of that, too. So this was about the best I got of the sunset. This was shot with that fancy lens I rented, and it's cropped to well within an inch of it's life and it still doesn't look too bad.
