809.7 second exposure (or 13 minutes, 29.7 seconds) of the night sky, with a tree lit by a single candle in the foreground. I would have improved on this shot with a few more takes, but at 15 minutes per shot at 1:00 AM, I got tired (and cold) quickly. Editing was Noise Reduction, Sharpen, Color Balance, Brightness and Contrast, Resize, and Crop.

A terrific star trail. I would say you went far beyond the 30 seconds here. I will give it a guess at about 30 minutes or more! lol. Nice that the tree wasn't moving much. I love dead trees to find for these shots because leafy trees seem to blur a lot but yours is really nice!
A couple of things to note if you haven't already done this... use the self-timer to avoid your hand causing camera shake, weight the tripod to prevent wind-shake...
You might also consider a bit of curves work to shift that yellow out of the tree...
Nice stuff though... if it was around here, I'd have about 4 stars in the pic...
