Another feature I like is Upright. It's found in the Lens Correction section of the Develop Module. What it does is automatically straighten images. There are a number of methods to choose from and some work better than others, depending on the image. But in my testing, I find it to work rather well, especially on interiors taken with wide angle lenses.
Also be on the lookout for more a sophisticated spot removal tool called the Advanced Healing Brush. No longer are you restricted to circles. You can now click and drag to create non-circular healing areas.
There's also a new editing brush. In addition to what we're used to: Graduated Filter and Adjustment Brush, there's a new Radial Filter. It can create circular and elliptical shapes to apply adjustments to. So you can effect changes to the elliptical area chosen or you can invert the filter and apply changes outside the area chosen. Pretty cool.

During our Arches workshop, we spent a very pleasant evening at Double Arch making moonlit landscapes that contained star points, star trails, and fun light painting. The night was warmish, the sky cleared up, the company was great, and it was lots of fun. The only thing missing was the above mentioned bottle of wine (and if we had decent workshop leaders, we probably would have had that too).
Needless to say (I hope) you'll need to experiment a bit with your ISO settings. You'll need higher ISO if you plan on including any landscape in the image. If you just need silhouettes you can get away with lower ISO. If you have a full moon, you can use a lower ISO. But hey, you've got an LCD display and a histogram on your camera so experimenting should take very little time.
The star trails image accompanying this article is from a series of five minute exposures, blended in Photoshop. To get a better look, click on the image. I could have use a program called StarStax but since I had relatively few images (something like eight or so) I merely selected them all in Lightroom and chose Edit>Open as Layers in Photoshop. I then just changed the blending mode on all the layers to "Lighten." This basically lets only the star trails show through from the layers beneath the top layer. Each layer has the star trail in a different position and by blending them using Lighten, the final image shows one long trail.
