Here's my first attempt at star trails. This picture is made up of sixty 30 sec exposures with a 2 sec interval delay using the intervalometer in my K7. Now that I'm comfortable with the technique, my next try will be with hundreds of exposures and a 2-3 hour acquisition time. Blending of all the images was done using "StarStax" software. It was still in the 60's* last night - unbelievable beautiful weather for this time of year.

Very nice, I would use a stronger silhouette than the tree though a building perhaps?
