As this if my first shot at startrails, I would like like your honest C&C.
Canon 6D @ ISO 1600 w/24-105L @ 24mm f/4.
254 30sec frames ~2 hours.
I walked a few KM into the desert to get away from the light pollution. I guess it didn't really work as you can see in the left side of the frame.
I pointed a small LED flashlight at a rock that reflected the light at the tree.
I shot RAW. LR4-> JEPG, then I ran the JEPGs through Startrails.
