Big Dipper at Silver Lake

I went up to Silver Lake Saturday night to shoot the night sky. I shot this looking North
West, you can see the big dipper. I shot it at ISO 3200 in Manual and bulb for 84 sec at f/4. I used a 20 million candle power flashlight. I blew out part of the grasses but recovered most of it in Photoshop. It was almost 11:00 PM when I took it. LYLE
