I would like some advise on taking pictures of the moon and stars. Last night I went out and took some pictures and they did not turn out that great. I set my camera to the " bulb " setting and my ISO at 200. I left the shutter open for between four and 10 seconds. The star shots turned out better than the moon. I kept getting a red spot on the moon shots and it appeared the stars moved.....( do they move that fast ). I would like to try again. Here are my options for Lens's. Nikon 28 mm 2.8, Nikon 85 mm 1.8, kit lens 18-55 mm, kit 55-200 mm and a 300 mm Tamron. Which of these would be my best bet for lens? Also shutter speed and ISO assuming it is clear night. Thank you for any advise.
