Wanda, this one was shot, of course, inside the dome. It's very dark in there so I increased my ISO to 1600 and was was shoting wide open at f5.6 and slightly under 1/250 and 1/300 shutter speed. My focal length was 400mm. But with the image stablization I get 2 to 3 stops more. The bad thing is if you try to enlarge this to an 8X10 you will see noise do the the high ISO of 1600. There is a light blur but no bad. I also up the brightness in Photoshop by about 2 stops.
