I am going to be going up to the space center or close to it so that I can get some pictures of the Space Shuttle going off at night time.
I will be using a Sigma 70-200mm f2.8 with a 2x xtender to bring it up to f5.6.
I was wondering if I should use the bulb feature for the camera to get a long exposer. The shuttle rockets light up the whole sky almost like a sunrise.
If any one could direct me on this so that I can uptain a good picture please walk me through with what I should do.
Thanks
Scott
