>>2944374And this is a regular 30 second exposure of the Andromeda galaxy, (you may notice the stars are blurry due to the trailing) So 30 seconds was clearly too long to prevent a nice clear picture, but too short to gather enough light. So Instead I took multiple pictures of a shorter exposure. As far as how many you wanna take, it depends on the type of gear you have and the subject that you are shooting. Just play it by ear.
