Post correct exposure for stars
Howdy.
Yes: total newbie here. I live in the desert with very little light pollution so I'm going to try to capture some images with stars and galaxies this week. I don't have a clue where to begin on exposures. I do have a 5DmkII so I'm guessing I can start with very high iso. And I do have a 2.8 lens (may need to investigate a faster one eventually). Any advice on where to begin for a proper exposure? Thank you.

There's a great chart here: viewtopic.php?f=17&t=311

As it says just double times for milky way shots. I'm shooting a 7d @f3.5 my best exposures at 3200 are about 28-30 seconds. Don't be afraid to push the shutter speed a little longer, I don't usually get much movement in my stars until 25+ seconds @ 18mm.

20 secs at f2 at 2000 ISO is my default starting point for star lapse. To get the cloudy milky way look on a moonless night 30 secs at f1.8 at 3200 ISO does the trick using a 5DII :-)
