What light pollution for milky way shot?

According to this map:
Light Pollution map

At my house i have 30 light pollution while a few miles away it's only 1
IS it enough to photograph milky way? IS this map accurate?

That is a really cool map! Thanks for sharing that..very interesting.

Where I live in Vermont, I can see the milky way with my eyes, its so clear. According to the map, the light pollution where I am is just under a 1. So I'm positive you can get a nice shot of the milky way where you are.

What camera and lens?
Is your near by dark site a 1 - 3 or a 0.4 - 1 on that map.
Last night I had my telescope set up in a 0.4 -1 site.

Even at a dark site, to image a portion of the Milky Way you'll need to make an exposure of some seconds.
The earth is constantly rotating on it axis so after 12 to 15 seconds stars will start to leave trails.
One way people avoid start trails is to make a series of shorter exposures that are later 'stacked' using software to 'build' a final image.
A free application for stacking astrophotos is DeepSkyStacker.

To avoid start trails when making wide-field astrophotos people use a motor driven camera mount that can counter the earth's rotation.
Using a motor driven mount, any foreground in the shot will also blur as the mount tracks the sky, which is why some camera mounts have a 1/2 speed setting.

Here are 2 other motor driven camera mounts.
One better, and one not as good as the first one I linked to.
I just got a SkyTracker but last night's observing list didn't include making photos of the Milky Way.
