I am trying to photograph the Milky Way on my EOS 5D Mk2 . In manual on my EOS700D when I turn the main dial I can brighten up the Liveview in order to zoom in x10 and focus on a star before taking the picture. On the 5D the LCD stays the same so a black screen at night and trying it now the Liveview image doesnt brighten or darken. Would appreciate any help getting it working. Thanks.
