So I'm trying to use a Nikon 1 V1 (yes I know it's an ancient camera!) for taking long exposure photos of the night sky. I have a wide angle lens and have set the mode to M; using a remote in 'time' mode I can take long-exposure pictures inside in the light fine, but when I go outside, point the camera at the night sky and press the remote the shutter doesn't open (all I get is a little red outline box on the screen). I think the camera thinks there isn't enough light. How do I force it to open the shutter?
The red box means the camera cannot confirm focus. In modes AF-S and AF-A the shutter will not release unless the camera believes it is in focus.
Use focus lock (focus/recompose), or another focus mode. AF-F, AF-C, and Manual allow shutter release without focus confirmation.
