I have a problem. And I would like your advice. I want to take a wide photo of the night sky. For this,I have a Nikon Coolpix P1000 bridge camera and a good tripod. The first problem with my camera is that it has a very small sensor (1/2.3"). It has an automated program for this kind of photography. But at my first attempt has shown star trails witch I don't desire. I can't easily find a dark place in my city,so I went to the terrace. I went to 24mm focal length and f2.8 on manual mode. At the manual focus with light pollution around me I took a wild guess and simply aimed at the infinity. The thing is that, when I choose ISO1600,in manual mode, the camera does not allow me to go to apperture speed slower than 1"!! If I want to go further to thirty seconds I have to go to ISO100!!! On the other hand, the automated scene goes to 25secs! Should I even bother to try to shoot 20-25 seconds with ISO100,is there any other way to surpass this limitation,or should I stick to the preset scene?
