Sometimes, I'm outside at night still having a camera on me and see something nice I then try to photograph without a tripod. Works fine as long as you can put the camera on the ground, but trying to hold the shutter for a minute with your hand didn't work out that well.
The moon I actually took standing with quite a high shutter speed. It looks blurry though, because I had to crop a lot to get it that big. The second picture is Hamburg a few nights ago, where I just laid the camera on the ground to make a long exposure. Third one I made yesterday night at a friends birthday outside the city, where I was reminded of how many stars you can see without all the lights in the city.
It didn't turn out as I hoped, because I had to hold the shutter whilst an exposure time of over a minute.
Hopefully, I'll soon get another chance of taking pictures of stars outside the city.
