It's mainly getting enough light that you can see the crane rather than just a glow of light, but without it being blurry or grainy. I vaguely remember ISO and stuff like that from my photography course, which is helping a little, but I'm sure the pictures could be better. This is why I discounted photography as a Light Night proposal!
And just to prove my non-photographer credentials, here's my "studio" - my wardrobe. See the clothes horse/air dryer thing? That's what I rest the camera on to keep it steady.
So can anyone suggest hints and tips, that don't involve shelling out thousands on new cameras and such?
