I also have a point and shoot camera that we bought especially for our trip in September-October, and I am really worried that I am going to get it all wrong and the shots of spectro and fireworks will be really poor. Just like the above poster, I would welcome and appreciate any and all help you might be able to give. I don't trust the 'heart' setting on this thing but I do usually use auto mode for things and they come out very well, just highly doubt this will apply to night shots. I have a Canon Powershot SX120 IS -
