In December we shall be heading out to Finnish Lapland to have xmas dinner with Santa and hopefully catch a display of the Northern Lights. I am not particularly familiar with cameras, just have a normal low end digital camera for everyday sort of general shots. Now I appreciate that this will not be suitable but really have little idea as to what I should be looking at, I gather low ISO for long exposure shots is one of the features I should look for. Therefore could anyone advise on cameras (by budget would be approx £300 top) or camera shops where I would gain some decent advice without being fleece into buying something unsuitable for too much money. Thanks
