Last weekend I did magic with my camera. In a single one minute image, I could only see stars. No signs of nebulosity at all, even zoomed in and brightened on my laptop. But when I stacked 334 images together (5 hours and 34 minutes, taken over two nights), viola! IC434 the Horsehead Nebula and NGC2024 the Flame Nebula were both visible. How cool is that?
