There is a dark lane in the Milky Way that runs horizontally a little below the middle of the picture. If you look closely, you can see some red emission nebulae in the dark lane. I'm pleased that they are visible at all, because my stock camera is not sensitive to the almost infrared wavelength of these emissions. There is a thriving cottage industry that has grown up around modifying Canon cameras to make them more sensitive to the hydrogen-alpha emission wavelength.
