"This was taken from the Albert L. Ruppel Observatory—my backyard observatory," says Ruppel. "Much of the data collected for this image was obtained through a Hydrogen alpha filter. Emission nebulae, such as IC 5068, shine in hydrogen alpha light at a very narrow wavelength. Fortunately, the filter which passes this wavelength blocks most other light sources and permits deep sky imaging even from locations with severe light pollution. This allows me to image these majestic gas clouds even though I live in the suburb of a large city."
