These two objects are apparently the same size the the sky, but they are not the same at all. The object on the upper right (M97 - The Owl Nebula) is a star that is expelling gas shells at it slowly dies and becomes a white dwarf. It is only approximately 1500 light years distant from Earth. The object in the lower left of the frame is a nearly edge-on galaxy (M108) that is composed of several hundred billion stars and is approximately 45 million light years distant from Earth. These two objects can be captured in a single frame and make this area of Ursa Major a very nice place to point your telescope! This image is a combination of narrowband data taken with an SBIG ST2000XM camera through Optec Ha and O3 filters, and some earlier data taken with an FLI CM-10 camera. The CM-10 camera has a chip that "blooms', which means that the brighter stars essentially "drip" data across the CCD. These brighter stars were corrected for using software. This image includes over 7 hours of luminance, red, green, blue, hydrogen alpha, and O3 data.
