This disc will take you on an imaginative journey to a black hole. We cannot directly see a black hole itself due to its extreme gravity preventing light from escaping. This image is an interpretation based on the best data we have right now. The black hole's appearance is due to the limitations in current observation technology. This disc is permanently mounted into the new star disc tray which insures exact alignment offering incredable realisim. This star disc will NOT work with other brands of star projectors
