In 2000 Axel Mellinger published his famous panorama of the whole milkyway. Until today it is worldwide well known in the scientific community and also well known for its worth in public astronomical education. At that time he used chemical film and a lens of 28mm focal length to gain the 51 frames necessary for the panorama.
In 2009 Mellinger, by now Assistant Professor of Physics at Central Michigan University, repeated his project with modern CCD-equipment. He used an SBIG STL 11000 camera and Astronomik RGB-Filters Type 2c. He took each frame with a 50mm lens five times with each of the three filters and with three different exposure times (240s, 15s and 1/2s). In total he needed more then 3000 frames to produce his new panorama. By the use of his equipment and imaging technique he was able to create a final image in natural color with a considerably increased dynamic range.
