Over 5-hours of data with the Sky 90 at f#4.5 at the top and exactly 5-hours of data with the C11 at f#2 (Hyperstar III) on the bottom. Note how much of the faint outer arms has been captured by the shorter Hyperstar III data as well as the large number of faint stars that are actually missing from the Sky 90 image. Processing by Noel Carboni.
