Our First Images of a "Bubble-Like" Object Near The Crescent Nebula in Cygnus
As previously noted, PN G75.5+1.7, also known as the Soap Bubble Nebula, was "discovered and reported" by Dave Jurasevitch on July 6, 2008 and, per the IAU (International Astronomy Union), was "independently noted and reported" by Mel Helm and Keith B Quattrocchi on July 17, 2008.
The Soap Bubble Nebula is an unusually symmetrical planetary nebula (a small dying star which ejected its atmosphere and became a white dwarf). It is difficult to visualize, being hidden in a sea of hydrogen near the Crescent Nebula.”

The first image (Figure 1) is the original image obtained by Dr. Helm at Sierra Remote Observatories, with the suspected "Bubble-Like" Nebula in the lower left corner. The image which follows (figure 2) is the confirmatory image by Dr. Quattrocchi.
