"Seemingly adrift in a cosmic sea of stars and glowing gas, the delicate, floating apparition near the center (next to a blue
tinted star) of this widefield view is cataloged as NGC 7635 - The Bubble Nebula. A mere 10 light-years wide, the tiny
Bubble Nebula and the larger complex of interstellar gas and dust clouds are found about 11,000 light-years distant,
straddling the boundary between the parental constellations Cepheus and Cassiopeia."

For this image, I added an H-alpha channel for the first time to capture "red" detail otherwise invisable in an image. Total
exposure time was 125 minutes.
