Space photographer Terry Hancock took the photo from Down Under Observatory in Fremont, Mich. after 11 hours of exposure time on the nights of Aug. 15, 16 and 18.
To capture the amazing nebula photos, Hancock used a QHY11 monochrome CCD camera, QHY Color Filter Wheel, Astronomy Technologies Astro-Tech 12" f/8 Ritchey-Chrétien astrographoptics, Paramount GT-1100S German Equatorial Mount (with MKS 4000), and image acquisition software Maxim DL5.
"While the skies were clear the seeing conditions were quite poor due to high humidity," Hancock wrote SPACE.com in an email.
Approximately 6 light-years wide, NGC 7635 is located roughly 7,100 light-years from Earth in the constellation Cassiopeia. A light-year is the distance light travels in one year, or about 6 trillion miles (10 trillion kilometers). Intense radiation and stellar winds from a nearby star created this delicate-looking bubble, which shines pink because of surrounding red, hot gas.
