Description

NGC 7635, also known as the Bubble Nebula, is a nebula approximately 10 light years in diameter located in the constellation Cassiopeia.
It is formed by the stellar wind created by the star SAO 20575 at a speed of over 1,700 km / s. This star, eccentric with respect to the cloud, is the brightest. It is very young (less than 4 million years old), very hot (about 35,000 degrees) and massive (20 to 40 times the solar mass). The star is not in the center because the expanding cloud meets a denser, cooler region on one side. It should explode into a supernova in 10 to 20 million years.
Image taken from August 10 to 14 over 2 nights, 10 hours of exposures kept.
C9 Edge + reducer, 60d astrodon cannon, Altaïr Quadband filter.
