The Bubble Nebula Region of the Milky Way Galaxy

The Bubble Nebula appears at the very centre of the wide-field image below. It is actually a shock wave of gas and dust pushed outward by a powerful star 45X the size of our sun at the centre.

Surrounding the Bubble Nebula are pink molecular clouds of hydrogen, but oxygen also appears as blue, with nitrogen as green, resulting in an unusual teal coloured background.

At a distance of only 7,000 light-years, consider it nearby on a galactic scale of 100,000 light-years. This tiny bubble is a mere 6 light-years across. However, this is 1000X larger than the 2 light-DAYS span of our tiny solar system (6x365/2 = 1095 times larger than our solar system)

This is a faint object for a backyard telescope, and requires 5 minute exposures. I took 144 images (12 hours of photography). I photographed the Bubble Nebula Region from my garden in Strasbourg France over three nights in August 2025.

The Bubble Nebula - NGC 7635 I've been shooting this target for a while now in a widefield format -> 480mm, 380mm, and 275mm. Now I've shot it at around 1400mm. I finally got another filter drawer and I decided to test out how long I could shoot using just a guidescope and the longest comfortable time was around 180s. I plan on returning the Canon to the Raptor but I'm glad I was able to get the EdgeHD 8 figured out for the most part. .

Bubble nebula by Guillaume Seigneuret Via Flickr: NGC 7635, also called the Bubble Nebula, Sharpless 162, or Caldwell 11, is a H II region emission nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star, SAO 20575 (BD+60°2522). The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow. It was discovered in 1787 by William Herschel. Picture done at Rians in France Camera : QHY163M cooled (-20°c) Scope : Newton 150mm f/4 Mount : Avalon Linear Guiding : QHY5LII + Canon 200mm F/4 L IS Color : HOO 3 hours Exposure with : Ha 7nm : 30x180" OIII 8.5 nm : 30x180" 20 Dark no Bias Due to bad collimation of the newton, stars are not perfectly round :/

NGC 7635: Bubble in a Cosmic Sea Image Credit & Copyright: Sébastien Gozé

Explanation: Do you see the bubble in the center? Seemingly adrift in a cosmic sea of stars and glowing gas, the delicate, floating apparition in 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. Also included in the breathtaking vista is open star cluster M52 (upper left), some 5,000 light-years away. The featured image spans about two degrees on the sky corresponding to a width of about 375 light-years at the estimated distance of the Bubble Nebula.
