NGC 7635, also known as the Bubble Nebula, is a stunning and prominent emission nebula located within the Milky Way galaxy. It is situated in the constellation Cassiopeia, specifically in the northern hemisphere of the night sky. The nebula is a captivating example of interstellar gas and dust being illuminated and shaped by the intense radiation of nearby massive stars.

The Bubble Nebula gets its name from the spherical or bubble-like structure that appears to encircle a massive, hot, and young star known as BD+60°2522. This star is responsible for ionizing the surrounding hydrogen gas, causing it to emit a reddish glow characteristic of emission nebulae. The bubble itself is formed by the intense stellar wind and radiation from BD+60°2522, which pushes the surrounding material outward, creating a shell-like structure.

The Bubble Nebula's intricate and colorful appearance is a result of the interplay between the ionized hydrogen gas, dust, and the light emitted by the embedded star. The hydrogen gas emits light in shades of red, while the surrounding dust scatters and reflects the star's light, producing a blue hue.

NGC 7635 is a popular target for amateur and professional astronomers alike due to its striking appearance and fascinating astrophysical processes. Observing this nebula requires a telescope equipped with narrowband filters to enhance the contrast of the emission lines and reveal the intricate details of the structure. It serves as a reminder of the dynamic and complex nature of the universe, where massive stars sculpt and shape the surrounding interstellar medium, creating breathtaking sights like the Bubble Nebula.

Within this image you can also see three other nebulas. The Lobster Claw SH 2-157, NGC7538, and another one (center) I can't identify.  

Here are the main features and characteristics of the Lobster Claw Nebula: SH 2-157

• The Lobster Claw Nebula's name comes from its distinctive shape, which somewhat resembles the claws of a lobster. The nebula features elongated and curved structures that give it a unique and intricate appearance. These structures are likely shaped by the interactions between the massive stars and the surrounding gas and dust.
• Distance:** The exact distance to the Lobster Claw Nebula is not precisely known but is estimated to be around 6,000 to 10,000 light-years away from Earth.
• Observations:** The Lobster Claw Nebula is a popular target for astrophotographers and amateur astronomers due to its striking appearance and intricate details. It often appears in Astro images and showcases the beauty of the interplay between massive stars and the surrounding interstellar medium.

Here are some key features and characteristics of the NGC 7538 HII region:

• Star Formation:** NGC 7538 is a hotbed of star formation. Within the dense molecular clouds of this region, new stars are actively being born. These stars are often massive and emit large amounts of ultraviolet radiation that ionizes the surrounding hydrogen gas.
• Emission Nebula:** The ionization of hydrogen in NGC 7538 causes the gas to emit light at specific wavelengths. This emission produces the colorful glow that is characteristic of HII regions. The most prominent emission lines are in the red portion of the electromagnetic spectrum, giving the region a reddish or pinkish appearance.
• Distance:** NGC 7538 is estimated to be around 9,100 light-years away from Earth, making it relatively close on the galactic scale.

If it be God's will we may be visiting this region again in the future for a little closer look of each nebula/region.  

This photo of the Bubble Nebula NGC7665 and the others in the area, represents four nights of collecting protons. Accumulating 72 five-minute exposures for a total of 6 hours of integration. This was one of my first nebulas to photograph. Primary focus was on the Bubble Nebula, however the Lobster Claw and NGC 7358 Hii made themselves available. It’s a three for one image with some noticeable color difference for the dust cloud in the area of these nebulas. I pray I will get opportunity in the future to photography it with a more powerful lens to zoom in on each. Something to look forward to for those who subscribe to this website. Astronomy photography requires specialized equipment, more work, more editing, and a lot of patience. Where God guides, he provides.
