Capturing Cosmic Wonders: The Lobster Claw & Bubble Nebulae 🦞🫧
Last night's clear skies offered a perfect opportunity for a deep dive into one of Cassiopeia's most dramatic celestial regions, revealing the breathtaking Lobster Claw Nebula (Sh2-157) and the iconic Bubble Nebula (NGC 7635).
This was my first time capturing this particular region, and while it's a starting point that definitely warrants more integration time, I'm thrilled with the results achieved so far.
The Science Behind the Beauty
These nebulae are vast clouds of gas and dust, illuminated and sculpted by the intense radiation and stellar winds from nearby massive stars. The Lobster Claw Nebula, a region of active star formation, displays intricate tendrils of glowing hydrogen gas. Adjacent to it, the Bubble Nebula is a spectacular example of a planetary nebula, formed by the expulsion of outer layers from a dying star, creating a beautiful, iridescent shell.
