NGC 7635

NGC 7635 is an emission nebula in the constellation Cassiopeia. It is nicknamed the "Bubble Nebula" due to its shape. It is located near the open star cluster Messier 52. The bubble was formed by the powerful stellar wind from a hot, massive star that is rapidly losing mass in the final stages of its life. When this supersonic stellar wind collides with the interstellar material of a nearby giant molecular cloud, it creates a shock front that shapes the bubble. Overall, testing the filter proved problematic. At the very least, there were issues with focusing on the object itself, which necessitated an additional trip for more imaging.
