So I decided to take a second look at the Seagull Nebula (IC 2177) from a wider field of view. Admittedly, I was shocked to see all of the rich nebulosity that surrounds this target. I was even more intrigued to see the close proximity of Thor’s Helmet (NGC 2359) to the Seagull Nebula; but that will be a subject for another capture 😊. The area is like a sea of hydrogen alpha (Ha) emissions, which is identified by the red in the photo. To give a clearer perspective, see the image below which is the Ha channel that was extracted from the dual narrowband filter used to capture the image. It is safe to say that Ha takes up most of the region.
Putting all of the technical details behind, this is undoubtedly a beautiful region in the night sky, with the seagull gliding in its full splendor, and apparently leaving a blue egg or defecate in its wake 🤭🤷🏾♂️. Whatever it may be, it is still a great reason to look up and experience an amazing Universe!!!
