Seagull Nebula Sadr Astro-2
The Seagull Nebula, 6 hours of integration in SHO with Red Cat 51 Petzval telescope, ASI6200mm pro 61-megapixel full-frame Mono camera, on Paramount MX 6 mount, are 74 shots of which in Ha 19x300 seconds, in OIII 20x300 seconds and in SII 35x300 seconds, processing with Pixinsight and Photoshop. All data and shots were acquired with Sadr Astro Observatory. The Seagull Nebula (also known as Gum 2, sometimes mistakenly known by the abbreviation IC 2177) is a diffuse nebula visible on the border between the constellations Canis Major and Monoceros.
The nebula is located about 9 degrees northeast of the star Sirius and extends for two degrees in the NNE-SSW direction, in an area very rich in hot and blue stars, of recent generation, part of the stellar association Canis Major OB1 to which the initials Canis Major R1 was initially assigned due to the presence of numerous reflection nebulae. It can also be identified with good binoculars, in which it appears, especially with averted vision, as a slight elongated halo; Its shape is clearly visible in large telescopes and suggests the shape of a seagull in flight, hence its proper name.
From an astronomical point of view, the object is a large H II region in which star formation is active, as evidenced by the presence of numerous infrared and X-ray sources associated with young or forming stars; in its surroundings you can observe a large number of other small nebulae, some of which are reflection, often recognizable by their bluish color. There are also some open clusters in the area, such as NGC 2353.
To the east of this nebulous complex is another, less extensive nebulous complex, known as LBN 1036; Both are part of the same molecular nebula complex, whose shape is due to the explosion of a supernova that occurred about 500,000 years ago. The extension of the complex is about 100 parsecs.
