Description

Popularly known as the Seagull Nebula, the bird consists of a number of fabulous individually named objects spanning some 200 light-years in their entirety, which perfectly fits my equipment's FOV..  Unfortunately, from my location the bird flies at a maximum 28 degrees or less above the southern horizon (-11 DEC) and, furthermore, spends much of its time behind houses, trees, and tall hedges, thus providing just two short windows for imaging; combined with this winter’s terrible weather made it a tough target. However, despite the difficulties posed by the low transit of the Seagull in the night sky, each of the Ha, OIII and SII wavelengths are strong, making for good data acquisition and a very pleasing final SHO image.

Imaged over 4-nights between 18th January & 12th February 2024.
