Large, bright nebula with a complex structure, visible as a large glowing patch without the filter, with the OIII filter the structure becomes far more interesting, a circular structure dominates the north side, a hard brighter northern edge and a filament just inside this emphasize the spherical nature of the structure, a bright protrusion is on the south edge and continues west, there is extensive dimmer structure surrounding the sphere, particularly to the north and east, with Sam Rua's 25" even this extended area exhibits structure with a few knots and filaments, rich winter Milky Way starfield
