Image-field position and adopted distance
Butterfly Nebula (NGC 6302) image-field center is placed at J2000 RA 17.2 h, Dec -37.1° in Scorpius, at an adopted distance of 3,800 light-years.
Also known as Butterfly Nebula, Bug Nebula, NGC 6302, Caldwell 69.
One record per aspect. The origin says what kind of thing each value is; the source says where it came from; the limit says what it cannot tell you.

Butterfly Nebula (NGC 6302) (bipolar planetary nebula; central source NGC 6302 central star, dust-obscured stellar remnant): projected footprint at the adopted distance 2.6 × 3 light-years; outer radius used for arrival 1.5 light-years.
The light field samples the published telescope composite at its angular scale and adopted distance. Color follows the source’s assigned wavelength palette. Shallow depth is illustrative, not measured tomography; foreground stars and telescope diffraction remain features of the source image.
