OVERVIEW

] NEBULA

the Running Man Nebula is a nebula with cluster in the constellation Orion. It is catalogued as C 0532-048, MWSC 587 and NGC 1977. It was discovered in 1786.

FIELD 1.08°

the Running Man Nebula covers 10.2′ of sky against a of 1.08°, so at 48× it is comfortably framed.

the Running Man Nebula is not a point of light, so the limit above is the wrong one to hold it against: the same brightness spread over 10.2′ of sky is harder than a star of it, and goes first. Catalogued sizes are measured to a photographic contour, and the part an eye sees is usually smaller.

APPARENT PLACE

] EQUINOX J2026.7

Where a telescope has to be pointed today, which is not quite where the catalogue records the object: the coordinate grid itself has turned since the year 2000 the catalogue is referred to.

DECLINATION
GRID TURNED SINCE

PROPER MOTION SINCE
none published

Computed for 2026-08-28 00:00 UT. No proper motion is published for the Running Man Nebula, so nothing here moves the object; what separates this from the catalogued position above is the coordinate grid turning under it — about fifty arcseconds a year of precession since 2000, and the small nodding of the Earth’s axis on top of that. Aberration and refraction are not included, and neither is parallax; each is under an arcminute, which is also about as well as the catalogued position is known. The same figure for any date.

CATALOG DATA

] 4 FIELDS

The raw catalogue values, as the source published them, with the error bars where one was published — sorted by what each set of figures is about rather than by the order they happened to be stored in.

WHERE IT IS AND HOW IT MOVES

Position, motion across the sky and the size it covers on it. These are measurements of the object as seen from here, so every one of them depends on where here is.

Each link carries the identifier printed beside it. Nothing on this page is a measurement of our own, so a number that disagrees with one of these is worth reporting — and a service that has never catalogued this object under this name will say so plainly.
