ILLUSTRATION FROM REFLECTION NEBULA · MAJOR AXIS 5′
OVERVIEW
] NEBULAToby Jug Nebula is a reflection nebula in the constellation Carina. It is catalogued as ESO 124-003, ESO 124-3 and HD 65750, among 7 designations in total. It was discovered in 1900.

- 5.0
Small enough that the full Moon would cover it several times over.

THROUGH AN EYEPIECE
] 150 MM TELESCOPE · 25 MM EYEPIECEToby Jug Nebula covers 5.0′ of sky against a of 1.08°, so at 48× it is a small patch, centred.

Toby Jug Nebula is not a point of light, so the limit above is the wrong one to hold it against: the same brightness spread over 5.0′ 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 J2026.7Where 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.

- GRID TURNED SINCE
- 5.7
- PROPER MOTION SINCE
- none published
Computed for 2026-08-28 00:00 UT. No proper motion is published for Toby Jug 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.

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.
