PGC 130608
ILLUSTRATION FROM HUBBLE TYPE E · MAJOR AXIS 0.516′ · AXIS RATIO 0.49 · POSITION ANGLE 54°
OVERVIEW
] GALAXYPGC 130608 is an elliptical galaxy E in the constellation Indus, 247.4 from Earth, shining at apparent magnitude 16.20 (). Other catalogues list it as WISExSCOS J210608.84-470905.5.
- WHAT IT IS
- Elliptical galaxy
- HOW FAR
- 247.4
- HOW BIG ON THE SKY
- 31
- HOW BRIGHT (B)
A luminosity distance, from its redshift — how faint it looks. The light itself left 228 million years ago.
Small enough that the full Moon would cover it several times over.
Faint: it takes a large telescope.
THE MODEL
] LIGHT ALONG THE RAYCALCULATED · NOT AN OBSERVATION · ANGULAR SIZE AT THE CATALOGUED DISTANCE · HUBBLE TYPE E · MAJOR AXIS 0.516′ · AXIS RATIO 0.49 · POSITION ANGLE 54° · NO SURFACE — DRAWN AS A VOLUME · AXIS RATIO READ AS ITS OWN SHAPE
A spheroid whose brightness falls off as the quarter power of the radius, which is the profile de Vaucouleurs measured for elliptical galaxies and the profile the bulge of every spiral has. The shape of it is the catalogued class; the flattening is the catalogued axis ratio read as the object's own shape rather than as a tilt, because this is not a disc and its ellipticity is not an inclination. Nothing measured the depth, so what is drawn is the roundest object that matches the ellipse the catalogue holds. The two colours are two populations: old stars in the bulge and the disc, young ones in the arms, both through the same blackbody table as the star pages. Drag it, or use the arrow keys, to look from another direction. The stars behind are the 498,631 this catalogue holds real distances for, drawn from where the camera actually is — but every one of them is within 170 parsecs of the Sun and this object is much further out, so from here that whole neighbourhood is a knot in one direction and the rest of the sky is empty. The view you land on looks the other way; turn back towards the Sun and the stars come with it. What the readout says is which of the two the frame is pointed at. The emptiness is not a missing backdrop — it is the edge of what this catalogue has measured.

THROUGH AN EYEPIECE
] 150 MM TELESCOPE · 25 MM EYEPIECEFainter than the largest telescope modelled here reaches. PGC 130608 covers 31″ of sky against a of 1.08°, so at 48× it is a speck in a wide field.

PGC 130608 is not a point of light, so the limit above is the wrong one to hold it against: the same brightness spread over 31″ 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 J2026.8Where 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.
- RIGHT ASCENSION
- DECLINATION
- GRID TURNED SINCE
- 19.8
- PROPER MOTION SINCE
- none published
Computed for 2026-10-12 00:00 UT. No proper motion is published for PGC 130608, 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. The catalogue it came from publishes no error for that position, so nothing here says how far this arithmetic can be trusted — the digits above are as precise as the place they were computed from, and no more. Aberration, parallax and refraction are left out. Aberration swings every position by up to twenty arcseconds over a year; parallax stays under an arcsecond for all but the nearest stars; refraction is nothing overhead and about half a degree at the horizon, where it answers to the air, not the sky. The same figure for any date.

- Hubble type

HOW BRIGHT IT IS
What the light adds up to, measured through one filter at a time. A magnitude is a brightness on a backwards scale — the smaller the number, the brighter the object.

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.
