IC 590
ILLUSTRATION FROM HUBBLE TYPE -5 · MAJOR AXIS 0.9′ · POSITION ANGLE 105°
OBSERVING
] FROM WHERE YOU AREWhat it takes to see IC 590 for yourself. Everything in this part of the page is worked out for a real horizon, a real night and the equipment you say you have.
Say where you are, and this line says when IC 590 is worth going out for.
THROUGH AN EYEPIECE
] 150 MM TELESCOPE · 25 MM EYEPIECEIC 590 covers 54″ of sky against a of 1.08°, so at 48× it is a speck in a wide field.

IC 590 is not a point of light, so the limit above is the wrong one to hold it against: the same brightness spread over 54″ 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.

- DECLINATION
- GRID TURNED SINCE
- 22.1
- PROPER MOTION SINCE
- none published
Computed for 2026-08-28 00:00 UT. No proper motion is published for IC 590, 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
] 7 FIELDSThe 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.
WHAT KIND OF THING IT IS
What the object is in itself, rather than how it happens to look from here.
- Hubble type
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.
