OVERVIEW
] GALAXYSculptor Filament is an intermediate spiral galaxy SABc in the constellation Sculptor, shining at apparent magnitude 11.11 (). It is catalogued as 2MASX J00473313-2517196, C 65 and Silver Coin, among 14 designations in total. It was discovered in 1783.
The brightest galaxy in the Sculptor Group, dusty and bursting with star formation, and one of the easiest galaxies to see from the southern hemisphere.

OBSERVING
] FROM WHERE YOU AREWhat it takes to see Sculptor Filament 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 Sculptor Filament is worth going out for.
THROUGH AN EYEPIECE
] 150 MM TELESCOPE · 25 MM EYEPIECEOut of reach of binoculars; a 150 mm telescope reaches it. Sculptor Filament covers 26.8′ of sky against a of 1.08°, so at 48× it is comfortably framed.

Sculptor Filament is not a point of light, so the limit above is the wrong one to hold it against: the same brightness spread over 26.8′ of sky is harder than a star of it, and goes first — spread out, it comes to 22.4 . 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.
- RIGHT ASCENSION
- DECLINATION
- GRID TURNED SINCE
- 20.0
- PROPER MOTION SINCE
- none published
Computed for 2026-08-27 00:00 UT. No proper motion is published for Sculptor Filament, 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.

What the object is in itself, rather than how it happens to look from here.
- 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.
