41 Eri is a star rich in mercury and manganese and is a spectroscopic binary (both
stars are equals) with an orbital period of only 5.0105 days. It is a member of the
Pleiades Group, a large family of stars with a common origin and similar motion through
space.
Observations:
C8 at 104x. A diffraction mask helps. Rich field.

NGC 1532
Other Names: PGC 14638
Rating: 5 D
Position: 0412-3252
Type: Gal
Surface brightness: 13.6
Class: SB(s)b pec
Dimensions: 5' x 1'
Magnitude: 11.8
PA: 33
Notes:
The unusual plumes in NGC 1532 suggest a tidal distortion due to an encounter. The
evident candidate responsible for the perturbation is the amorphous companion NGC
1531, whose morphology is of the same class as M82. The two galaxies form a physical
pair.
[Source: http://nedwww.ipac.caltech.edu/cgi-bin/nph-datasearch?search_type=Note_id&objid=10547&
objname=NGC%201532]
This galaxy produced SN 1981A.
Observations:
C8 at 104x. It is very faint and difficult, due in part to its low latitude and my awful
Kansas City sky glow to the south.
