Description:
NGC 1532: 9,8mag, 12,6x3'. Very bright beautiful edge-on that streches over 
approx 8x2'. The core is bright and oval. With averted vision I could see a 
bright elongated cloud (size ~1,5x0,5') close to the SW-end of the galaxy. Dark 
lane suspected (?).

1532's neighbor NGC 1531: 12,5mag, 1,3x0,7'. Located in an angle of 90° to 
1532. It is only 2' away from the bright NGC 1532. 1531 is oval and extends approx 1,5x0,7'. Apart from the two bright NGC galaxies there is a few fainter 
ones attached to the pair. 

IC 2040: 13,1mag, 1,4x0,8'. Located 20' NE of NGC 1532. It's faint but clearly 
visible at 131x as a 1x0,5' oval smudge with a slightly brighter center. 

IC 2041: 14mag, 1x0,5'. Much closer to the bright edge-on (7' ENE) but requires 
averted vision and high magnification (342x). I could not see IC 2041 using 
131x magnification. Another extremely faint member of the group - ESO359-29 - 
escaped my view as it was obviously too faint. The whole group is located at
-33° a few degrees E of the huge impressive Fornax I Cluster.
