Brightness: 2           Alt: 50°
Description: One obvious cluster., visible even in a 6x30
finder. The brightest stars (7-8m) a in two lines. Together
these two lines outline a L. About 30 stars of mixed magnitudes.

Megastar shows 3 cluster labels in this area: 

NGC 1746 centered in the western parts of the obvious cluster.
Size given as 41', class III 2 p and #stars 20. The SAC database
lists it as mag. 6.1 and gives a descr: "Cl,Poor" I think this
is the bright and large cluster which is clearly seen in the
drawing. 

NGC 1750 is labelled (at the position marked with a "x" in the
drawing) in Megastar, but no other data is diven. SAC: "Cl,st L,
vc sc" "Part of -46" This is probably the clump of bright stars
visible in the drawing a bit W of the given position. 

NGC 1758 is centered in the eastern parts of the big cluster in
Megastar. Size is given as 40', Tr type III 2 p and #stars 20
which is exactly the same data as for -46! But there is a clear
cluster of fainter stars (10,12...) very near the position. Diam
10'. The place of this group is shown as a circle in the
drawing. SAC: IV 1 p, "Cl, pC, st L & S" I think this fainter
group fits the NGC description better than the large group. 

Summary: 
NGC 1746: The large cluster.
NGC 1750: A clump of stars in -46.
NGC 1758: A smaller cl. in the eastern parts of -46. Prob. not
          real.
