Corwin's Notes

===== NGC 1750 may be the same object as NGC 1746 (which see). If so, there is a 10 arcminute error in the declination for N1746. The group of stars I see on the POSS1 close to WH's place consists of about 20 9th to 12th magnitude stars scattered over an area 25 arcmin by 12 arcmin, with the long axis at PA roughly = 125 degrees. I put the cluster center about 3 arcmin east of WH's RA. Reinmuth claims this to be the central group in a very large cluster also containing N1746 and N1758. Galadi-Enriquez et al (A&AS 131, 239, 1998) have confirmed the reality of this cluster as well as NGC 1758. They have also shown, however, that the clump of stars I call NGC 1746 (which see) near d'A's position is not a true cluster.

Steve's Notes

===== NGC 1750 17.5" (1/19/91): prominent subgroup of two dozen stars within NGC 1746 on the SW side. Fairly large, oval outline oriented NW-SE, void in the center. Includes a nice double star 9.1/9.1 at 20". NGC 1758 is close NE (though probably physically unrelated ). Modern catalogues apply NGC 1746 to the entire cluster (see description), although NGC 1750 (from William Herschel) and NGC 1746 (from d'Arrest) are either identical or just parts of the same cluster. 13": group of fainter stars, just SE of open cluster NGC 1746.
