Previously, the object was classified as an open cluster; however, it was shown through more recent observations that it is a random formation of stars in Earth's sky, an asterism.

NGC 1746 is a sparse, large star grouping that spans around 40 arcminutes.

Originally classified as an open cluster, later studies suggest it is likely to be an asterism.

NGC 1750 is a true open star cluster, spanning 20 arcminutes, with an estimated age of 150–200 million years.

NGC 1758 is a smaller and denser open cluster, about 10 arcminutes in size.
