“…In Drey er's New General Catalogue, published as Memoirs of the Royal Astronomical Society, XLIX, Part 1, NGC 1252 is listed as a probable cluster containing 18 or 20 stars. However, it is not included in Ruprecht Balázs, and White's (1981) Catalogue of Star Clusters and Associations. We have made a study of NGC 1252 because the semiregular variable carbon star TW Horologii (= HD 20234) is located in the cluster region.…”
