While searching the photo plates of the «Palomar Observatory Sky Survey» made with the 48 inch Schmidt telescope, the American astronomer Stewart Sharpless came across the emission nebula Sh 2-242 and published it in 1959 together with a total of 313 H-II Regions in a catalog. [310] In 1965 Beverly T. Lynds published her «Catalogue of Bright Nebulae» that she found on photo plates of the same sky survey. She listed there Sh 2-242 as LBN 182.30+00.07 (LBN 826). [270]
