The region Lac OB1 association includes some clouds lit with no visible emissions in the band of CO, masses of ionized gas and bright, and some small reflection nebulae associated with some massive stars. Nevertheless, the presence of clouds appears very reduced view of the association with massive stars, unlike other similar regions, in which to the left to young massive stars are found large quantities of gas. The region is home to only two clouds, showing signs of recent star formation activity: the westernmost, located near the most massive star of the association, is listed as LBN 437, while the second, located a bit ‘on the sidelines in the northeast, has a cometary appearance and is known by the acronym GAL 110-13. Both clouds are the residues of the great original molecular cloud from which the association was formed. The association is OB also divided into two subgroups, indicated by the letters OB1a Lac and Lac OB1b, divided by the proper motion and radial speed of their components.

LBN 437 nebula is the most central of the region; is located on the southeastern edge of a long cloud with CO emissions, which extends to the northwest and known as Kh 149, and a short distance from the nebula Sh2-126; the latter, also known as LBN 428, receives the radiation of the star 10 Lacertae, that ionizes making it luminous. The densest part of LBN 437, indicated with the letter A, is associated with some young stars and bright, among which stands LkHα 233, also known by the acronym distella variable V375 Lacertae.
