Image Description and Details : Data reprocessed under cloudy skies in March '22

LBN 437 is a molecular cloud in the constellation Lacerta. It is located at the edge of the much larger emission nebula Sh2-126 and the star forming region Lacerta OB1. The densest part of LBN 437 (centre) is associated with some bright young stars, among which the variable star V375 Lacertae, which is an Herbig object, with strong Hα-emission. This star is also responsible for the excitation of some bipolar Herbig-Haro-Objects situated in the nebula (HH 808, HH 809, HH 398).

Image Description and Details : Sharpless 126 (Sh2-126) is the designation of a large emission nebula in Lacerta, which appears in this image as a red background and exceeds the edges of the image. The source of its ionization is the intense ultraviolet radiation from the star 10 Lacertae, a blue main sequence star.

The nebula, which forms a "stellar funnel" in the center of the image and snakes away to the right, is designated LBN 437. It is a molecular cloud whose densest part is associated with some bright young stars. Its most striking feature is a symmetrical reflection nebula associated with the Herbig Ae / Be star V375 Lacertae. This star is also responsible for the bipolar Herbig-Haro objects within the nebula. Herbig-Haro objects are small nebulae around young stars. They form when gas ejected by the star hits dust clouds.
