Gecko Nebula in Lacerta (LBN-437)

www.astrobin.com/x59nmd/

 

The Gecko Nebula, also known as LBN 437, resides within the Lacerta constellation and is juxtaposed with the expansive emission nebula Sh2-126, which intersects it.

 

On this picture, the right lobe of the Gecko Nebula boasts numerous recently formed bright stars emerging from its molecular cloud.

Within this domain, the youthful star V375 is linked to the Herbig-Haro object HH398.

These phenomena represent luminous areas of nebulosity associated with nascent stars, originating from the collision between the star's ejected gas and nearby clouds of gas and dust.

 

Typically, images of this nebula are displayed with a 180º rotation, but I prefer this orientation to showcase it's intricate details in a highly magnified close-up view.

 

It's a result of 28 hours of integration time at f/3.3 (8 hours on LRGB + 20 hours on Ha).
