SH2-126 and LBN 437 (The Gecko Nebula) in HaLRGB - 2 Pane mosaic

[emyliano2000]

I haven't done a mosaic in quite a while, this is only a 2 pane one to warm up a bit

This is my version of SH2-126 and LBN 437 (The Gecko Nebula) in HaLRGB - 2 Pane mosaic

SH2-126 is a large emission nebula in the Lacerta (The Lizard) constellation and it apears in this image as the red nebula. The source of its ionisation is the intense ultraviolet radiation from the star 10 Lacertae, a blue main sequence star.

The yellow-brownish nebula, which forms a "stellar funnel" in the centre-top of the image and snakes away to the right, is designated LBN 437 also known as The Gecko Nebula. 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.

This region, with its faint nebular filaments, is part of Lacerta OB1, a giant star-forming region about 1200 light-years from Earth.

The nebula emits its light in broadband and in isolated emission lines.
