The bat-shaped molecular condensation appears to be an evolutionary gradient along the isolated filament in which LDN43 is embedded, itself part of the Sco OB2 complex (group of young, hot, and massive stars of class O and B, the brightest in the sky).
The Sco OB2 complex is a large star-forming region centered in the constellation Scorpius. It is the closest cloud to us and it is one of the most spectacular and photographed areas of the entire Milky Way. It is full of molecular clouds and dust. young and massive star clusters, emission, and reflection nebulae.
This is the first part of our 5th ShaRA project.
For the processing, we opted for a classic LRGB session with 300s exposures in bin1, taking advantage of the half-meter f/3.8 Newtonian (the T3) and sharing the rental costs with 17 different people.
This is the result of our ShaRA superstack! More info here:
