LBN 438 - A Dune Worm
LBN 438 is a dusty nebula located in the constellation Lacerta, known as the sandworm or shark nebula. It is a really faint nebula, it is illuminated by a type of interstellar radiation known as Extended Red Emission (ERE). ERE is a relatively recent discovery, at the end of the 20th century, it is a photoluminescence process by which hydrogenated amorphous carbon (Carbon without crystalline structure) is illuminated by interstellar photons. The nebula also contains ionized hydrogen, but emits a relatively weak Ha signal, so I decided to use broadband and Ha filters to capture this object, trying to go very deep in Ha, this image contains about 23h of Ha.
At the top of the nebula there is a reddish glow, which I assume is due to ERE, since the glow is brighter than the rest of the Ha present in the image. If you look closely at the background of the image you will be able to see several small galaxies.
I hope you like it.
