OBJECT DESCRIPTION AND IMAGE SESSION
The Carina Nebula
(catalogued as NGC 3372; also known as the Great Carina Nebula is a large,
complex area of bright and dark nebulosity in the constellation Carina,
located in the Carina–Sagittarius Arm of the Milky Way galaxy. The nebula is
approximately 8,500 light-years (2,600 pc) from Earth.
The nebula has within its boundaries the large Carina OB1 association and
several related open clusters, including numerous O-type stars and several
Wolf–Rayet stars. The nebula is one of the largest diffuse nebulae in
our skies. Although it is four times as large as and even brighter than the
famous Orion Nebula, the Carina Nebula is much less well known due to its
location in the southern sky. It was discovered by Nicolas-Louis de Lacaille
in 1752 from the Cape of Good Hope.
I have started imaging this object just passing the meridian and falling to the west which is in fact the darkest area of the Observatorio Cielos Albertinos.
Great night with good company... meeting astrophotographers and local authorities of Alberti
By the 2023 summer Buenos Aires interior is suffering from the "la niña effect" and consequently we had dry fields over the pampas. North winds brought some dust into de atmosphere which was of very little effect on a 200 mm focal length lens.
