OBJECT DESCRIPTION AND IMAGE SESSION

The Eta Carinae Nebula is one of the largest region of ionized hydrogen gas in our Galaxy. Expanded in a distance of 260 light years it has seven times the size of the Orion Nebula. The photograph only shows a partial view of the complex. The Nebula has produced the Star Eta Carina which is among of the most massive and luminous star in our Milky Way. NGC 3372 present us its generous detail and regions formed of bright and dark interstellar matter. The Eta Carinae Nebula was discovered by Abble Lacaille during his 2-year journey to the Cape of Good Hope in 1751/1752.

The image was taken in a dark site near the weekend house we rented in Tandil Buenos Aires close to the highlands. Unfortunately I placed the mount beside a big tree so a few minutes after starting the session, the leaves of an extended branch began to produce artefacts in the image. Fortunately this object is very generous and with just a few pictures it came out rather fine...a bit noisy though.
