OBJECT DESCRIPTION AND IMAGE SESSION

One of the brightest HII regions of our Galaxy located in the constellation of Carina. These two regions seems to be associated however there are just companions in perspective, since they are separated by at least 13.000 light years. NGC 3603 which appears smaller in the  image is in fact larger covering 1000 light years; while NGC 3576 is smaller with only 100 light years wide although in the image seems to be larger. Bok Globules are also visible in NGC 3576 curved arms.

 

The session was interrupted with clouds so the exposure time last less than an hour. No matter that we spend a very nice time with my friend Guillermo down in the Mountains.
