The Lagoon Nebula (M8) in Sagittarius

The Lagoon Nebula is a magnificent object, which can easily be seen by the naked eye as a moderately-sized hazy patch.

M8 is a bright and very large emission nebula with an embedded open cluster. The young stars in this cluster are heating the gas in the nebula, which then causes it to emit light.

In binoculars, the dark lane (the lagoon) that splits the nebula's brighter parts (and hence, gives the object its name) becomes apparent. A telescope starts to reveal the nebula's intricate folds and darker regions amidst brighter regions.

Dark "Bok globules" in the nebula mark areas of dense gas clouds and dust which are where new stars are being formed.

North is left.

This composite consists of one set of images; one set of 34 images taken at ISO-400.
Each individual image was a 240 second exposure.
IRIS was used to calibrate each image (dark subtraction [median combined master dark] and flat field division [median combined master flat {lights and darks}]), to register, align, and finally stack.
Photoshop CS2 was used to adjust levels, curves, frame and resize the final composite.

Avrei voluto essere sole
Per riscaldarti e asciugare i tuoi capelli.
Avrei voluto essere nuvola soffice e pura
Per avvolgerti e proteggerti da ogni cosa.

E così…senza dire una parola
Ti ho stretto tra le mie braccia.

This is fantastic. Last year I spent a lot of time looking at some very dull pics, and this year I'll be trying to work out a way of going through terabytes of data on the stars, making it easy to forget that sometimes they just look great!

minion-for-hire,

Thank you for the compliment.

I can only imagine the number-crunching-type work that you must do. Sometimes it's nice to take a step back and look at the big picture, as you've pretty much stated. :)

Regards,
H

Managed to have a bit of fun at a recent meeting with another research group: they run a youth outreach centre for late primary/early secondary school children, and we got to play with it for a bit at the meeting cause the place was deserted in the run-up to Christmas. It was interesting to see a group of University researchers playing children's games. :)

I really like this one <3 Just by seeing the fluid look of it you can understand how it got it's name.
There are very few shots like this these days. Thanks for the picture
