Description

A famous region towards the heart of the galaxy, captured in wide field (about 3.5 x 2.3 degrees). The Lagoon Nebula (M8 or NGC 6523) is a vast cloud of interstellar gas in the constellation Sagittarius (55 x 20 light years across). To the lower right is the Trifid Nebula (M20 or NGC 6541), another colourful HII region. They are located 4,100 to 5,200 light years from Earth.

This astro-image was captured in urban (Bortle 6 skies), and created as a layered blend of 25 x 5 min and 55 x 30 sec subs, for a total integration of 2.5 hours.

Captured and pre-processed with flats (light box), bad pixel map and bias in Nebulosity. Post-processed in StarTools.
