Description

This bright emission nebula in Sagittarius is not far from the famous Eagle nebula (M16), and lies about 5000 light years away.

The central core is very bright, and appears white in visible light ... a mixture of light emissions from the hottest gasses, and reflections of nearby bright stars on the dust in the region.

This image has natural star colours (captured without any filters), and narrowband data for the nebulosity.
(H)ydrogen emissions are mapped to Red
(S)ulpher emissions are mapped to Green
(O)xygen emissions are mapped to Blue

At over 20 hours in total, it's my longest integration yet :-)
