This deep space nebula really lives up to it’s name in this colour treatment, and looks like an overflowing reservoir of space water. I’m hoping to get some truecolour over the next little while on this incredible region, but am still amazed at the detail and clarity of the filtered light in the photo. The dominant colours here are hydrogen and sulphur emissions from the Messier 8 region, commonly known as the Lagoon Nebula but the area besides is NGC 6559 and Simeis 188 which are great to frame altogether with this kind of wider field of view. This deep exposure is possible fairly quickly with the Celestron RASA 8 and was taken while the full moon was above the horizon!

Shared here as public domain 4K downloadable wallpaper because ultimately I’m a professional computer desktop wallpaper photographer and this suits my big new screen quite nicely! Worth downloading and exploring at 100% – Direct download >
