The Lagoon Nebula ... Messier 8



The Lagoon Nebula ... Messier 8

M8 is a giant spectacular emission nebula in Sagittarius and is located at a distance of somewhere between 4,500 to 6,000 light-years. Within this awesome nebula, new stars are being born. I took this 80 minute image Saturday night, July 27, beginning around 11:30 pm. (The stars in the upper right quadrant in the full picture are out of focus ... Seems to be an issue with the mirror alignment.). The AVX mount was at its maximum weight limit but tracking was spot on ... very small RMS error of 0.24px.

I took this 15 minute wide view of the Milky Way with my Canon T7i piggy-backed atop the telescope. Here you can see the 'Milkiness' of the core of our galaxy. Within this region lies several 'Messier Objects' including M 17, also known as the Omega Nebula. Jupiter was off to the right and as you can see, it moved a bit toward the east (left).
