M8 - Lagoon Nebula in Sagittarius
with 10" f/3.9 Astrograph
Uploaded 6/7/26

 
One
            of the brightest and most spectacular hydrogen nebula in the
            summer sky is M8, the "Lagoon Nebula". Found in the
            constellation of Sagittarius, we have a star cluster in the middle
            illuminating the huge cloud of glowing hydrogen gas. You can
            see pinks, red, and magenta in this object which is hundreds
            of light years across. Taken with our 10 inch telescope here
            in Payson.
