Fresh out of the oven.
My attempt at another region of the milky way after some encouraging results from M22 and M25 with only about 4mins of integration time. The Lagoon and Trifid Nebulae frames up very nicely with a 135mm focal length. I aimed for about an hour of integration time hoping to bring out the nebulosity of both nebulae. Hints of both nebulae can be seen on a single 15sec sub. I was lucky to complete imaging before moon rise.
The Lagoon Nebula (M8) is an emission nebula in the constellation Sagittarius. Located 5,200 light-years from Earth, M8 is home to its own star cluster: NGC 6530. The massive stars embedded within the nebula give off enormous amounts of ultraviolet radiation, ionizing the gas and causing it to shine.
The Trifid Nebula (M20) is also located in Sagittarius. Its name means 'divided into three lobes'. The object is an unusual combination of an open cluster of stars; an emission nebula (the lower, red portion), a reflection nebula (the upper, blue portion) and a dark nebula (the apparent 'gaps' within the emission nebula that cause the trifurcated appearance.
