Background
M20 is the Trifid Nebula — a striking star-forming region 5,200 light-years away in Sagittarius, combining a bright pink emission nebula, a blue reflection component and three prominent dark dust lanes that divide the bright region into three lobes (giving the name).
My Observing Notes
25-cm (Meade 10-inch LX200, The Coffee Grinder): Although fainter than the nearby M8, gives lovely views — the bright mass of nebulosity bisected by the dark veins (the namesake) is clearly prominent.(Saturday, June 2025)
25-cm (Meade 10-inch LX200, The Coffee Grinder): Revisited with the 35 mm Panoptic. The dark veins bisecting the nebulosity are even more striking with the wider field.(Saturday, August 2025)
44-cm (Club 17.5-inch f/5): Returned to the Lagoon area through the Club's 17.5-inch with a low power eyepiece — the wide-field view is spectacular.(Saturday, September 2025)
