M20 Trifid Nebula
with Sky-Watcher Quattro 250P Newtonian telescope
The Trifid Nebula (M20) are adjacent red emission and blue reflection nebulae in the Sagittarius Milky Way, This is a joint collaboration where James Foster photographed, stacked and did preliminary processing on the image taken in Frazier Park California and Michael Stecker did the post-processing from Los Angeles.  A Sky-Watcher 250P, 10-inch f/4 Newtonian, telescope was used.
