Order Notes

Very near the Lagoon Nebula is the Trifid Nebula (Messier 20).  The name comes from the apparent division into three lobes.  The Trifid also contains all three types of nebulosity:  The red is an emission nebula (mostly hydrogen), the blue area is a reflection nebula (dust reflecting light from nearby stars), and the dark areas all around it are “dark nebula” – dust that blocks the light from objects behind it.

Captured at Pine Mountain Observatory near Bend, Oregon in RGB.  This image was captured after completing some scientific imaging with students Katie, Jaclyn, and Samara, who helped in capturing this image as well.

About Greg Marshall

I am a retired electronics engineer and after a few months of enjoying my leisure I began to miss doing product development. My astronomy hobby always needed new solutions to unique problems, so I decided that whenever I came up with a good solution I would try to make it available to others.
