M8 & M20 Lagoon & Trifid Nebula
M8 & M20 Lagoon & Trifid Nebula
This target is especially low at around a max altitude of 20° to the south, but was able to grab 6 hours total on this target in Sulfur, Hydrogen, and Oxygen narrowband. It turned out to have a lot of pretty good signal. M8 Lagoon in the lower right appears to be spilling over with Oxygen while M20, the Trifid nebula, in the top right sits by. To the left is NGC 6559, sometimes referred to as the chinese dragon nebula, wit it’s dark dust patterns.
