The spectacular field of Messier 8 and 20 emission and reflection nebulas in Sagittarius, with M8, aka the Lagoon Nebula below, and M20, the Trifid Nebula, above, all set in the rich starfields of the Milky Way. The diffuse nebula left of M8 is NGC 6559. Two globular clusters, NGC 6544 and NGC 6553, sit below and to the left (east) of M8. The Messier open cluster, M21, sits above M20. I shot this April 4, 2016 from the Tibuc Cottage at Coonabarabran, NSW, Australia, using the 77mm Borg f/4 astrograph for a stack of 5 x 6-minute exposures with the filter-modified Canon 5D MkII at ISO 1600.
M8 Lagoon Nebula, with Astro-Physics Traveler 4-inch apo refractor with telecompressor at f/4.5 with Canon 20Da camera, for 3.5 minutes each at ISO800. Stack of three exposures. Taken from Coonabarabran, NSW, Australia, July 2006. Slight trailing and soft focus.
M8 Lagoo Nebula, taken with 4-inch Astro-Physics Traveler refractor at f/6 with 6x7 field flattener and Hutech-modified Canon 5D camera for stack of 4 x 16 minute exposures at ISO 400. Taken from Coonabarabran, NSW, Australia, April 24, 2007. Scope aimed nearly straight up for this, causing some trailing and guiding error.
