Messier 17, the Swan Nebula, aka the Omega or Checkmark Nebula, with the open cluster M18 below it. I shot this from home on a very clear night (as this object is low for me) on July 29, 2019, using the Astro-Physics Traveler and Hotech f/6 field flattener for a stack of 5 x 8-minute exposures at ISO 800 with the now 10-year-old filter-modified Canon 5D Mark II.
M17 Swan or Omega Nebula and M18 cluster below. Taken with 4-inch Astro-Physics Traveler apo refractor at f/6 with 6x7 field flattener, and Hutech-modified Canon 5D camera at ISO 800 for stack of 4 x 7 minute exposures. Taken from Coonabarabran, NSW, Australia, April 23, 2007. Some trailing from scope pointing straight up and causing guiding errors as scope wandered from being too in balance.
