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.
M20 Trifid Nebula and M21 star cluster above it, 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 8 minute exposures at ISO 800. Taken from Coonabarabran, NSW, Australia, April 24, 2007. Some trailing from scope aimed straight up and axes wandering -- some guiding error introduced that fattened stars and some passing thin cloud added glows to stars.
M24, Small Sagittarius Starcloud. Taken with Borg 77mm f/4 astrograph refractor and Hutech-modified Canon 5D for stack of 5 x 8 minute exposures at ISO 400. Taken from Coonabarabran, NSW, Australia, April 18, 2007.
