M16 Eagle 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 7 minute exposures at ISO 800. Taken from Coonabarabran, NSW, Australia, April 23, 2007. Taken with scope aimed almost straight up, creating some wobble and guiding error, so slight trailing visible.
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.
