M16 and M17 with 4-inch Astro-Physics Traveler apo refractor at f/6, with Hutech-modified Canon 5D at ISO800 for 7 minutes, stack of two exposures. Taken from Coonabarabran, NSW, Queensland, July 2006.
M16 and M17 Nebulas, taken with 77mm Borg astrogrpahic refractor at f/4.3 and Hutech-modified Canon 5D camera for stack of 4 x 10 minute exposures at ISO 400. Taken from Coonabarabran, NSW, Australia, April 17, 2007. Scope aimed straight up and so mount wandering somewhat with guiding errors. Focus slightly soft from temperature change thru the night (this was taken at the end of the night).
Messier 16, the Eagle Nebula in Serpens. The cluster embedded in the nebula is NGC 6611. The small open cluster above is Trumpler 32. I shot this from home on a very clear night on July 31, 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.
