M19 globular cluster, in rich Milky Way star field of Ophiuchus near Antares. Shot May 5, 2013 from home with object very low in south in pre-dawn hours. This is a stack of just 2 exposures, 2 x 6 minutes at ISO 800 with the Canon 60Da and 130mm Astro-Physics refractor at f/6.
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.
