NGC 104 or 47 Tucanae globular cluster, the finest in the sky, on the edge of the Small Magellanic Cloud. Taken from Timor Cottage, Coonabarabran, NSW, Australia, December 12, 2010. This is a stack of 5 x 6 minute exposures at ISO 800 with Canon 5D MkII camera on 105mm Astro-Physics Traveler apo refractor at f/5.8 with 6x7 field flattener.
NGC 185 (left) and NGC 147 (right), two distant companion galxies to the Andromeda Galaxy, located over the border in Cassiopeia. Both are dwarf elliptical galxies. This is a stack of 10 x 7 minute exposures at ISO 800 with the Canon 5D MkII and TMB 92mm apo refractor at f/4.4 with the Borg 0.85x field flattener/reducer. Taken from New Mexico, Dec 23, 2014.
The open star cluster NGC 188, in Cepheus, one of the oldest such objects known, with an estimated age of 9 billion years. NGC 188 has lasted so long as it is well above the plane of the Galaxy near the North Celestial Pole, and so free of the disruptive tidal effects of the Milky Way. This is a stack of 6 x 4-minute exposures with the AM 106mm refractor with the Hotech field flattener for f/6 and Canon 6D MkII at ISO 1600. Star glows added with Luminar and diffraction spikes added with Astronomy Tools
