Open cluster pair of NGC 2451 (right), a bright loose cluster, and NGC 2477 (left), a fainter but very rich open cluster. The field is also filled with faint emission nebulosity. Taken from Timor Cottage, Coonabarabran, NSW, Australia, December 12, 2010. This is a stack of 5 x 6 minute exposures at ISO 1600 with Canon 5D MkII camera on 105mm Astro-Physics Traveler apo refractor at f/5.8 with 6x7 field flattener.
NGC 2477 (rich cluster at left) and NGC 2451 (loose cluster at right) thru 77mm Borg f/4 astrograph refractor and Canon 5D camera for stack of 4 x 4 minute exposures at ISO 800. Taken from Ryder Homestead, NSW, Australia, April 11, 2007.
This is a binocular field (roughly 10° wide) framing of the contrasting open clusters NGC 2477 (rich, top) and NGC 2451 (loose, bottom) in Puppis. This is a 4-image stack of 3-minute exposures with the 135mm lens at f/2.8 with the filter-modified Canon 5D MkII at ISO 800. This was taken in May 2011 from Atacama Lodge in Chile.
