The Pleiades star cluster, or Seven Sisters, aka Messier 45, in Taurus. The brightest part of the reflection nebula around the Pleiades at bottom is the Merope Nebula, IC 349. In this image. I’ve shot long exposures at low ISO speeds to record faint structure at low noise, to allow me to bring out the faint dusty nebulosity all around the region in processing. This is a stack of 10 x 12 minute exposures with the filter-modified Canon 5D MkII at ISO 400 through the TMB 92mm apo refractor at f/4.5 with the Borg. 0.85x field flattener/reducer. Taken from New Mexico, Nov 17, 2014.
The Pleiades star cluster, aka Seven Sisters, or M45, in Taurus. A deep exposure showing the reflection nebulosity which fills the area. This is a stack of 5 x 14 minute exposures with the TMB 92mm apo refractor and Borg 0.85x flattener/reducer at f/4.8 and Canon 5D MkII at ISO 800. Taken from home Oct 9/10, 2013.
A telephoto lens shot of the M50 to M46/M47 area of Canis Major-Monoceros border, simulating the field of binoculars. M50 is at upper ight, M46 & M47 at left edge. Red nebula is IC 2177 Seagull Nebula. Taken from Coonabrarbran, Australia, Dec 15, 2012. Some incoming cloud added glow from off-frame Sirius in corner of frame. This is a stack of 2 x 5 minute exposures at f/2.8 with the 135mm lens and Canon 5D MkII at ISO 800. Field also contains clusters NGC 2360 and NGC 2353, and nebula NGC 2359 Thor's Helmet.
