Small Magellanic Cloud field -- NGC 241 area (largest cluster on chart but not conspicuous here) -- with two nebulas being NGC 261 and 249 (right). Numerous other clusters in field. Taken July 30, 2006 from Queensland, Australia. Taken with 4inch Astro-Physics Traveler apo refractor at f/6 with Canon 20Da camera at ISO800 for 6 minutes each. Stack of two exposures. Object still fairly low in sky.
The Coal Sack and Jewel Box Cluster area on the east side of Crux, the Southern Cross. The Coal Sack, which to the eye looks like a large dark patch, under photography breaks up into small patches, the darkest just south of the Jewel Box Cluster, here just below and left of Becrux, or Beta Crucis. Other star clusters in the scene are NGC 4852 at top left, Trumpler 20 at right. and NGC 4609 at lower centre. The cluster at far right above Acrux is NGC 4349. The small intensely red area left of centre is the nebula Gum 46. The star at lower right is Acrux, Alpha Crucis. This is a stack of 5 x 8 minute exposures with the Borg 77mm astrographic apo refractor (330mm focal length) at f/4.3 and with the filter-modified Canon 5D Mark II at ISO 800. Taken from Coonabarabran, Australia, March 2014.
