A transparent sky still didn't allow much of a result with the faint and irregular spiral arms of NGC 6140 and I had to push the processing hard to get an image worth posting. Probably one that needs something better than MK has to offer. NGC 6140 is a barred spiral in Draco and at mag.12 would have benefited from a few more subs I guess. Details: 10" f4.3 Newt. 10x 10minute exposures @ iso1600 with CLS in DSS, FIV, CS2 & XAT.5.6.11
