Nice one!
Great work tightening down the margins of error on the distance measurement (always hard in astronomy). NGC 6397 is actually a very nice object even in binoculars. I spotted it from down-under when I was a guest at the CSIRO in Sydney, back in May 2011. Would have loved to have brought the telescope, but even with binoculars, the southern skies are just fabulous
