Totally Unexpectedly I was presented by a clear window on Thursday, late evening I took advantage and grabbed this observation.
NGC 6309, the Box Nebula, is a planetary nebula in the constellation of Ophiuchus. It’s a fairly dim target, having a mean surface brightness of only 11.0. I was drawn to observe this after my friend Frank McCabe had observed & sketched it 24hrs before from Chicago, that sketch can be seen in his file on this web site.
I made this sketch using the 505mm mirror & Watec 120N+ video camera on a barely dark mid summer night 28th June 2012. North is up, East is left.
Note the slightly ‘Mummy’ shape to the nebula, the mottling and dust lanes visible distinctly along the western upper edge. Also some nebulosity can be seen streaming to the east. View my sketch here

Hope you find my observation of this distant stellar remnant in our galaxy interesting?
