Object of the Week July 31st, 2016 - NGC 6445, the Box Nebula

[wvreeven]

Here are my notes from last Friday under an SQM 20.9 sky using my 20" telescope:

At 256x and OIII visible as a rectangluar nebula. The north west and south east sides are brighter than the north east and south west sides. Both bright sides have one or more brighter knots, especially the north western side. Further north west lies a faint star. A long, faint, extension is visible to the north east and a short, even fainter, extension to the south west.

Thanks for posting your observing, Wouter. Interestingly, I viewed the southwest facing loop (here's another image) but didn't see the northeast extension. In any case, I hope others take a look (and report results), as this planetary has an unusual structure!
