Patrick Duis, one of the amateur astronomers from the Dutch Astroforum, took another picture of Hanny’s Voorwerp. Now I know there are others out there who’d like to give it a try too, so if you have: do let me know. Here are the specifics Patrick has e-mailed me, and of course the pretty picture. Thanks!
