Supernova 2011fe (PTF11kly or PSN J14030581+5416254)
I just got back from a dark-sky trip to Mahogany Flat Campground in Death Valley National Monument. I captured this image of the recently discovered supernova in Messier 101.

The image was taken with an unmodified Canon 5D Mark II through a Celestron 80ED refractor mounted piggyback on a C8 on a CGEM mount. I took 12 exposures each 5 minutes long for this shot. I combined & processed them using Nebulosity. I haven’t taken the time to get a magnitude from this photo, but comparing it to earlier photos, the supernova is definitely getting brighter very quickly.
