#Comet #12P #PonsBrooks below Jupiter sinking into the murk on April 11. Probably my last opportunity for this one

Turn your eyes to the sky for a two-for-one astronomical spectacle as the 'devil comet' finally creeps into view for the southern hemisphere just in time for the Lyrid meteor shower! ☄️
The Comet Pons–Brooks is visible to the naked eye, but only if you know where to look.

#Comet #12P #PonsBrooks (bottom center) below the #Moon last night, a bit later, more exposure and more frames than the previous shot. Again somewhat fake: Composite of the same stack aligned separately on the moon and stars.
Also visible: #Jupiter, Callisto, Ganymede, maybe Europa if you squint at the glare around Jupiter, and #Uranus (relatively bright blueish object almost directly above Jupiter)

The green color seen in the coma of most comets, but not in their tails, is due to emissions from Diatomic carbon C2 (aka dicarbon) molecules.
Sunlight heats the comet’s ice and organic material to produce C2 molecules, which break apart in ~2 days before they reach the tail. C2 is excited by solar UV radiation and emits mostly in infrared but its triplet state radiates at 518 nm (d3Πg → a3Πu transition below).

#Comet #12P #PonsBrooks (very faintly visible, upper left) over the #Moon last night. This is a somewhat fake composite of 100 4 second frames, aligned separately on the stars, moon and foreground. Too close to twilight to get much of the comet

Too bad: The clouds were eventually gone, but when it finally got dark enough to make out #Comet12p #PonsBrooks on the photos of my amateur camera, it disappeared behind the trees. So, no chance of getting a shot of its tail. 🙁
Still: A nice constellation of the crescent Moon, Jupiter (with three of its own moons), and Uranus. 🙂

Spektakel am Himmel: So seht ihr den Kometen Pons-Brooks am besten
12P/Pons-Brooks ist ein seltener Komet, der nur etwa alle 71 Jahre zu sehen ist. Wie und wo das heute in Deutschland möglich ist, hier lesen!

#Timelapse of the frames used for that #Comet #12P #PonsBrooks shot up thread. So many more satellites, a few years ago I'd expect maybe 3-4 or in a shot like this. Doesn't really affect anything in this case (unlike the airplanes, which were bright enough to show up in a 240 frame average after stretching) but definitely noticeable
