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

#Astrophotography #Astrodon

#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)

#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

#Astrophotography

#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

#Comet #12P #PonsBrooks last night. Proper tail now, even with my unguided 10 year old P&S (Canon G7 X, 240x5s, ISO 800, 100mm EFL, aligned on the comet and stacked with hacky #gmic scripts and tortured in #gimp)

#12P #PonsBrooks #dwarfii

Three protagonists of the evening sky!
#Jupiter (top left), #Mercury (bottom middle, just above the roof) and comet #12P #PonsBrooks right above the church tower. For those wanting to spot the #comet, this should give some guidance where to find it (as well as some impression on how bright it currently is).

O.k., according to https://cobs.si/obs/comet/484/ #comet #12P #PonsBrooks is now at ~4.9 mag. about one magnitude brighter than at the beginning of the month - but it's not easier to see because it's closer to the Sun now. Here is a picture - 2.5 seconds at f/2.8 and ISO 1600 - from Bochum, Germany, 1/2 hour ago; comet 16° above, Sun 15° below the horizon: the arrow marks the comet which appears essentially as a green dot. NLM in the area was 3.0 mag. at best, the comet not visible in 8x30 binoculars.

#astronomie courte fenêtre météo pour observer la #comete #12P malgré une Lune gibbeuse bien brillante. 12P est assez grosse pour être vue aux jumelles, assez large, facile à localiser, coma très diffuse avec un début de queue vers le zénith. Le Noyau est très faible au Maksutov 90mm à 30×. Pas eu le courage de faire de photo surtout avec la Lune, les conditions empirent dans les prochains jours +de Lune et comète basse sur l'horizon avant de plonger dans l'hémisphère sud...

Tried that #SpotTheStation again last night. I can report that shooting with the shutter open significantly affects results. #M31 and #Comet #12P are just smudges (as expected), but they're there

(You can also #SpotUranus if you know where to look)

Half an hour of live (!) images of #comet #12P #PonsBrooks earlier this evening (from 18:30 UTC) through three different optics: https://www.youtube.com/live/YyU91nwRaRM

M31 the #AndromedaGalaxy with #Comet #12P/PonsBrooks taken on 3rd March 2024. The pink at the bottom is part of the amazing aurora we had that night! Widefield shot taken with a Canon 1100D 50mm fixed lens, 20 x 10 seconds stacked in #Sequator

Noch ein Versuch Komet 12P/Pons-Brooks abzulichten. Diesmal zusammen mit der Andromedagalaxie. Hier sieht man ganz gut wie „hell“ der Komet aktuell ist.
Leider Dunst am Horizont, das macht das Bild nicht besser…

Erster Versuch Komet 12P/Pons-Brooks abzulichten.

Seeing beautiful photos of #comet #12P Pons-Brooks (by (X) @Komet123Jager) and then quickly trying to do the same with non-appropriate gear, in the direction of the city center, is a 100% #WillyWonkaExperience. However, it is faintly visible (before image compression). Zoomed in and after background reduction, a green ‘smudge’ appears.

O.k., here is what #comet #12P #PonsBrooks looks like these days with *advanced* astrophotography gear ... worlds apart from what small cameras, let alone binoculars under poor skies, reveal. Sources (with technical detail): https://twitter.com/Komet123Jager/status/1764214049468727358 and https://www.facebook.com/photo/?fbid=7260774970704780

Yay, picked #comet #12P #PonsBrooks out of super-bad skies over #Bochum, Germany, with a #superzoom camera - on a tripod with a few seconds exposure - an hour ago. According to https://cobs.si/obs/comet/484/ the total coma magnitude is ~5.9 right now. 11x70 binoculars, normally quite good with comets, showed exactly nothing in this "sky" with a naked-eye limiting magnitude of ~2.3 - but the €300 camera saved the day, err, evening. 12P could get another 2.5 mag. = a factor 10 brighter: yes, please ...!

The #comet #12P #Pons-Brooks is still undergoing outbursts now and then - but not as dramatic as last summer & fall: https://nickdjames.com/Comets/2024/12P_lightcurve_9arcsec.png - and is now more interesting for a structure-rich plasma tail and a faint dust tail fan to its right. But beware: these images were taken - this morning: https://spaceweathergallery2.com/indiv_upload.php?upload_id=203709 and https://spaceweathergallery2.com/indiv_upload.php?upload_id=203704 - by Michael Jäger with an 11-inch telescope under excellent conditions! The total coma magnitude is now 7.5-ish, rising nicely: https://cobs.si/obs/comet/484/

Important light curve of #comet #12P #Pons-Brooks with a 30" aperture, so after each of the outbursts the brightness falls back to a baseline - which is increasing smoothly: https://twitter.com/katsumi_comet/status/1747654905215824170. Still no real clue what the *total* brightness will be in March and April - and during the total solar eclipse on April 8th.

Checking in on #Comet #12P #PonsBrooks … still there, still pretty faint

Tonight in low-tech #Comet hunting: #12P #PonsBrooks is there (center), and that's about all I can say about that
