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

    #Astrophotography #Astrodon

  2. #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)

  3. #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

  4. #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

  5. #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)

  6. 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).

  7. O.k., according to 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.

  8. How convenient: #Comet 12P #PonsBrooks was “visible” from our living room window tonight right after dinner. So I took the chance to take some photos with my hobby equipment, which is hardly made for #astrophotography (at least I had a Bahtinov mask to help focussing).

    Camera: #FujifilmXT2 mirrorless
    Lens: #Fujinon #XF150to600 @ 600mm F/8

    This is a stack of 8 photos, processed by hand in Adobe Photoshop.

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

  10. 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…

  11. 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): twitter.com/Komet123Jager/stat and facebook.com/photo/?fbid=72607

  12. 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 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 ...!

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