#astronomie on continue avec l'image de NGC4565 dite galaxie de l'aiguille (c'est une galaxie spirale vue par la tranche qui donne cette barre noire sur le bulbe) elle est pas mal non plus même si le suivi est un peu moins bon (étoiles légèrement ovales) j'ai du faire une déconvolution avec #siril pour améliorer un peu la chose. On voit une petite galaxie spirale à gauche NGC4562, les deux se trouve à un peu moins de 40 millions d'années lumière!

Horsehead nebula

60mins of 10second exposures with Seestar S50, processed in Siril. The moon was nearly full. This thing is good fun.

On the right, you can see a section of Orion: shoulders, belt, sword hanger with the Orion Nebula. The Flame Nebula also comes out well in the belt. To the left, there is not much to see, as a few hours of exposure are missing for impressive effects. However, a few deep sky objects can be guessed at.

I finally got to try out the new 70-210mm Soligor lens, which I got second-hand for €20. The image shows Orion's Belt with the Flame Nebula (NGC 2024) and – just a faint hint at the top centre of the image – the ‘Casper the Friendly Ghost’ Nebula (M 78).

I was "developing" a shot of #M81 and #M82 when I started to get side-tracked and got curious about those nifty #Siril scripts. Notably, the #Galaxy Annotation script. And oh boy, is it marvelous.

Here is a picture of M81 and M82, and _a lot_ of other stuff ... mostly blotches, but still... those are some exceptionally old photons!

Question; is this really what we are seeing here?

Zäh geht es mit der Ausarbeitung (mit #Siril) - ist bei Kometen etwas komplexer, da sie sich im Verhältnis zu den Sternen bewegen.

Hier nun die Animation von #Komet C 2025/R2 #Swan.
Aufnahmen erstrecken sich über 1 h 52 min.

#C2025R2Swan #KometSwan #Astrofotografie

Comet C/2025 A6 (Lemmon) (bottom of the image) and Gemma (main star in the constellation Corona Borealis) (top of the image) on 24 October at 20:33 CEST from Wedemark, north of Hanover, Germany.

The straight, bluish plasma tail is visible over a length of ~6° (12 full moon diameters). The curved dust tail is a lot shorter.

Crop from a stack of 51 2-second images at ISO 5000, f/2.8, and f=200 mm.

Komet C/2025 A6 (Lemmon) (unten) und Gemma (Hauptstern im Sternbild nördliche Krone) (oben) am 24. Oktober um 20:33 Uhr MESZ aus der Wedemark nördlich von Hannover.

Der gerade. bläuliche Plasmaschweif ist über eine Länge von rund 6° (12 Vollmonddurchmesser) erkennbar. Der gebogene Staubschweif ist deutlich kürzer.

Comet C/2025 A6 (Lemmon) on 24 Oktober at 20:28 CEST from Wedemark north of Hannover, Germany.

Cropped from a stack of 51 single exposures of 2 s at ISO 5000, f/2.8, and at f=200 mm.

Used Siril, Gimp, and NeatImage to improve stacked image afterwards.

Edit: Added newly edited version of the image with less color shift added.

Przez trzy noce polowałem. Polowałem na dziury w chmurach.
Pierwsza noc to zaledwie 20 minut, drugiej nocy wyszło około 1h17m. Z prognoz pogody wychodziło mi, że z 31.05 na 01.06 nic się nie da wypalić, bo chmury i deszcz. Po północy okazało się, że niebo jest czyste i szybko wystawiłem i ustawiłem sprzęt. Z odpalonym antistorm.eu i WheatherRadar i sprawdzaniem co chwilę wszystkiego naocznie, dopaliłem 1h45m.
Z całości Siril złożył 548 klatek po 20 sekund, czyli nieco ponad 3 godziny.
Przed Państwem The Eastern Veil Nebula[1] aka NGC 6992 aka Ksenomorf. ;-)

Gdzieś coś przeczytałem, coś sprawdziłem, zastanowiłem się, doczytałem, pomyślałem i stwierdziłem, że może się uda.

97 klatek po 20 sekund każda złożone w jedno zdjęcie.

Po samym złożeniu nie zauważyłem interesującego mnie obiektu, ale gdy zrobiłem Backgroud Extraction, Denoising w GraXpercie to… chyba jest! Trochę edycji, zmian i…
Z dużą dozą prawdopodobieństwa 🫣😉oto TON-618 - kwazar.
Wikipedia:
„TON 618 (skrót od Tonantzintla 618) – kwazar zlokalizowany na granicy gwiazdozbioru Psów Gończych i Warkocza Bereniki, z przewidywaną odległością współporuszającą się około 18,2 miliarda lat świetlnych od Ziemi[1], światło przez niego emitowane obserwowane obecnie na Ziemi pochodzi sprzed około 10,4 miliarda lat. Posiada jedną z najbardziej masywnych czarnych dziur, jakie kiedykolwiek udało się zaobserwować, o masie 66 miliardów mas Słońca. Czarna dziura o takiej masie jak TON 618 posiada promień Schwarzschilda mierzący 1300 j.a. (średnica około 390 miliardów kilometrów, ponad 40 razy większa od orbity Neptuna)”[2]

Pan Marcin był chory
I leżał w łóżeczku
Wystawił więc Seestara,
By coś tam smażył w ogródeczku...
A co widział i wypalił znajdziecie na obrazeczku.

Znaczy na kilku, bo wychodzi na to, że mam 2h materiału (a 3h pracy) a od 8:30 do 16:30 się bawiłem w obróbkę i jest kilka wersji.

Celem miała być mgławica IC 1795[1], czyli Mgławica Rybia Głowa (Fish Head Nebula), ale po małej korekcie, jako cel została uznana gwiazda oznaczona jako HIP 11505.
Obróbkę robiłem za pomocą:
A) aplikacją do obsługi teleskopu Seestar S50
B) Siril 1.2.6+GraXpert
C) PixInsight z różnymi ustawieniami.

1) Obróbka aplikacją do obsługi teleskopu Seestar
2) Siril+GraXpert
3 i 4) PixInshight + GraXpert (2 wersje)

Czuję, że czeka mnie duży wydatek na PI+dodatki.
