Thought I'd post this today since it's in the news. A Japanese amateur astronomer just discovered a supernova within the galaxy. It's located near the bend in the spiral arm on the right side of this image, around 2:00 position. Yeah, sadly this was taken in mid-April, else it would have easily been captured :). It has gradually been getting brighter over the last few days, but won't be visible without a telescope. The light from that supernova explosion left this galaxy....... over 20 million years ago. 21 million light years distant.
Anyhoo... I did use a dedicated hydrogen alpha filter to capture those pops of hot pink in the spiral arms. This is my second attempt at a galaxy, got another that hasn't been posted yet.

Abell 21, Sh2-274 or The Medusa Nebula is a planetary nebula located in the constellation of Gemini. It was originally thought to be a Supernova remnant but later identified as a planetary nebula. It lies around 1,500 light years distant.
Data captured on 2nd January 2023 was added to that of March 2022.

I wanted a print worthy effort for this galaxy I've loved since I started getting interested in Astronomy 30 years ago. I think I've achieved it.
~10 hours of LRGB data combined and edited in PixInsight.
Stacked with Astro Pixel Processor, edit in PixInsight. First real night imaging with new Telescope. It's a beginning, and feeling good so far. Just starting to learn Pixinsight. Steep learning curve.

My second attempt at imaging the most spectacular globular cluster visible in the northern hemisphere. Taken using a Canon EOS Ra attached to a Stellarvue SV102ED2 telescope (focal length of 710 mm).
Boring technical details:
The image is a stack of eight sub-exposures totalling 25 minutes of integration time. I used three 5 min exposures and five 2 min exposures, all at ISO 1600. This allowed me to blend the stack so that the faint stars are visible without overexposing the core of the star cluster.

Object: Markarian’s Chain – 2022
Markarian's Chain is a grouping of galaxies that forms part of the Virgo Cluster. When viewed from Earth, the galaxies lie along a smoothly curved line. At least seven galaxies in the chain appear to move in concert, although others appear to be positioned by chance.
Near the center of the chain of there appear the pair of interacting galaxies NGC 4438 and NGC 4435, about 50 million light-years away, known to some as Markarian's Eyes or simply The Eyes

Meu primeiro registro da pequena (em tamanho aparente/angular) Galáxia do Sombreiro. O processamento foi bastante trabalhoso. Preciso estudar melhores formas de captação/processamento para essa galáxia. Neste registro estão somados frames captados em dois dias consecutivos, totalizando 6 horas e 38 minutos de exposição empilhados. Aproximadamente metade dos frames foram realizados sem filtro e a outra metade com o filtro Optolong L-eNhance.
"A galáxia do Sombreiro (Messier 104, NGC 4594), é uma galáxia espiral com núcleo brilhante rodeado por um disco achatado de material escuro, que fica a 28 milhões de anos-luz de distância. Essa brilhante galáxia é conhecida como sombreiro devido a sua aparência característica que se assemelha a um chapéu. A galáxia possui uma magnitude aparente de +8,3". Fonte: Wikipedia.org

Voici le résultat "final" du traitement de 54 poses de 30 secondes empilée de la comète NEOWISE photographiée le 18 juillet 2020 dans le Gers sous un beau ciel étoilée et avec peu de pollution lumineuse.
L'empilement des 54 poses permet de gagner en signal/bruit.
Le traitement a été fait avec le logiciel Pixinsight (avec darks, offsets et flats).
Afin de compenser le déplacement de la comète par rapport aux étoiles (même sur seulement 27 minutes, la comète c'est déplacée de plusieurs minutes d'arc), il faut une traitement dissociant
d'un côté les étoiles, et la comète d'un autre), les deux images obtenues sont ensuite fusionnées.
J'avais déjà publié une seule pose traitée dans Lightroom :
www.flickr.com/photos/philastro31/50128569966/in/datepost...
Cela permet de voir la différence et constater ce que l'on gagne à empiler des poses en astrophoto.
La comète C/2020 F3 n'est plus visible à l’œil nu maintenant et difficilement observable aux jumelles car elle s'éloigne rapidement du Soleil, elle ne devait revenir dans le sillage de notre étoile que dans 6800 ans.
On voit les deux queues, la plus lumineuse de couleur dorée composée de poussières et la deuxième de couleur bleue qui est composée de gaz et ions.

The Whale Galaxy NGC 4627 and 4631. Imaging telescope : Ikharos 8" RC SXH18 CCD L600x40 bin2 + RGB & Ha. Integration around 16 hours shot under moonless condition in semi urban skies. Home obbs Valencia.
NGC 4631 (also known as the Whale Galaxy or Caldwell 32) is an edge-on spiral galaxy in the constellation Canes Venatici. This galaxy's slightly distorted wedge shape gives it the appearance of a herring or a whale, hence its nickname. Because this nearby galaxy is seen edge-on from Earth, professional astronomers observe this galaxy to better understand the gas and stars located outside the plane of the galaxy.

En la imagen tomada con un telescopio remoto desde Namibia, de 590 mm f2.95, se observan dos formaciones estelares , por un lado la Nebulosa NGC 6188 que conforma los Dragones Luchadores de Ara y dentro de ella se encuentra el cumulo estelar NGC 6193.
La nebulosa de emisión NGC 6188 se encuentra a unos 4000 años luz en la constelación de Ara. Formas oscuras de bordes brillantes cruzan la polvorienta nebulosa.
NGC 6193 es un cúmulo estelar abierto con estrellas supermasivas y que dan lugar a una zona de reflexión en NGC 6188. Esta situado a 3800 años luz y en el se encuentra la estrella de tipo espectral O3 más cercana a nosotros, contiene 27 estrellas.
Son casi 5 horas de imágenes en H alfa y OIII, repartidas por igual, tomadas con una cámara FF QHY 600. El procesado se realizó principalmente con Pixinsight y se termino con PS.
Las tomas se hicieron entre abril y mayo de 2022 .
In the image taken with a remote telescope from Namibia, 590 mm f2.95, two star formations can be seen, on the one hand the NGC 6188 Nebula that makes up the Fighting Dragons of Ara and inside it is the NGC 6193 star cluster.
The emission nebula NGC 6188 is located about 4,000 light-years away in the constellation of Ara. Dark shapes with bright edges cross the dusty nebula.
NGC 6193 is an open stellar cluster with supermassive stars that give rise to a reflection zone in NGC 6188. It is located 3800 light years away and in it is the star of the spectral type O3 closest to us, it contains 27 stars.
There are almost 5 hours of images in H alpha and OIII, distributed equally, taken with a FF QHY 600 camera. The processing was done mainly with Pixinsight and finished with PS.
The shots were taken between April and May 2022.
