Saturn June 12, 2022
This is an L-RGB image of Saturn. As luminance I used the zwo asi 290mm & optolong IR pass and for the RGB my trusty zwo asi 224mc with an atmospheric dispersion corrector. Given the bad conditions I experienced that night this result is pretty good. Definitely not my best image of the ringed planet this year but still deserves a post. Stay tunned cause far better images of Saturn are coming!
Let me know if you like it 😊
Equipment:
C11 XLT
ZWO ASI 224mc
Zwo ASI 290mm mini
Baader uv/ir cut filter
Optolong IR Pass
ZWO ADC

Messier 51, The Whirlpool Galaxy in the constellation Canes Venatici.
It’s amazing what one can get with a bit a of effort and patience. I never imagined being able to use a 11 inches telescope to get into a distant galaxy, probably one of my favorite, and get such a cool photo. I’m really pleased with the result. Overall I think I got a lot of details on the arms of this majestic spiral galaxy and the color is great. I really hope everyone like it! 😊

Jupiter and Io July 2, 2022 / UT: 04:13
First nice image of the Gas Giant this year! We are still far from opposition but you can start getting great images of Jupiter in July. In fact this image could be way better but seeing was just below average and that limited the result. Anyway, there are many details visible and the Great Red Spot is near the center. I also got some minor details on Io. There are also some changes in the atmosphere in comparison with last year. The north temperate belt has reduced and there are few barges in comparison with some images I took last year in July.
I hope to get better images soon as I absolutely love this ever changing world!

The Triangulum Galaxy
From Wikipedia: "The Triangulum Galaxy is a spiral galaxy 2.73 million light-years (ly) from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC 598. The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Andromeda Galaxy and the Milky Way. It is one of the most distant permanent objects that can be viewed with the naked eye. "
Took this one last year and did not like it. Found it in my disk again and said to myself. It may not be the best image but distant galaxies are somehow even more amazing than other interstellar objects as they are home to trillion of stars and even more planets where could be extraterrestrial life.
So here it is. Hope you enjoy it.

Ce soir on voyage du côté de deux galaxies, M81 (à droite) et M82 (à gauche).
.
M81, souvent nommée Galaxie de Bord, en référence à son découvreur Johann Elert Bode, est une énorme galaxie spirale. Située dans la Grande Ourse, serait située à 12millions d'années lumières de nous et aurait un diamètre de 87 000 années lumières.
.
M82, appelée galaxie du Cigare est également une galaxie spirale et avec cette fois un plus petit diamètre, de 42000 années lumières. Niveau distance elle est plus ou moins équivalente à sa voisine. On peut remarquer une énorme expansion rouge au niveau de cette galaxie, ce rouge étant de l'hydrogène ionisé.
.
Cette photo de ce duo fait probablement partie des plus belles photos de galaxies que j'ai jamais pu réaliser auparavant.

Hubble determines mass of isolated black hole roaming our Milky Way. Astronomers estimate that 100 million black holes roam among the stars in our Milky Way galaxy, but they have never conclusively identified an isolated black hole. Following six years of meticulous observations, the NASA/ESA Hubble Space Telescope has, for the first time ever, provided direct evidence for a lone black hole drifting through interstellar space by a precise mass measurement of the phantom object.
Until now, all black hole masses have been inferred statistically or through interactions in binary systems or in the cores of galaxies. Stellar-mass black holes are usually found with companion stars, making this one unusual.
The newly detected wandering black hole lies about 5,000 light-years away, in the Carina-Sagittarius spiral arm of our galaxy. However, its discovery allows astronomers to estimate that the nearest isolated stellar-mass black hole to Earth might be as close as 80 light-years away.
Black holes roaming our galaxy are born from rare, monstrous stars that are at least 20 times more massive than our Sun. These stars explode as supernovae, and the remnant core is crushed by gravity into a black hole. Because the self-detonation is not perfectly symmetrical, the black hole may get a kick, and go careening through our galaxy like a blasted cannonball.
Telescopes can't photograph a wayward black hole because it doesn't emit any light. However, a black hole warps space, which then deflects and amplifies starlight from anything that momentarily lines up exactly behind it.
Hubble was used to measure the amount of deflection of the background star's image by the black hole. The astrometric microlensing technique provided information on the mass, distance, and velocity of the black hole.
