M108, a Barred Spiral Galaxy, is a very distant galaxy. It is about 46 million light years away. Keep in mind that light travels 186,000 miles every second. And a light year is how far that light would travel in a year of seconds. That's pretty far, right? But this galaxy is 46,000,000 light years away. That explains why it appears not quite as sharp as some of the other galaxies imaged here. Remember that a spiral galaxy is shaped more or less like a huge plate. But M108, in this image, looks to be the shape of a cigar. That's because we are viewing M108 from its side view. A little bit of zooming in on your display will reveal hints of the brown dust lanes in the galaxy. You can see a galaxy's dust lanes in much more detail by looking at the M31 Galaxy image in this Flickr collection; it's only 2.5 million light years from us. The good eye looking closely at M108 will also see little hints of blue. Those are areas of active star formation within M108.

Taken on 18 April 2019 at 02.32 pm bst with Celestron NexStar 6se telescope and ZWO ASI224mc camera, using Baader Solar filter and Skywatcher H-alpha CCD filter, the latter to give a narrow band light to prevent chromatic aberration.

Video was captured in SharpCap. Unfortunately, it was in raw8 mode so had to be debayered in PIPP before being processed in Autostakkert 2 and Lightroom, so gave this peculiar pink colour, but got to like it in the end!

La Lune, cible attrayante et facile pour tous les observateurs, recèle quelques observations originales dont le X lunaire fait partie.

Mais son apparition est … fugace !

Le X lunaire, aussi connu sous le nom X de Werner (ce phénomène se produisant près du cratère Werner)

Le X lunaire n’est pas une formation géologique comme le sont les failles, les cratères ou les mers.

Il s’agit d’un jeu de lumière visible durant quelques heures au terminateur (la frontière entre la partie éclairée et la partie sombre de la Lune), un peu avant le premier quartier.

Ce jeu de lumière se présente, sous la forme d’une croix se formant à l’intersection des cratères Purbach, La Caille, Blanchinus et Regiomontanus, qui sont situés grosso modo au centre de la moitié sud du disque lunaire.

La recherche du X lunaire vous amuse ? Sachez qu’une autre lettre de l’alphabet apparaît à peu près au même moment : un V ! Il est situé plus au nord, toujours en avant du terminateur

les avez vous trouvé ?

la prochaine fois qu'ils seront visible le 8 avril 2022 entre 22h00 et 0h00 (ils sont observables aux jumelles)

M33 is a spiral galaxy 2.73 million light-years from Earth in the constellation Triangulum. The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Milky Way and the Andromeda Galaxy. It is one of the most distant permanent objects that can be viewed with the naked eye.

The galaxy is the smallest spiral galaxy in the Local Group and it is believed to be a satellite of the Andromeda Galaxy due to their interactions, velocities, and proximity to one another in the night sky.

Image of Mars from the evening of 4 June 2016, at about 22:30 local time (02:30 UT). Mars was a mere 20 degrees or so above the southern horizon, and the seeing (absence of atmospheric turbulence) was given as 3/5. Shot wit a SC11 f/10 telescope, a ZWO120mm-s planetary camera, and a 2X barlow lens (thus f/20). Three AVI captures of 3 minutes each were made with IR, Green, and Blue filters, yielding this final image. Just right of center, one sees the region around the huge Valles Marineris canyon, left of which is the vast Tharsis region. At the top and left, the north polar region can be made out. And clouds seem to cling to the right limb area of the planet. Software used were: SharpCap, VirtualDub, AutoStakkert2, PixInsight and Photoshop CS3.

Une image de Mars réalisée le soir du 4 juin 2016, vers 22h30 local (02h30 TU). Mars dépassait à peine 20 degrés d'élévation dans le ciel du sud. Le seeing (qualité du ciel mesurée par l'absence de turbulence atmosphérique était fixée à 3/5, soit moyen). Photographié avec un télescope SC11 f/10, une caméra planétaire ZWO120mm-s, et un barlow 2X (donc f/20). Trois captures AVI ont été faites de 3 minutes chacune avec des filtres Infra-rouge, Vert et Bleu, donnant cette image finale. Juste à la droite du centre se trouve la région de l'immense canyon Valles Marineris, à la gauche de laquelle s'étend la vaste région de Tharsis. En haut du disque, à gauche, l'on aperçoit la région de la calotte polaire nord. Beaucoup de nébulosité est visible tout le long du limbe droit de la planète. Les logiciels utilisés sont: SharpCap, VirtualDub, AutoStakkert2, PixInsight et Photoshop CS3..

On the 3rd june 2017, two moons cast their shadows on the cloud tops of Jupiter. One of the moons, io, is visible in this image, the reddish dot a bit to the right, on the North Equatorial Band. Its shadow is near the left limb, on the same band. Higher up on the left limb is the stretched out shadow of another moon, Ganymede, off to the right of Jupiter, just outside the field of view. The moons and shadows slid slowly to the right as the evening went on. The image was shot with a Celestron f/10 SC11 telescope, fitted with a 2X barlow lens (therefore f/20), and a ZWO 120mm-s planetary camera. Three 90-second AVI sequences were shot using in quick succession infrared, green, and blue filters, each AVI containing between 1500 and 2500 frames. The resulting three grayscale images were derotated and combined as a final RGB image. The final image was downsized fro 525 to 425 pixels. Software used were SharpCap, Castrator, AutoStakkert2, PixInsight and Photoshop CS3. Sky conditions were not particularly good during this session, and Jupiter, this spring, is somewhat low in the southern sky, making for rather challenging photography.

Le soir du 3 juin 2017, deux lunes projetaient leurs ombres sur la surface nuageuse de Jupiter. L'une d'elle, io, petit disque rougeâtre, apparait un peu à la droite sur la Bande Équatoriale Nord. Son ombre apparaît sur la même bande, plus à gauche, pas loin du limbe. Plus haut, touchant presque le limbe gauche de la planète, l'on voit l'ombre étirée d'une seconde lune, Ganymède, celle-ci étant juste à l'extérieur du champ de l'image, à la droite de Jupiter. Lune et ombres se déplaçaient lentement vers la droite durant la soirée. L'image a été réalisée avec un télescope Célestron SC11 f/10, muni d'un barlow 2X donnant f/20, et une caméra planétaire ZWO 120mm-s. Trois séquences AVI de 90 secondes chacune, et comptant de 1500 à 2500 clichés, ont été faites en rapide succession, les trois images monochromes étant ensuite dérotationnées, puis combinées pour donner l'image RGB finale. L'image finale a été réduite de taille de 525 à 425 pixels. Les logciels employés sont SharpCap, Castrator, AutoStakkert2, PixInsight et Photoshop CS3. Les conditions du ciel étaient plutôt médiocres pour cette séance photo, et la planète Jupiter, ce printemps, se retrouve plus basse dans le ciel que l'année dernière, rendant d'autant plus difficile la photographie.

I embarked on a mammoth lunar imaging session on 10th February so I could produce an animation showing the sunrise over some prominent craters. I've already shared the video I created with the data but am now sharing the still images. If you didn't see the animation you can watch it here:

flic.kr/p/2n38rfm

I was imaging from15:45 UT until 22:30 UT and during that time the Moon changed its illumination from 69% to 72%.

Taken from Oxfordshire with a William Optics 70mm refractor and ASI120MC camera through a Celestron 3x Barlow. A 2,000 frame video was shot with SharpCap and depending on the quality graph I stacked either 50 or 25% of the frames using Autostakkert! 3. Processing with Lightroom and Fast Stone Image Viewer.

Taken from Oxfordshire, UK with a William Optics 70mm refractor, on an EQ5 Pro mount on a permanent pier. Camera used was a ZWO ASI120MC with a 2x Powermate Barlow attached to the camera nose.

I bought this mount and telescope around 3 years ago and I've slowly been upgrading everything else since then. To make sense of the rat's nest wrapped around the tripod I made a [cable diagram showing the connections between each piece of gear](i.imgur.com/ZXfNaIE.png). Not much has changed since last summer, except for the addition of a Sulfur filter and some rework of the cabling. For the last year and a half I was shooting from my apartment roof in downtown Athens, GA. Since I've graduated college and moved away, I now at least get to shoot from bortle 6, rather than bortle 7 skies.

The Andromeda Galaxy, also known as Messier 31, M31, or NGC 224, is a barred spiral galaxy approximately 2.5 million light-years from Earth and the nearest large galaxy to the Milky Way. The galaxy's name stems from the area of Earth's sky in which it appears, the constellation of Andromeda, which itself is named after the Ethiopian (or Phoenician) princess who was the wife of Perseus in Greek mythology.

The virial mass of the Andromeda Galaxy is of the same order of magnitude as that of the Milky Way, at 1 trillion solar masses (2.0×1042 kilograms). The mass of either galaxy is difficult to estimate with any accuracy, but it was long thought that the Andromeda Galaxy is more massive than the Milky Way by a margin of some 25% to 50%. This has been called into question by a 2018 study that cited a lower estimate on the mass of the Andromeda Galaxy, combined with preliminary reports on a 2019 study estimating a higher mass of the Milky Way. The Andromeda Galaxy has a diameter of about 220,000 ly, making it the largest member of the Local Group in terms of extension.

The Milky Way and Andromeda galaxies are expected to collide in around 4-5 billion years, merging to form a giant elliptical galaxy or a large lenticular galaxy. With an apparent magnitude of 3.4, the Andromeda Galaxy is among the brightest of the Messier objects, making it visible to the naked eye from Earth on moonless nights, even when viewed from areas with moderate light pollution.

An attempt to capture night side of Venus - a reprocessed a video taken on 2 March 2017 at approx 18.00 ut, with NexImage 5MP Camera & Celestron NexStar 6 SCT. AVI video captured in SharpCap, processed in Autostakkert and touched-up inc desaturation in Registax 6 and PS CC.

It appears to show a faint glow on the night side of Venus, the phenomenon known as ashen light but it could just be telescope/camera artefact and effects of the Earth's atmosphere.

We captured Mars on Jan 5, 2023 at about 8.23 pm local time using our C8 Edge telescope with a 2x Powermate to get a focal length of 4064mm. We used our Planetary color camera ZWO ASI178 MC and SharpCap software to capture several 4 minute videos at 60 fps. At the time of taking this video, the martian feature of Syrtis Major & Hellas basin were quite nicely placed. This image captures several of the darker "Mare" areas (dried up sea beds) and higher land lighter areas including the Hellas Basin.

Our image shows these features clearly and also captures the Borth polar hood/cloud structure at the top of the image. However, there is a "rind" artifact along the top edge which we could not remove. We used SharpCap to acquire 4 minute videos at 60 to 65 fps. We then stacked the best 3800 frames out of the 15,500 frames of the video to create this image. Enjoy!

j'ai pas mal hésité à publier cette image, et puis je me suis dit pourquoi pas, bon elle est mal cadrée, c'est plus un essai que j'ai fait cette nuit là

donc voici une image d'une nébuleuse portant le numéro SH2-129, autrement appelé la nébuleuse de la chauve-souris en vol. C'est une nébuleuse en émission de type région HII située à environ 1300 années-lumière de la Terre dans la constellation de Céphée.

en fait, je voulais vois si avec mon setup j'arriverais à faire ressortir OU4 une autre nébuleuse qu'on peut distinguer au travers (bon j'y croyais pas trop au départ, même pas du tout).

OU4 est connue sous le nom de nébuleuse du calamar géant, c'est une nébuleuse planétaire située à environ 2300 années-lumière de la Terre, et découverte que très récemment (2011) par Nicolas Outters.

Object Details: As Jupiter begins to enter our evening skies here in the northern hemisphere, prior to starting another planetary imaging season this year I thought it best to make some additional room on my harddrives and take a first look at processing some additional images I took last summer and never got a chance to examine.

Therefore as noted in the text accompanying the composite of Saturn taken later the same evening after the seeing had improved from 'horrible' to only 'terrible' ;) (linked here -

www.flickr.com/photos/homcavobservatory/51007634042/

) the conditions that evening were challenging to say the least. Never-the-less, please find attached a composite showing how Jupiter appeared on the evening of September 4, 2020 through luminance, infrared & methane filters.

Image Details: Taken at the HomCav Observatory using a 3X Televue barlow with set of specialized planetary filters on a vintage 1970, 8-inch, f/7 Criterion newtonian reflector with an ASI290MC' planetary camera / autoguider', like other planetary images posted previously, the scope was mounted on and tracked with a Losmandy G-11 running a Gemini 2 control system.

As presented here, the individual shots have been resized down to 50% of their original size and processed using a combination of Reistax, & Paint Shop Pro. I'm looking forward to seeing what changes may have occurred in Jupiter's clouds deck over this past year.

Wishing clear, calm and dark skies to all !

One of my best images to date of Jupiter, shame the red spot was not in view.

The moons from left to right are Calisto, Ganymede, Europa (about to transit Jupiter) and Io to the far right.

Taken with C9.25, 178C camera, SharpCap. Processed with AstroSurface.

The Rosette Nebula is a star-forming region approximately 5,000 light-years from earth. It is located in the Monoceros Region of our MilkyWay Galaxy. It is approximately 130 light-years across and at the center contains the open star cluster NGC 2244.

I imaged the Rosette at two International Dark Sky sites over the course of three months from December 2019 - February 2020. In total, it is about 8.5 hours of data. The image is comprised of only broadband, visible light with no filters. I cropped in the image to provide a closer view of the detail.
