Last night the sky was quite clear, enabling me to capture a decent shot of Jupiter and its four large moons. There are actually 79 moons around Jupiter, but most are much smaller than these four.
The names of the four are: Io, Europa, Ganymede, and Callisto.
Jupiter is by far the largest planet in our solar system. All the other eight planets combined could fit into Jupiter and there would still be lots of room to spare!
Along Jupiter's equator, 13 earths could be lined up across its diameter.
Earth is the 3rd planet from the sun, and Jupiter is the 5th planet from the sun.
At 750mm with my telephoto lens (and a heavy crop in post processing), I'm happy with how clear I was able to render this planet and its moons. Considering my camera sensor was capturing light from 373 million miles away, it came out beautifully!

Monday night 2020-12-21 was special: 1) It's the day of winter solstice, 2) the Moon is at its first quarter, and 3) the great conjunction of Jupiter and Saturn. It’s been nearly 400 years since the two planets passed this close to each other in the sky. Jupiter and Saturn are actually 456 million miles (734,000 million km) apart. Saturn is nearly twice as far away as Jupiter.
I took a shot of the Quarter Moon at twilight, and after sunset a shot of Jupiter and Saturn with a 600mm long lens on a crop sensor camera, resulting in a long focal length of 900mm. I combined the two shots to scale. As you can see the planets appear to be much much smaller, even though they are ginormous compared to the moon.
If you zoom in and look carefully you can see 3 of the 4 moons of Jupiter.
For each shot, I processed a realistic HDR photo from a RAW exposure, and did some minimal curve adjustments. I welcome and appreciate constructive comments.

It took a while to get the dust off of my camera and do some shooting. But, was quite surprised that the ring around Saturn (diagonal ears) was visible along with four of Jupiter's moons. Looking forward to seeing some of the really great shots y'all will be getting.
400mm with a lot of digital zoom.

Jupiter’s moon Europa is a fascinating world. On its surface, the moon appears to be scratched and scored with reddish-brown scars, which rake across the surface in a crisscrossing pattern. These ‘scars’ are etched into a layer of water ice, which is thought to be at least several kilometres thick and covering a vast – and potentially habitable – subsurface ocean.
The scars seen in this view of the moon from the archives of NASA’s Galileo mission – based on images taken by the spacecraft in the 1990s – are a series of long cracks in its icy surface, thought to arise as Jupiter tugs at Europa and breaks the ice apart. The colours visible across the moon’s surface are representative of the surface composition and size of the ice grains: reddish-brown areas, for instance, contain high proportions of non-ice substances, while blue-white areas are relatively pure.
Scientists are keen to explore beneath Europa’s thick blanket of ice, and they can do so indirectly by hunting for evidence of activity emanating from below. A new study, led by ESA research fellow Hans Huybrighs and published in Geophysical Research Letters, did exactly this. Building on previous magnetic field studies by Galileo, the simulation-based study aimed to understand why fewer than expected fast-moving protons – which are subatomic particles with a positive charge – were recorded in the vicinity of the moon during one of the flybys of the moon performed by the Galileo probe in the year 2000.
Researchers initially put this down to Europa obscuring the detector and preventing these usually abundant charged particles from being measured. However, Hans and colleagues found that some of this proton depletion was due to a plume of water vapour shooting out into space. This plume disrupted Europa’s thin, tenuous atmosphere and perturbed the magnetic fields in the region, altering the behaviour and prevalence of nearby energetic protons.
Scientists have suspected the existence of plumes at Europa already since the times of the Galileo mission, however indirect evidence for their existence has only been found in the last decade. Excitingly, if such plumes are indeed present, breaking through the moon’s icy shell, they would offer a possible way to access and characterise the contents of its subsurface ocean, which would otherwise be hugely challenging to explore.
These prospects are of great interests to ESA’s upcoming Juice mission, planned for launch in 2022 to investigate Jupiter and its icy moons. Juice will carry the equipment needed to directly sample particles within the moon’s water vapour plumes and also to detect them remotely, aiming to reveal the secrets of its vast, mysterious ocean.
Scheduled to arrive in the Jupiter system in 2029, the mission will study the potential habitability and the underground oceans of three of the giant planet’s moons – Ganymede, Callisto and Europa. As this new study demonstrates, tracing the energetic charged and neutral particles in Europa’s vicinity offers huge promise in efforts to probe the moon’s atmosphere and wider cosmic environment – and this is precisely what Juice plans to do.
Olivier Witasse, ESA’s Juice project scientist, is also a co-author on the study, along with a number of ESA research fellows, including former Science Directorate fellows Lina Hadid and Olivier Lomax, Mika Holmberg, a research fellow in the Technology, Engineering and Quality Directorate.
The new study is based on data collected by Galileo during a flyby of Europa in 2000. The image comprises data acquired by the Galileo Solid-State Imaging (SSI) experiment on the spacecraft's first and fourteenth orbits through the Jupiter system, in 1995 and 1998, respectively, and was recently re-processed in 2014. The image scale is 1.6 km/pixel, and the north pole of the moon is to the right.

If a new savior is born, I hope it's a woman this time since the wise men are nowhere to be found. ;-)
Conjuncture of Jupiter and Saturn December 21, 2020.
Nonostante siano anni che studio il cielo ed il cosmo, mi sorprendo sempre di quanto ci sia ancora da capire, da sapere, da scoprire.
Un esempio: 340 anni fa, Ole Rømer, astronomo danese e assistente del matematico Erasmus Bartholin, fu tra i primi a misurare la velocità della luce.
Chiamato a Parigi da Giovanni Cassini per lavorare all’Osservatorio, proseguì con Jean Picard lo studio delle eclissi dei satelliti di Giove, fondamentali per il calcolo della longitudine.
Osservando che i tempi delle eclissi della luna Io variavano a seconda della distanza tra Terra e Giove, Rømer intuì che la luce viaggia a velocità finita.
Stimò che impiegasse circa 22 minuti per attraversare il diametro dell’orbita terrestre. Presentò la sua scoperta nel 1676 all’Académie des sciences. Oggi sappiamo che la luce impiega circa 16 minuti e 40 secondi.
E per arrivare a Giove, la luce solare ci mette circa 43 minuti.
Questa conquista dimostra come, con perseveranza e ingegno, l’umanità possa affrontare e vincere sfide immense della conoscenza.
In questa foto che ho scattato al telescopio si vede Giove, con il suo complesso sistema di nuvole, e 3 dei suoi satelliti, scoperti da Galileo Galilei a Venezia, nel 1610.

This enhanced-color view from NASA's Galileo spacecraft shows an intricate pattern of linear fractures on the icy surface of Jupiter's moon Europa. Newer fractures crosscut older ones, and several wide, dark bands are visible where the surface has spread apart in the past. The scene also contains several regions of "chaos terrain," where the smooth surface has been disrupted into jumbled blocks of material.
I missed last night the double transit due to some family commitments but I did get this one later in the evening. The air was very humid and the seeing started decent but deteriorated during the morning hours. Io can be seen very bright in the right and Europa on the left of the surface of Jupiter as a white spec, with its prominent Shadow across the planet. According to my measurements in Winjupos the shadow created is aprox 3600km in diameter. The image taken with a C11 and an ASI120MM camera using Astronomik RGB FIlters. 2X Barlow and captured using Firecapture
Two images taken with ASI294MC Pro camera in video mode and Sigma 150-600 @600; one exposed for Jupiter and one for the moons. ZWO ASIStudio to stack the videos. Blended in Photoshop and used Lightroom super resolution tool

Walking back to my car, I watched Jupiter rise in the Southeast. I knew that it would be very bright in June and wondered if I could see its moons at 200 mm. When I looked into my view finder, I started hopping up and down with excitement. Short of looking in a telescope, this was the first time I had ever seen these moons with my own camera equipment. The 4 largest of the 67 moons were there! Io, Europa, Ganymede, and Callisto!
I bracketed the shots for Jupiter as it was so darn bright compared to its moons. I manually aligned the bracketed shots of Jupiter using luminosity masks. I then blended it with the Jupiter moon shot taken in the same bracket sequence. Probably overkill for this small a view. While this image has been cropped, it can be enlarged further by pressing "L" or clicking on the diagonal arrows in the upper left-hand corner.
Conjunction of Jupiter and Saturn, the closest approach occurred last night but it was way too cloudy. At least two probable moons of Jupiter are visible, probably Callisto to its top left and probably Ganymede to its lower right. Some have theorized that this conjunction many years ago may have been the Christmas Star that the three Wise Men followed to Bethlehem.. The last time this happened was 800 years ago.
Taken with my Fuji x e2 and Tokina 400mm. It wasn't possible to get the detail in Jupiter and the moons in one shot so this is a composite of two, with the moons at a longer exposure than Jupiter.
Taken through the fug of London pollution so I'm pretty happy with this - especially given it's a £50 lens from ebay - must get out to a clearer sky and give this another go....

Jupiter and 3 or 4 of it's moons. First attempt at planetary imaging
20 1" ISO 640 f/3.2 200mm stacked using DSS to reduce overall noise. Took stack and single image and blended as I found Jupiter was not as good in the stack. Major crop to 762x761
I made an attempt to capture Jupiter and its moons from my apartment in the Denver, Colorado area. This was the best i could do with my 70-200mm lens.
Jupiter on Christmas day image made from some shots taken around 2am. Moons from bottom left to top right are: Callisto, Io, Ganymede and Europa.
Io has just exited from behind Jupiter while Callisto recently finished a transit of Jupiter's disc. Although no detail on the moons can be seen, note contrast of surface brightness and colour between Io ( on left ) and Callisto. Io is brighter with a subtle yellow colour. Refer to "Moons of the Solar System" graphic in this album.
Image captured with 9.25"sct, Moonlite focuser, Meade flip mirror, Zwo ASI120mc.
I'm experimenting with astrophotography without a telescope. I shot this with a Canon 70D with a Tamron 70-300mm lens on a tripod, with no other apparatus for focus or tracking.
I was thrilled that I could see three of Jupiter's moons!
A zoomed-in capture of Jupiter and four of its moons, referred to as Galilean satellites (Callisto, Europa, Io, and Ganymede), as seen from Heritage Park about an hour after sunset.
On this night, Jupiter will be at its closest to Earth in 59 years - a mere 367 million miles from our planet.

Transit of Io , 1 hour + condensed for this short clip.
Note Europa emerging from behind the great gas giant in last few frames.
The eclipse shadow during solar eclipse of the Luna/Earth system would look much like that of eclipsing Io on the surface of Jupiter.
Imaged by Redfish during subpar seeing at altitude Feb. 27,2016 with 9.25"SCT, ZwoASI120mc and processed using Castrator, Autostakkert2, Registax and JASC PSP.

Image after LR deconvolution and colour balance. Here the proper Gausian PSF was found as 3x3 at 15 iterations.
Sharp of moons completed with sharp tool at size 5 and minimal hard in JASC PSP8. Note lighter overall (yellowish) colour of Io compared to Callisto.
I missed the great conjunction in the night sky of December 21, however I did venture out last night (22nd) and got a good view of Jupiter and the moons Io, Europa, Ganymede, and Callisto in the early evening.
Image of Jupiter + Moons made from data captured this morning using Backyard EOS with a Canon EOS 60D mounted on a Skywatcher 200 reflector.Moons from bottom left to top right are: Callisto, Europa, Io and Ganymede. This data capture was ~ 100 minutes after my previous upload; Jupiter's Great red spot and the moons have moved!
