SGL 2021 Challenge 6 - Jupiter


Recommended Posts

Some will say there's a lot of noise, others that Ganymede is all artifact and I'll say I was happy. In the midst of clouds and extreme turbulence, I can't complain. The only thing I wanted was a good night of seeing!
Purist processing without making separate Ganymede. All together at once so as not to be too much trouble.

I've spent much of the past 2 days working through the huge amount of data that I capture of Io's transit of Jupiter on Saurday night into Sunday morning. I've reprocessed the previously posted  image showing Io soon after it completed the transit, plus 3 other sets when Io was in mid transit and just prior to the end of it's transit. The separate images below are dispayed north up, with the annotated, composite image showing the progress of Io, with Jupiter presented south up as is preferred by the BAA.

Hi,

 

Here's one from 15th August 2021, a special event when Ganymede and Europa transit Jupiter, while Io goes behind & emerges from the eastern limb, Callisto has completed it's transit much before.

A glimpse of that special event captured while all of the four Galilean moons were close to Jupiter.

Equipment's used:

8" Skywatcher Flextube Dobsonian

ZWO ASI 178MC, Televue 2.5x Powermate, SvBony UV/IR Filter, EQ Platform

Captured using Sharpcap Pro. Processed in PIPP, ASI3, Registax6.

Thanks!

Clear Skies

I'll post my entry in here from quite possibly the smallest scope used so far

358757786_2021-08-11_JupiterSynthL_RGB-resized.jpg.5d9bcc59db4780136489a0f81c2d7cfc.jpg

 

Celestron C6 @F15(ish), ASI290MM, best 25% of 15000 frames in each colour channel. Synthetic luminance made from 60% red, 30% green, and 10% blue.

Stacked in AS!3, processing in Registax and Startools.

Some amazing images in here - l think they might be conjuring up some aperture fever in me!

Awesome seeing in Salisbury on night of 5-6 September during the Europa shadow transit and Io reappearance.  Amazing views, such a joy to watch celestial dynamics in action.  

That being said, I had to keep on bumping the gain up to compensate for the crud in the air.  Timelapse to follow once my laptop has cooled ...

Jupiter and Ganymede on 22nd August 2021


Hi,

Just finished processing one of the many images I took on the evening of 22nd August 2021 at 23.49pm in the UK.
Although this is quite poor compared to some of the fantastic entries here, I'm pleased to have captured the Red Spot in a "portrait mood" and that I also captured Ganymede  as a distinct small disc !

Some Details :-

Telescope: Intes MK67 Maksutov
Camera: ZWOASi178MC .
Mount: NEQ6 PRO

Actual imaging at telescope done using SharpCap.
x2 Barlow Lens used
4,207 RAW8 frames shot through my ZWOASi178MC., at ROI capture resolution 1040x1040. 

Processing:-
Processed through PIPP,  20% stack of 4,207 frames ran through Autostakkert 3.
Wavelets and colour balance adjusted / tweaked in Registax 6.  
Final touches to image done using Affinity Photo.

Regards to All
Steve

Well.....I thought about it and decided to post my photo.

This is my first ever planetary image in which I chose Jupiter. 

The others here are in a different league but I was pleased with it for a first attempt! 😊

Captured with my StellaLyra 8" Classical Cassegrain and ZWO224MC. Video captured using the ASI Suite. Stacked and tinkered with in Autostakkert and Registax.

 

Thanks,

Jonny

Here's another look at Jupiter, from 9 September 2021. The 2 images are just a few minutes apart with Oval BA nicely seen and Jupiter's fast rotation clearly apparant. Each image comprises the best 1000 frames from 3x60s runs of RGB and 4x60s runs of IR, the IR being applied at 50% opacity when compiling the LRGB images in WinJupos.

Last night I had my best seeing so far this apparition. So with the GRS in transit I went for a long run with the thought that I might get enough for a partial rotation annimation. I managed 4 sets of 3x60s each IR-RGB and processed for best 1000 from each video. The data quality was sufficiently good that using the IR as luminance added little in the way of detail and was at the expense of washing out the natural colours of Jupiter, so I ended up stacking just the RGB, hence intergrated 9000 frames per image. The single image below is from Set 3, which I think was the best of the bunch, being just a tad better than Set 2.

By the time I got through Set 4 and into Set 5 the conditions had deteriorated quite markedly, so that brought the session to an end, before I could capture the complete GRS transit. Nevertheless it was a very good seeion and for completeness, I have also attached below an annotated montage of the 4 images, which nicely shows the rotation of the planet over just under 1 hour.

Jupiter looked so serious that night

here my late entry as I only now got the time to process the data. Below some processing details for the image:

  • 5 time 10,000  frames captured on August 13th, 2021 between 22:02 and 22:15 UTC. Not evenly spaced as recording midpoint times indicate: 22:02, 22:05, 22:10, 22:13, 22:15.
  • Captured with my 125 mm TS APO, a Baader 2.25x Barlow and an ASI 290 MM. Used a Baader R-CCD Filter so this is R-Band only. Captured with FireCapture.
  • Processed each frame set the same way with Planetary System Stacker and used only the best 10% of each frame set for stacking
  • Animation was done in Gimp but no further post-processing, so each frame in the final animation is as it comes out of the processing pipe-line, and its on the original image scale (about 0.3 arcsec/px according to FireCapture)
  • One can nicely see the seeing conditions vary in those 13 mins, as well as the rotation, obviously.

My first season imaging planets with a ZWO astrocam - previous attempts with unmodified SLR!  What a difference!  Quite pleased with these two images.  Its been a steep learning curve with correct collimation, star alignment and getting rid of thermals in the large tube!  

Jupiter with GRS and 3 moons, September 5, 2021, 23:39 UT at 36 degrees. Valencia, Spain.  

Skywatcher 14" GOTO Dobson with a ZWOASI 224MC and Televue 3 x Barlow (focal length 5100).  Used Sharpcap 4 to captured  5mins of SERs at 30 FPS (9270 frames) and stacked 39%  in AS3 and  sharpened in RS6

Lo and Ganymede to the left. Shadow of Ganymede above GRS and Europa is just to the right of GRS. Quite pleased with this for my first planet season with an astrocam. Some detail on GRS and  starting to pick out basic detail on Ganymede. 2021-09-05-2339_2__pipp_lapl4_ap140BASTROBIN.jpg.86ce9be4ddcd727c0acb07ca51e38808.jpg

I decided to create an animation of the images that I collected during the mostly good seeing of 15 Sept 2021. The animation lasts about 5 secs, but covers an elapsed time of approx 1 hour of Jupiter's rotation, with the GRS in transit. Some variation in the seeing is apparant. To create the animation I produced 36 separate RGB images from the separate R-G-B videos captured with my mono ASI290MM camera through the C14.

This is my entry, not as good as some of the fantastic images seen here but pleased with it none the less! I have a 45 minute window each night as it passes between trees and buildings as viewed from my garden and finally got the magic combination of okay weather, visible window and great red spot transit! Taken through a C9.25 at F10 on a ASI 290mm, best 45% of 10000 frames at 100fps. Moon to the left is Io.

The challenge has now closed.  Some exceptional entries with some tricky choices for the judges.  The results will be announced within the next couple of weeks (hopefully!)

Concealment of Io - THE IO VOLCANISM
Four centuries after Galileo Galilei was amazed to discover four moons around Jupiter, space probes and powerful telescopes have allowed us to learn facts that would never have crossed the Italian astronomer's mind, such as the volcanic surface of Io or the subterranean oceans of Europa, Ganymede and Callisto hidden under icing. Two new missions from the European Space Agency (ESA) and NASA promise to uncover more surprises about Jupiter's moons in the next decade.
Jupiter's nearest moon, Io, at a distance of about 422,000 kilometers, is the most active body in the solar system. The cause of this geological activity is the heat created by the gravitational pull it feels when it is between the planet and the other large moons - Europa and Ganymede.
“Eruption plumes were observed by Voyager 1 , Galileo spacecraft and New Horizons . NASA's Galileo spacecraft also observed surface lava flows,” said Emma Marcucci, researcher and science communicator at the Space Telescope Science Institute (USA), in a conversation with OpenMind
Io's permanent volcanic activity prevents the formation of craters and gives them striking colors. Ground-based telescopes have revealed that its atmosphere fluctuates when orbit puts it in the planet's shadow. This thin layer, composed mostly of carbon dioxide emitted by volcanoes, collapses when eclipsed by the gas giant, but is restored once more when the moon receives sunlight.
