Taken the morning of 06/29/19 with ASI224 and x2 barlow through an AT6RC. Was lucky I stayed on Jupiter long enough to catch Europa's shadow. I hadn't looked up info on that so didn't know that was going to happen and got a pleasant surprise on getting that.

 

9,000 frames out of 19,482. Stacked in AutoStakkert 3, wavelets in Registax 6, deconvolution, curves, color saturation in PixInsight. I had also resampled it larger in PixInsight but over did that, as well as the rotation in there added more background . I did a little final tweaks in Lightroom and cropped it down some as well as sampled it back down some on the export. Likely spend too much time the tweaking it and shouldn't have resampled it larger by that much. Was likely crisper before that but I'm happy with the details I got.

Here are my latest images of Jupiter, for July 1. Transparency was below average and Seeing was average. Warm, Summer night, temps around 65 *F.

 

Nexstar 6SE, alt-az configuration, Neximage 5 camera, Toshiba laptop with iCap 2.3 post processing Autostakkert!3 and Registax 6.

 

19 gain and 1/44 second exposure, best 10% of 5555 frames.

Still getting the hang out of processing.

 

Jupiter up at 41° over the horizon from last saturday. Nothing special but quite a good seeing it was.

 

Gear used: Orion Skyquest XT6 (manually guided), Neximage 5 camera, XCel LX 2X Barlow, iCap 2.3 at Gain: 30 and Exp: 1/120 s. 

25% of 2,800 frames processed in Autostakkert!3, Registax 6 and Photoshop. 

 

Quick question for the more knowledgeable ones in here: when I use a Bahtinov mask, I normally try to reach focus by looking into my laptop's screen when the ROI is a large one (1080p resolution). Do I need to reduce the ROI into the size I will be recording the video and reach focus there in order to have almost perfect focus?

My very first GIF of Jupiter.  Images taken on 7/1/19 between 11:05pm & 11:18pm EST.  

Equipment - Skywatcher Skymax 127mm, Orion Sirius, Tele Vue 2x Barlow, Canon T3i, BYEOS, Autostakkert 3, Registax.

I took 7 videos, each of 1,000 exposures and stacked the best 80% of each, wavelets and created a GIF from the sequenced images.  I just got a ZWO ADC and I'm in the process of adding an ASI224MC... looking forward to improving on this with a faster frame rate!

Iowa appears from behind Jupiter on July 2 and transits and departs on July 3

- Jupiter over  two nights  2nd (first image) and 3rd July (next two images)  Celestron C6 ASI1224mc Powermate 2.5x.  

 

Not particulary good seeing on either night (and at times a neighbours chimney or a gas heated roof might worsen it). Was up to after midnight on 2nd July for the GRS and have yet to look at all the captures. Initial conditions were not good on the 3rd, but after a quick dinner found Jupiter had steadied somewhat. Was keenly hoping to capture the appoach and transit of Ganymede on July 3 but alas heavy cloud came in around 8.30pm local time (10.30am UT) and I gave up on waiting for a chance on Ganymede at midnight as had work the next day.  Nevertheless I feel I captured a bit of detail and can be happy with my efforts.

 

Edit...Thanks Ray for pointing out that Iowa has not joined Jupiter and its moons.  Seems a bit a sleep deprived thinking on my part put the USA a bit too far ahead in the space race!

Very nice, indeed Foc - the third image is particularly clear.  It's nice to be reminded of what Jupiter can look like in a 6" scope, as I'm not getting views like this from Seattle this year.

 

But "Iowa"?!  Was its appearance quickly followed by that of little known Jovian moon, Nebraska?

Do I need to reduce the ROI into the size I will be recording the video and reach focus there in order to have almost perfect focus?

For planetary work, just focus on the planet's surface (Jupiter or the moon or whatever), don't use a Bahtinov mask. If you can't focus directly on the planet then the seeing is likely not good enough to image anyway. That said, if you are doing a low magnification image of Jupiter so that you can capture a wide field with all of the moons then perhaps you should use a Bahtinov mask since the image of Jupiter could be very small.

You can also focus on one of the moons. If the moon image is wavering, jumping in and out of focus, then the seeing is too unsteady, otherwise try to get a good focus of the moon before imaging. That usually helps. I usually focus on a star before going to Jupiter but for now on, I will try either the surface or a moon to get my focus. Since I live at 42* north latitude, Jupiter is only about 20-30* above the horizon and in not a great spot for imaging due to atmospheric refraction.

Hi guys,

   Another rendition of Jupiter again with my ETX125, 1.5x Barlow and ZWO120MC. Finally got the Great Red Spot this year smile.gif I caught Ganymede when it was just about to disappear behind Jupiter. I decided to do a wide view so that my photos catch Io and Callisto as well. 17 photos were taken on 06 Jul 2019 between 22:06:11 to 22:45:43.

  

  Seeing and transparency wasn't too great, but was good enough to get these images.

 

Jupiter_reduced.gif

 

Unfortunately, I had to reduce to size to < 500 kB so it's a little small. The next post shows the still before Ganymede disappears.

And here's the followup from my previous post: A photo of Ganymede before it disappears behind Jupiter.

I think my focusing is still a tad bit off despite having pre focused on Io using Sharpcap focus  aid.

I just thought I'd add a pic to the small bore challenge.  This is actually from my first time using an astro camera and its associated software.  I was expecting a space potato, and was very happy with the results! 

 

I have a question...   Although very faint, there appears to be a moon on each side of Jupiter, and after cleaning things up a bit Registax, it looks like there is another moon transiting.  How can I tell which moons are (barely) visible here?  This capture was taken at 12:34am CDT on 6/22/19.

 

jup_003455_lapl4_ap34_rotated_cropped.jpg

 

Also, when wavelet processing an image of Jupiter and its moons in Registax, do you (can you?) process the moons differently than Jupiter itself?  Or do most people just process the image as a whole?  I'm still climbing the steep learning curve  smile.gif

 

 

Thanks!

You can get the moons and the planet with the same settings. Here is an animation showing what I got a while ago.

 

Here is a picture I got using WinJupos with the date and time you gave.

Here is an annotated version of your picture showing which moons are which. The app I used is the Jupiter's Moons app from Sky & Telescope website. I believe is it downloadable on iTunes only. I do not know if they made an app for Android. You can also try an Apple app called Gas Giants as well.

 

Jupiter Transit.jpg

 

Registax only lets you process the moons together with Jupiter. However, it may be possible to do them separately with Pixinsight or Photoshop, by creating separate layers of the moons themselves and processing them separately and then re-joining them to the main picture.

Fluke:  Regarding processing of the moons, sometimes I'll brighten up the darker ones (Ganymede, Callisto) in Photoshop, but usually they come out OK without extra work.  For small scopes, Europa and Io often blend in with Jupiter's clouds when transiting, so can be hard to find, which is why Europa itself isn't visible in your image. 

 

Warmweatherguy has the correct labels above, while Stargazer3236 has Io's and Ganymede's labels switched.  After a while, you'll recognise which is which, especially now with Jupiter and the plane of the moons' orbits tilted about 3°.  Except for when they change direction at greatest elongation, you can draw an imaginary line from the moon to Jupiter to identify them: Io is closest to Jupiter's equator, then Europa, Ganymede and Callisto.  Callisto is the only one at present that isn't transiting the planet, so your imaginary line will pass over or under Jupiter.

WarmWeatherGuy, Stargazer, and KiwiRay, Thanks for the info and pictures.  I'll check out WinJupos when I get the chance.

 

Following Stargazer's recommendation, I checked Google Play and found a few apps there that should assist me with identifying these moons in the future.

 

WarmWeatherGuy- Great job on that animation!

IMO, the online Jupiter Viewer utility is probably one of the better references for showing the locations of Jupiter's moons. It requires several inputs to generate its output, but the accuracy is probably unparalleled (particularly for the minor moons, which some utilities get wrong). Below is an example of its output for Fluke's Nexstar image (reduced somewhat in size to conform to the CN posting limits). Also, the links to both Jupiter Viewer and Saturn Viewer (both are free web services):

 

  https://pds-rings.se...iewer2_jup.html

 

  https://pds-rings.se...iewer2_sat.html

 

Note, you probably aren't going to be able to image or see the moon Almathea, but it's the next brightest of Jupiter's inner moons. Well, you can image Almathea, I've done it with a five inch refractor, but it's not particularly easy. The link to my Almathea image also has information on additional resources for locating Jupiter's minor moons.

With regards to my pic compared to WarmWeatherGuy's annotated image, my image is the same as WarmWeatherGuy's. If you notice the orientation of the GRS, you will see that if you flip mine in the vertical, my annotation will match WWG's image too. In my image, based on the Sky&Tel app, Jupiter's Moons, the GRS is located at the bottom of the planet, while WWG's GRS is located at the top. Essentially, both pics are correct, just the orientation of my pic vs WWG's is just different. Therefore, my pic is correct!

Not a big deal, but the orientation of Steve's and your labelled images is the same (the GRS is in the same location - it's not at the top in Steve's).  You've switched the labels on Ganymede and Io.  See also James' image above, which is also north-up.  If your app mis-labelled the moons, then that's a bit concerning.
