If you use a diagonal you get a mirror image swapped left-to-right.

David was suggesting your image was flipped vertically (top-bottom), which wouldn't even switch the moons around.

I never use a diagonal to image the planets or DSO imaging. Too much glass interfering with the light path.

One of my better images of Jupiter this year, captured last night (July 9, 05:52 UT) while I waited for Saturn's opposition.  WinJUPOS saved the day here, as seeing was average, and single stacks didn't look that good - this is a combination of three stacked and sharpened images.

That is a good image for any location, not many process modest data as well, your work with Winjupos really stacks up!

Jupiter up at 38° over the horizon from july 9.
Gear used: Orion Skyquest XT6 (manually guided), Neximage 5 camera, XCel LX 2X Barlow, captured in iCap 2.3 with histogram at 25%, processed in Autostakkert!3, Registax 6 and Photoshop CS6.
 
The seeing that night was very good, I even could see details visually on the planet's disk using my 2.3 mm eyepiece (almost 500X) before deciding to record some videos. Too bad clouds rolled in 10 minutes later.

Super work my friend, and I believe it may be your best image of the apparition. WinJUPOS is an amazing tool...

Hi All,

 

My very first image of Jupiter and post on CN smile.gif.
I have no experience yet with proper image processing and am complete beginner in astrophotography but am happy with this first result.

Equipment: Takahashi FC-76DS, FC-76 Flattener, ZWO-ASI 385MC

Processing: PIPP and Registax

Hi cornelis, welcome aboard! Congratulations on your first CN image, it looks very much like the view in an eye piece before clicking the link. Your image is sharp and shows some nice surface detail including the GRS, great work capturing the shadow transit in progress (and Ganymede is also visible off to the right) smile.png  Next time out you might want to try a more powerful Barlow lens or Powermate in your imaging train to enlarge the image scale if the seeing permits, that will make it easier to see the surface detail. Good luck, I look forward to seeing your next images waytogo.gif

I would encourage you to use AutoStakkert instead of RegiStax for stacking. After stacking with AutoStakkert you end up with a 16 bit tif. You can then open that file using RegiStax and continue with wavelet processing.

 

You can download AutoStakkert here and quickly learn how to use it here.

I totally endorse using AutoStakkert, it is the best stacking solution available while RegiStax wavelets is the tool of choice.

Thanks for the kind comments, Foc and Brian.  While I'm not getting the sharp images I got two years ago when Jupiter was at 37° instead of 20°, it's still satisfying to be able to produce decent images on better nights despite the sub-optimal conditions.  We're very fortunate that so many people have invested their time into creating the excellent software and hardware (especially ADCs) that make this possible.

Many thanks BKBrown, WarmWeatherGuy for your encouraging comments and advice.

I did another run last night using a 2x Powermate and processed the image in AutoStakkert as you suggested and it definitely improved the final result imo.

Unfortunately no GRS and moon shadows this time.

Thanks a lot, i am definitely hooked now grin.gif

This opposition time around, there are not many transit events with the moons. I have the Sky&Tel Jupiter's Moon app on my iPad, and each and every night for my time zone, I do not see any moon transits. All I see is the occasional GRS transit.

Sky & Telescope has a .pdf listing all events for the year 2019 here. To get to it go to skyandtelescope.com and click on Interactive Tools under Observing. Then click on A Jupiter Almanac.

Surely Io, Europa and Ganymede transit as often as they do any other year.  They each still have to pass in front of Jupiter once every orbit.

Hello Guys,

 

Here is my jupiter images from june 29, and june 30, under average seeing conditions.

 

Hope you like it !

 

Clear skies!!

You've got some really good data there, Willian.  I wonder if you've tried doing a colour balance, something you can do in Registax, but which can come out better in programs like Photoshop.  The images are nicely detailed, but look a little gloomy.  This is all a matter of taste of course, and what you've got is fine, but here's what I get from your image with "Auto Color" in Photoshop, and a little increase in saturation.

Thin, high cloud and the nearby Moon dimmed Jupiter a little and led to the colours being washed out in the resulting image.  However, despite a poor seeing forecast, the view in the eyepiece and onscreen was steady, with details like the dark spots in the northern temperate region being visible in the eyepiece.

KiwiRay,

 

That's a couple of nice images back-to-back, I particularly like the latest shot. If you get the chance, it would be great if you could share your processing steps for our colleagues on this thread. I have been a long time fan of your color control and efforts to minimize noise...

Thanks, Brian.  I'd be happy to post some details of my process - will work on that soon.

 

Just a note of clarification, that post #1794 is Willian's very fine image - I just adjusted the colour to show another way of presenting the image.

Hi guys,

   Here's an animation of 6 frames that I took while waiting for Saturn to clear my roof. (Photo is in small bore challenge for Saturn). The moon that is shown is Io. Photo taken on 12 Jul 2019, 6 frames taken from 22:55:09 to 23:13:53. Equipment is: ETX125 + 2x Barlow + ZWO ASI120MC.

Looking at Io, I think I need an ADC. The atmospheric dispersion is clearly seen.

Very cool…I did the same thing waiting for Jupiter, but I captured Omega Centauri through my C5 instead!

 

You can fix the dispersion by simply aligning the red and blue channels to the green channel. I've heard it claimed that Registax does this automatically. I just do it in Photoshop. Just move your red channel up two pixels and your blue channel down three, and Io is whole again. Jupiter will also benefit.

Thanks for the info. I'll try it out.
