Jupiter with Galilean moons Europa (with shadow) and Io

Here is an image of Jupiter with Galilean moons Europa (with shadow) and Io in attendance taken on 10th Feb 2018. Ganymede was just out of frame to the right. Generally, the seeing was quite good with some light cloud around.

Taken with a Tak Mewlon 210 F11.5, TeleVue Powermate x2.0, ZWO ASI 120MM-S and Starlight Xpress USB FW.

The image is made up of 30 sec R, G and B AVIs and is my first time using RGB filters in planetary imaging. I havenít quite got the moons lined, up so there is a little colour fringing visible.

Processed in AS2!, Registax (Wavelets), CCDStack (Align, RGB) and PS CC.

Cheers

Dennis

Wow, well done! Couldnt hope for a much better result! I often have trouble with moons . I've found if you want nice moons you almost have to re process just concentrating on lining the moons up, or you can tweak them in paint shop to even out the fringing. Really top notch image you've made there. I'd print it and stick it on the fridge!

Thanks Dave, I appreciate you stopping by and taking a look, its been a while since I got the rig out.

I actually set up for the evening just to test out a newly acquired USB to RS232 Adapter (c/o the good folks at Wildcard Innovations) on the EM200 Temma II mount and ended up going through the night.

Cheers

Dennis

Thanks Leigh, I appreciate your comments and thanks for the tips.

I had been previously used to the venerable ToUcam and colour DBK cameras on Jupiter, so this was my first sortie into the world of RGB imaging. I was reminded how fast this planet rotates so I had to trim my AVIís back to 30 secs duration even though I was only recording at an efl of 4800mm, which is not much for planetary imaging these days.

Took me a while to get my head around the processing and Iíll remember to align on the moons next time and blend them in.

Cheers

Dennis

Have you posted this one in PVOL? You've got good detail of the STB ghost and oval BA interaction there, which they were asking for images of recently.

Was going to say the same as Leigh, if you can put it on PVOL it will be a useful contribution because of the disturbance, also the ALPO Japan Jupiter section too. Really great image, one minor suggestion on zooming in would be to try a despeckle or similar in photoshop or whatever. With any luck that won't cost you any detail, but remove the speckling of the pixels when you zoom in close. Obviously if it appears to degrade the image, ignore me!

Thanks Leigh and Andy, I appreciate your comments and suggestions and will follow up the topic.

I have been out of the game for a while so Iím not across the latest developments re planetary happenings.

Suffice to say that I was a little overwhelmed at just getting my head around the current knowledge base for the capture and processing of RGB files for Jupiter with all the new beaut software and processes since my ToUcam and DBK days of yonder past.

I have 12 sets of RGB data which I have just converted into a nice animation which I am very pleased with. How good is AS2!, Registax, CCDStack and PS CC, not to mention a little good luck with the seeing.

Cheers

Dennis

Okay, received my registration acceptance from the folks at PVOL but when I tried to upload the images, I received an authorisation error so could not continue.

I found an e-mail address so I sent the images via e-mail instead.

As I was becoming familiar with the PVOL site, I saw some amazingly impressive images there; mine are quite diminutive in comparison...

Here are a few of them (8 from 12).

Cheers

Dennis

Hi Dave

Thanks for your comments, I appreciate them.

I managed to upload an animation to the PVOL site and here is a link that hopefully works - it worked for me!

Jupiter Europa Io Animation

Filesize is around 600KB.

Cheers

It was good to dip my toes back into the planetary imaging waters again, although much has changed and the images of today's planetary astro-photographers are astounding in their size, detail and quality.

Cheers

Lovely images Dennis..how the Planetary images here are getting even better year by year..

From memory, theres a GANYMEDE Transit on 4th March at 1.32 AEST at a reasonable altitude of 33į...Should be a cracker !
I know I'll be watching.

Thanks Trevor, I appreciate your comments.

I was shocked not only by what I had forgotten since my last efforts, but also inspired by how rapidly advanced planetary imaging has evolved.

Cheers

Dennis
