Here's the first part of a colour image, so far only the red channel is finished...

cheers, Bird

Looking good Anthony,

Was out at Kinchega National Park last night and the seeing was excellent, I should have stayed home to to image Jup.

Looking forward to the colour version of this image, I am sure it will be a stunner.

Regards
Trevor

Very nice Bird!
I was looking at you discovery today against one that HST had taken. It really is breath taking images that you are producing with the telescope.
Well done
Ian

Oh!! I can already tell this will be good! Thanks for the effort mate.

I'm still telling everyone I know, that knows about the impact (or even those whom didn't) of your initial post, after your first conclusions. That first post here, should be framed or something... Did you "post" here first or CN?

Here's a closeup of the impact site, this is straight out of Astra Image after deconvolution. The original data was upsampled 3x before feeding through registax. Red channel only.

cheers, Bird

Looks very nice Anthony. The seeing conditions must have been excellent.

Looking forward to the colour version. :thumbsup:

The seeing was excellent for a while until about 1am and then it went south very quickly.

Wow, looking very good. The seeing for me (on that night) started out ok and went bad when the impact site came into view.

Thanks Anthony – the impact scar seems to be quite elongated now compared to your discovery image.

Cheers

Nice work Anthony, lovely image. You've been fortunate to have good seeing at the crucial times!

What a beauty Anthony and just how well resolved is the scar.
I really look forward to the images that you post, this one must rate right up there as one of your very best.

Stunning work
Regards

Yes, like the others have said, that's another super image Anthony! Great work. It will be very interesting to see how long the scar remains!

Cheers,
Stephen

Seems to be pretty much neck and neck between you and NASA, at the moment, Anthony. I prefer your images, actually. Besides, those cheaters don't have to contend with an atmosphere. Funny how you seem to be justifying Hubble's existence... I reckon your images could be used to mount a compelling argument that NASA should be redirecting some more of their budget to the amateur astrophotography community.
Congratulations.

Great image Anthony. Definately elongated now.

You've been so lucky with your seeing!
Exquisite detail!

If only it didn't take about 4 hours to process each image... why oh why is registax not multi-threaded :-(

Great image, Great seeing conditions,Great work, Everyone around me is asking what happened to Jupiter,At least i can tell them.

Cheers Kev.

I usually have at least three copies of Registax processing different SER or AVI files.

World class images.

I have a question. Jupiter is a gas giant so it is made out of various gases. So if something hits it, then that object is ploughing through various layers of gas until it gets low enough in Jupiters atmosphere that it hits liquid compressed gas? Like hitting Earth's oceans.

Jupiter has no rocky part right?

Its surprising then that the scar lasts as long as it has.

Greg.

Should be roughly the same as the SL9 event in1994,

Congrats mate. We have of course spoken while I was in China, but this is my first chance to congratulate you on the forums. Excellent discovery.

You're right there, Greg. Up to a point.....unless it was something very large (like >100km in size), an impacting body wouldn't get far enough down into Jupiter's atmosphere to hit the liquid body of the planet. The atmosphere is too thick (>1000km). Bodies the size of the largest impactor of SL9 (1-1.5km) would plough down probably 80-100kms, down to where the pressure was around x10 Earth normal. That would put it at the base of the cloud layers...just below the water clouds. It wouldn't go much further as the stress overloads on the structure of the impactor would exceed the strength of the materials it was made out of.

Even a 100km sized chunk of flotsam would have trouble getting down to the body of the planet as the pressure at the atmopshere/liquid body interface gets awfully high....around 1 million atmopsheres!!!. It'd be like plowing through ultradense treacle.

It would be interesting if you could grab images from each night and select a region around the impact and morph the image from one day to the next, this would show the gradual dispersion of the impact through the atmosphere. Interesting experiment to think about...
