Jupiter 17 September 2009 good seeing

[Paul Haese]

Seeing was pretty reasonable tonight. Probably peaking near 7.5/10 but average somewhere between 6.5 and 7/10.

This is the first image I have processed from a lot of data I captured. I missed most of the GRS because of the tree in my neighbours yard (when will it die?).

Of interest is two moons very close to the planet. Ganymede on the left is well recognised but in the cloud tops to the near right limb Europa can be seen. Some interesting detail can be seen in the NEB. Lots of rifting and some ovals forming.

Lovely image Paul,

Glad you finally got some descent seeing, you have captured some very delicate detail, a truly lovely job on the NEB, some nice detail with Ganymede as well.

After looking at Damian's latest effort from Barbados I reckon it is time for us Aussie imagers to get some runs on the board while Jupiter is still so well positioned for us.


I have just come up from my observatory and have started processing, I have an image very similar to this one from early in the night. The seeing here was very good early and just got better through the night.

Regards
Trevor

As usual, a great image, Paul. Something I aspire to. Is that a bit of surface details on Ganymede?

I planned to do some imaging at this time also, but.. well you know... Melbourne weather.. :rolleyes:

A beautiful image. Its amazing what is being done now that if you had said 5 years ago this is what amateurs could do, they would have scoffed. Really nice processing to bring out subtle detail.

That's a good image, Paul.

The processing is very nice. The moons show a lot of restraint in terms of their processing. No burn out! Especially when it comes to Europa, which is close to the limb and that always presents a challenge due to brightness/contrast variation with the planet:thumbsup:

[Paul Haese]

Thanks guys.

Trevor, if only. I reckon we need to go to Barbados to have a chance at getting that sort of seeing. Let alone processing. This year has been a bad year locally for seeing, but next year could be better.

Glen that is indeed surface detail on Ganymede. I could see it during capture. Quite a common sight these days. I put it down to the planet being just a bit closer and this allows more pixels to be covered by the disks.

Allan, yes that is truly amazing how things have developed from 5 years ago. Certainly the camera equipment has made a huge difference. Software is now more powerful than ever before too. Certainly makes for fun nights when the seeing is right.

MAAAAAAATE ! Beautifully done:thumbsup:

[Paul Haese]

This one is from a little later.

The seeing was not quite as nice at that point in time.

Ganymede can be seen transiting the cloud tops of Jupiter

Absolutely beautiful work Paul.
Very nice detail in there.

:thumbsup:

[lacad01]

Detail and resolution is fantastic :eyepop:
Well done :thumbsup:

[StephenM]

Wow! That's a great image Paul!

Cheers,
Stephen

[Paul Haese]

The best of the lot so far. I even upsampled it to show a bit more detail. Notice that Europa is three dimensional with a phase shadow.

Beautiful results, Paul. The last one is certainly the pick of the bunch.

Lovely work Paul... excellent images all round.

cheers, Bird

It needs more copper nails or glypho. ;) I need to have some of my trees die, but SWMBO has other ideas.

Nice images.

awesome

Yep like the upsampled version, very nice.
Your point about good data being able to be upsampled is well put.

[Paul Haese]

Ok here is the last two images of the session. The seeing was past its prime by this stage but there is the Bird strike which I have not got a really clean image of yet.

Image two (http://paulhaese.net/17September20091527UT.html)

If you look closely you can see the bird strike which is a dark extended C shape right near the southern pole which is at the bottom of the image.

I don't know Paul, I reckon you have about as good an image of the Wesley impact remnant as is possible, now that it has diluted to such an extent.

I think it shows up better in the first image, only because I am used to relating its position relative to the GRS.

It is so diluted that it is tending to get a bit lost in the limb darkening of the image. I wonder if it would be worthwhile, specifically for this feature, to do a reprocesses to try for a brighter limb, to maybe highlight the impact better?

[matt]

Very nice. I'm enjoying the detail on Ganymede. Dark albedo features and a recurring bright polar-style cap.

Nice work.
