Jupiter Nov 18th in very good seeing.

[Quark]

Hi All,

What a difference a day makes. Nov 17th was clear but the seeing was unusally bad for my area but Nov 18th was a real pearler.

Imaged Jupiter last night in very good seeing. I just knew it would be a good night, earlier in the day I was at my Lawn Bowls Club and the sky was just such a very deep blue. A jet passed overhead at about 30,000ft and the con trail just stayed there for about half an hour without distorting at all.

Have attached 4 RGB & 4 807nm IR images the seeing for the first 3 data sets ( just under 2 hrs) was brilliant and I would estimate it at about 8 to 8.5/10. My final capture, which was at a lower alt over the roof of my neighbors house was not quite as good. I think more the result of heat coming off of the building than a general drop off in the intrinsic seeing level.

Thanks for looking.

Regards
Trevor

They are pearlers alright, Trevor. The weather up here has pretty well crashed for a while. Thanks for sharing.

Hi All,

The first RGB & IR images are incorrectly labeled so I have attached the correct labels here.

Cheers
Trevor

They're fantastic Trevor, well done! Beautiful colours and processing.

It's a shame you didn't get the SEB outbreak.

Well done!

[bird]

Lovely images Trev

cheers, Bird

[Quark]

Thanks Tony, reckon when those periods of crook weather come in its time to drag out all of the old data and start doing repro's.



Thanks very much Mike, the SEB outbreak is available for me tonight, hope its not expecting to much for the seeing from last night to pop up again tonight.

[Alchemy]

Really nice work. Hope you get good seeing again tonight

[SkyViking]

Some spectacular images there, very nicely done. Hopefully you'll be able to catch the new outbreak in good seeing too.
Thanks for sharing.

[Quark]

Thanks very much Bird, with an ounce of luck these conditions might extend over to you, love to see what Nemesis would do with them.



Thanks very much Clive, have my fingers crossed for tonight, my scope is colimated and Peltier is running.

[Quark]

Thanks very much Rolf, certainly look forward to imaging the SEB outbreak in such conditions, would make for some very hi res detail.

[John Hothersall]

A good night and love the 3rd RGB with the 2 red spots and the 3rd IR is wonderful in fact all the IR's show so much detail especially around the poles. Have you ever been tempted to use the IR instead of the red channel, I suppose red is always more detailed and smoother? I hate those stubborn con trails that move longways or not at all!

John.

[mswhin63]

Fantastic detail Trevor, great to see.

[Paul Haese]

Nice mate. I took a look early on and thought the seeing was not that good visually, then the cloud marched in. Hoping for these conditions tonight and tomorrow night.

Goes to show how 700km can make a huge difference.

[michaellxv]

Fabulous stuff Trevor. Hope you get some more conditions like that.

[Matt Wastell]

Stunning! Fantastic work - your best stuff I reckon!

[multiweb]

:eyepop: As said previously terrific stuff Trevor. Some of your best fo sure. :thumbsup:

[Quark]

Thanks very much John, there are 3 red spots in these images, oval BA, the GRS and the LRS in the NNTrZ. Yep, love the IR images but I would never use IR with R or substitute IR for R with Jupiter. My images are used for scientific evaluation and the RGB is a true representaion of the planet, with a synthetic G or R the image might look esthetically better but it is not a true representaion of the planet. There is a program that is used by the professionals that can create false colour from a FIT file but that is mainly used with deep sky images to highlight particular regions within the image. Love seeing contrails that just stay there, means I am in for a bonza night of imaging.




Thanks very much Malcolm.



Thanks very much Paul, I think our geopraphic locations make for considerable differences on a day to day basis, the previous night you made an excellent image but up here the seeing was hopeless. I hope you get good conditions over the weekend and look forward to seeing what you do with it.



Thanks very much Michaell, so do I.



Thanks very much Matt, yep, the excitment levels in my observatory were exceedingly high this night.



Thanks very much Marc, appreciate your comment.

[h0ughy]

fantastic results - some really beautiful work there

[Lester]

Fantastic images Trevor the detail is so well defined. Thanks for the views, as always. I am hoping for a go tonight. All the best.

[Shiraz]

Marvellous images Trevor. Thanks for posting.

[Virgs]

What a fantastic set - must feel good to get so much excellent data in one night.

[[1ponders]]

wow beautiful stuff Trevor. Brilliant work.

[Quark]

Thanks very much David.



Thanks very much Lester, stick with it.



Thanks Ray, hope these conditions stick around for a while.



Thanks Virgs, yep, was pretty stoked with it all.



Thanks very much Paul.

[erick]

Very handsome, Trevor! Thanks for showing us. :thumbsup:

[strongmanmike]

Great shots Trevor, the fith one is excellent :thumbsup:

Mike

[jjjnettie]

gorgeous Trev. Thanks for posting.

[Clayton]

Wow! These are stunning Trevor. Particularly the 3rd one :thumbsup::thumbsup:

[Quark]

Thanks very much Mike, although I rated the seeing the same for each data set at 8 to 8.5/10 I think there was a peak in the seeing for that RGB. I really hesitate to rate the seeing at more than 8.5/10. When I went to Hawaii to observe with the Keck's at 14,000 feet I gained some appreciation of what 10/10 seeing really was, so I consider that here in the remote outback of Australia it is never going to to rate as good as it was at altitude in Hawaii so I think that the best seeing I will ever get would realistically be about 8/10. I think a lot of people rate their seeing based on the best and worst at there specific locations rather than taking a more absolute approach.



Thanks very much Jeanette, it was such an amazing night.



Thanks very much Clayton.

[Paul Haese]

Yeah I have changed my approach to estimating the seeing. Since the bad run of seeing for me anything where the scope can be focused and is not wobbling around like a mad womans custard is good seeing. Anything other than that is just crap. When consistent seeing returns I will go back to the Pickering system.;)

[Quark]

Very well said Paul, when it has been as crook as it has been for most of the year I think it provides a whole new perspective of what is good or poor seeing. It is most interesting how some of our fellow images around the world put out really nice images but rate the seeing as poor, maybe they should get to experience what truly poor ( read crap) seeing actually looks like.

[iceman]

This is now IOTW (http://www.iceinspace.com.au)!

[multiweb]

Well done Trevor. Woke up this morning to see this beautiful shot on the IIS front page and I thought it was a hubble shot ;) :thumbsup:

[DarkRevenge]

Congrats Trevor. That's an incredible shot!

[jenchris]

Impressive and beautiful images, I hope I can do one like that some day.

[Quark]

Thanks very much Mike, this will be my first IOTW and I really do appreciate the honer.



Thanks so much Marc for your most generous comment. Just imagine what sort of results we could achieve if we could build something in the backyard with the same sort of budget as was available for the HST.



Thanks very much Luis.



Thanks very much Jennifer, planetary imaging can be a most satisfying and rewarding pursuit and I would encourage anyone with an interest in it to become actively involved.

[kinetic]

Congrats Trev,

that is one magnificent result. Your imaging is really progressing
every post you make. :thumbsup:
I can't believe the clarity of that colour image. So much detail.
Brilliant, well done getting IOTW...well worthy.

Steve

[Clayton]

More fantastic stuff Trevor.
The third RGB is a beauty IMHO, but they are all very very nice.

[Quark]

Thanks very much Rob.



Thanks very much Steve, the images in my original post were processed much to quickly in an effort to post the same day. I have gone back and done a repro of my best image which I think does the data justice.
Have attached it here. If you blink it with the original reckon you will see quite some difference.

Regards
Trevor

[hotspur]

Gorgeous images!!!,these have beautiful colour,and amazing detail,just so wonderful to see these.

The 'Red Spot' looks like it is getting slightly smaller,also it appears more 'red' in these image,over the last few years,many have called it the 'great oatmeal spot'

Congratulations on this capture:thumbsup:Chris

[strongmanmike]

Oh yeh Trev that's excellent mate, very natural and perfect colours (as far as I can tell :P) plus the limb is seemless. Great repro (my specialty) and now very close to Anthony at Exmouth and Peach for sure :thumbsup:

Mike

[gregbradley]

That is amazing quality. If I got an image like that of Jupiter I'd be stoked.

Greg.

[beren]

Crikey :)....Well done Trevor great to see your efforts rewarded, stunning images mate

[Quark]

Thanks very much Eric, sorry for not replying earlier, I missed your post, must have posted while I was in the process of responding to the previous list of posts. You must drop in if you come up this way, it would be great to catch up again.



Thanks very much Chris.



Thanks very much Mike, very generous comments, reckon its a bit of a statement on the current state of the weather that I had the time to do a repro. Bird suggested resampling by 3x which makes for huge files and many hrs of processing but am giving it a go.



Thanks very much Greg, yep, pretty pleased with this data.



Thanks very much Beren, appreciate your comment.

[Scorpius51]

That's a brilliant image Trevor! The detail and colour are incredible.

Cheers
John

[bird]

Excellent image Trev, as has been said by everyone else... good to see.

cheers, Bird

[Quark]

Thanks very much Bird, have attached the same image again but with the data resampled 3x in ninox as you suggested, processed at 3x and then resized by 50% to get back to 150% of the original. This is first time I have attempted a 3x resample and the first time that I have managed successfully to use multi point alignment in Regi.



Thanks very much John.

[bird]

Thanks Trev, I reckon you've gotta be happy with that result...

cheers, Bird

[Lester]

Now, now Trevor, you better stop that, otherwise space craft will become obsolete. A wonderful image, thanks for the view, and all the best.

[BLiTZWiNG]

Awesome images Trevor!

Now, I know I don't know much about telescopes, but I was under the impression that ~10/12"+ wasn't really much good inside Earths atmosphere, obviously this is not true, can you (or anyone else) tell me why at all?

[Quark]

Thanks Bird.



Thanks Lester.




Before I launch into my reply please be aware that I have nothing against smaller scopes and that my reply is from the perspective of planetary imaging. There are many extremely talented deep sky imagers that use small scopes to great effect producing mouth watering images of many deep sky objects. Often these images are the result of many tens of hours of exposure time. Planetary imaging however, is a different game.

Thanks BIiTZ, there is simply no substitute for aperture, in poor seeing a smaller scope may seem to provide a smaller scale image that is steadier than a larger scope and with more contrast.

In good seeing aperture is king. With smaller scopes the increased contrast that some talk about is simply the result of looking at a bright object through an instrument that has very little light gathering power which means that the sky will be darker. A 10 or 12" scope makes a fine observing instrument and you should not be put off by any claims that they are some how so effected by our atmosphere that they would be less desirable. Go to any star party and the longest line up of people will be at one of the largest scopes on the field.

[mswhin63]

This is really cool, I am going have to learn how to use Ninox, if it can do this I would do wonders for my images.

I am starting to experience some issues with apeture rules. My webcam can handle the vast amount of light coming in. I am in the process making apeture masks. They will be central mask not offset as it mis-aligns the CCD sensor.

Still waiting to buy a Powermate, having financial issues ATM. Need to hold off spending too much (Compulsive buying from adictive AP).

[BLiTZWiNG]

Thanks Trevor!

Now I will definitely keep dreaming of a larger scope (though I need to make a mobile platform for the one I have first, otherwise it's just an office decoration).
