Jupiter - April 2 - Canberra

[matt]

What a fabulous night/morning!!!

Set up out at Bird's new place out at Murrumbateman late yesterday afternoon and then drove back out at 2.30am this morning.

The seeing was stunning at times. Easy 8.5/10.

Captured 35 AVIs. This is the result of picking one at random from that batch and giving it a quick run through RegiStax4.

There's detail everywhere! I am really happy with the data I collected. I'll definitely be giving it more thorough and careful processing in AstraImage and PS.

The subtle detail in the festoons and tiny red dots along the SEB around the GRS is very pleasing. The detail in and around the GRS is also noticeable compared to the data I collect when imaging "in town".

I'll try and find the best when I've got time to go through them all

Can't wait to see what Bird's gonna produce.

Excellent work Matt, can't wait to see the result of the rest of these (and Bird's!!! )

Very saturated colours on this one, which is nice. However maybe you've gone a bit too far on the gamma/curves reduction.. the setting limb is perhaps a bit too dark for me.. but maybe that's just me. I know it was a quick process so I'll wait for the final

Congrats, can't wait to see more!

Very nice image Matt! Just got home, have to copy all the data off the laptop in case I go back out tonight, captured 110Gb last night :-)

cheers, Bird

Mike

Appreciate the comments.

Here's a different one I produced on the run while I was out at Bird's, which had less gamma and less saturation.

Also a little gentler on the wavelets.

It's not quite as sharp.

I don't seem to be able to shake those rings, which is why I used a little more gamma to try and hide 'em at the limb

[iceman (Mike)]

yeh I see what you mean. Are these resampled 150%?

I can't wait to see your animation.. I'll be on the lookout for "yippee man".

I only captured 7 avi's this morning.. should help me get some real work today as well

Thanks, mate!

Like I said when I was out there, I'm so excited with the conditions we had I'm going to post something real quick, even if the processing is a little rough and ready

If these are what I can get out of the data spending only 10 minutes on processing, the results with a more careful approach should be very nice.

I know there's no way you'll rush an image onto the website, so I won't ask

Take your time

[bird (Anthony Wesley)]

problem is... I've captured about 300Gb in the last week, I'm having trouble finding places to store it, and it just takes sooo long to copy aorund...

Yep.

Mitchell 1.5x resamples at Optimise stage in Regi.

I was chatting with Bird this morning about a workaround on this prob.

I think the resample is definitely not doing me any favours.

[bird (Anthony Wesley)]

Matt, I'd suggest splitting the avi into individual files with virtualdub and then processing each colour individually, then recombining.

This would certainly get the most out of your data, and I think mike has a tutorial on this around here somewhere (don't you Iceman?)

ps looking through some data now while copying, goodness me, Hubble has some competition :-)

Bird

[iceman (Mike)]

Wow Anthony, can't wait to see it.

And yep, I've done the split tutorial - Matt knows about it and how to do it. I'm sure he'll take the extra time required to do it with this great data.

[Ric]

Great shot Matt, the GRS really stands out fantastically.

Cheers

lovely image matt,

ok, testing a theory time.......were you able to compare the shape of jupiter whilst bird was capturing with a perfectly cooled mirror as opposed to yours maybe not being ambient.....ie was your joop moving in terms of shape??

as we discussed the other day on the phone?

[matt]

Thanks Dave

No... for the most part my Jupiter's looked quite stable and similar to Bird's, although it's hard to compare when we're using different aperture scopes, different types of scope, different cameras, different capture software and hardware ie filters etc.

I do know the Jupiter's in my earlier AVIs were more stable. I've yet to get to those.

[davidpretorius]

cool, did bird look at your gamma settings?

[matt]

Yes he did.

They seemed fine. Only had them set around the 10-15% mark (gamma).

Here's another AVI given a quick run through R4. Only this time, no Mitchell (1.5x) resample.

Smaller scale but processing artifacts less evident.

I'm now working through all 35 AVIs to find what looks like the best.

Then its Virtualdub, PPMCentre, RGB split, separate RGB process in Regi4, RGB recombine in AstraImage, final tweak in PS.

Hmm... when to resample for larger image scale

[davidpretorius]

i would manually do it with ninox (the new ppmcentre)...bird is close to an interface (gui), but upscale = 3/2

maybe give it a try on the previous one where you did a mitchell resample and compare results.

mike from memory was comparing the three ways of upsizing on his great data from a few weeks back.

not sure of the juries decision?

[matt]

Is it possible to do that 3/2 upscale in the current version of ppmcentre (PCFE)?

If not, I'm stuffed. I am a computer luddite

[davidpretorius]

the PCFE thing that hitchhiker wrote does not use this option.

otherwise, it is the good old command line

do you want to send one of your avis to me? burn to cd and post.

I will test ninox versus mitchell with some decent data
