Neximage on death row pulls out finger on Jupiter

[Lester]

Hi Everyone,

Seeing tonight was prity steady although the stars were still twinkling up to about 20 degrees.

All the avis tonight were at 5fps, results were okay.

[Lester]

Here is one with extention tube.

[asimov]

Hmmmm...Very nice mate! Is that your best one?

[asimov]

Hey, is this a meade 14" versus a C9.25 ? Winner gets to use the DFK in scope of choice, hmmmm?? :D

[asimov]

By crikey! Look at that! :scared: Great image scale/details/colour....on second thoughts....:doh:

[Lester]

I know you can beat it Asi.:D

I only processed the images in about 5 minutes, may tweek em one day. Got another stacked that looks passable.

Where are yours, come-on, big cough and spit em out, and none of this 4 hours prossessing cause thats not in the rules.:thumbsup:

[Lester]

This is last one for tonight.

Hows the conditions Asi?

[asimov]

Well....I'll just show you my worst one ok ?? ;)

You have me beat with that image scale mate. I've got a few using the 2X barlow, diagonal & 2 extension tubes, & boy was it hard to capture! :doh: I'm getting that debayer cross-hatch on all of the big ones though & I don't know how to fix that, never come across it before! :shrug:

This one is the first one I captured with the onion I was raving on about earlier.

[Lester]

Very nice Master,

That is very mild onion, I cannot even see it. No doubt you will reheat some left overs from tonight and serve them tomorrow, I'd say while you are breathing you are a chance.

Trouble with cross hatch! Perhaps you want to buy a neximage, it would love to go to such a caring owner as you. Only time I had trouble with cross hatch was when I tried to capture at 30 fps.

I thought the seeing was gradually getting worse at 11:30 have you check it since?

[asimov]

Yep. It's worse. I gave up on Jupe awhile back. Getting too low.

[asimov]

Now heres a question. How would you rate the seeing? 5-6/10?

[Lester]

Now Now I am not falling for that trick! You and I both know it was a 4/10.

Okay, perhaps a 6/10 at the best.

Good night.

[asimov]

Night mate.

[iceman]

Wow, great job! Glad you finally got some good seeing. The image scale is huge in he second one.

[Dennis]

Awesome Lester, absolutely awesome! The colour is a little to "rich" or saturated for my delicate palate but that's just a personal taste. Superb detail and image scale.

Well done

Dennis

[Robert_T]

Lester these, especially the second and thirds are so amazingly laden with detail it's hard to begin. Detail upon detail in the red spots and more detail within the central festooning than I dreamt existed. You gotta be proud of these. :thumbsup:

Reckon you could make these even better. In your processing you've cured the "too dark" issue, but the colours here appear overly saturated here and I reckon it's actually obscuring some fine detail.

cheers,

[Lester]

Thanks Mike, Dennis and Robert,

for your kind words of encouragement.

Will be trying to reprocess image, and see what comes out. These were only done in a hurry last night, like I said about 5 minutes max in picture publisher.

Thanks.

[Lester]

Thanks again for your comments and help.:thumbsup:

Here are 2 images from last night, I haven't added any colour saturation during processing and in many cases went to minus saturation. Kept brightness up (Robert=thanks):)

The first has waveletts 6=75 5=50 4=20

the second 6=70 5=36 4=13 3=5

In both cases stacked 300 images from 600 = captured for 120 seconds.

[Robert_T]

Lester they're fantastic:thumbsup: :thumbsup: :thumbsup: , I prefer the lighter wavelets of the second, reckon you could go even lighter on 6. Have you tried just wavelets 1 and 2 (Dennis style), say a 15-20 on 1 and 10 on 2. Might be grainer, but if the seeing is good enough this can really bring out the fine detail.

Looks like GRS and Red jnr aren't going to merge after-all rather pass as ships in the night :D

[Lester]

Thanks for tip on waveletts Robert will try.

[davidpretorius]

Lester these are superb, some of the best on this forum in my opinion.

You have to be wrapped in the detail you have got with the extension. I love it!, now off to check out Asi's

[Lester]

:cool: Thanks Dave,

Hearing such words from you means a lot.:tasdevil:

Yes I am very happy with the results. The scope was still up to 2.5 degrees above ambient, didn't have time to use cooler at all, so goodness knows what could have been. Although its hard for me to emagine.

My thanks must go to Asi, for his hours of showing me the finer points on processing, his eye for detail and subtle changes is far beyond my ability.

:bowdown: :thanks: :thumbsup: :2thumbs:

[Lester]

Just reprocessed the first one from thread 18 with wavletts 1=30 and 2=15

What do you think?

[asimov]

Wow Lester, they are just brilliant! I never would have believed there would actually be a problem with capturing 'too much colour' with a scope on Jupiter. I reckon it's possibly camera related though. Perhaps lowering the saturation at capture time would help ?

Could you tell my the settings you captured with please? Spare no details.

Theres a wealth of detail just waiting to be tweaked out of those AVI's yet ;)

You really do need Astraimage mate! I don't understand why the free version has been taken off the internet! Can anyone help here? Gotta get Lester a copy of this...It's driving me CRAZY! :lol:

[Lester]

Thanks Asi,

The last posted image recipe= 5fps 70% gain 0 gamma 1/10 second exposure 55% saturation 25% brightness

Most of my others were very similar to this except the last where I tried 30% gain 25% gamma 1/5 second exposure 100% saturation 25% brightness and trashed it= full of Onions.

[davidpretorius]

yes asi has that "being an absolute natural" with astronomy!

here is a link to astra image on my website

http://precons.com/iceinspace/gallery/ai25max.zip

[asimov]

Ah...So thats why the dark limb...25% brightness! I keep reading NOT to touch brightness & contrast EVER! I have experimented with brightness I must admit (lowered it to 40%) But now I leave it alone.

[davidpretorius]

happy 5000 old dog of the sea!!!!

[asimov]

Beauty Davo! There ya go Lester! Happy deconvoluting! WOOO-HOOOO!

[asimov]

Oh hell! the big 5000 spam posts! WOOO-HHHH once again! It's all good!!

[davidpretorius]

brightness never lower than 50%, i have been lifting to 55 - 60 lately

[asimov]

Correct Dave. Now thats probably why Lester is getting the over saturated colours ?

[Robert_T]

Thanks for trying those lower wavelets Lester. No, looks like you had it right with your original wavelets, for these anyway - if you do crack an 8+ seeing night give it another go then. Hard to believe you were still 2.5deg from ambient - incredible.

And like the guys say you gotta get Astra Image - you just gotta. :D

Happy 5000th Asi-mate:thumbsup:

[StargazerX1]

Lester,

Don't want to give you a big head or anything, but your second post is close to matching the very best Jupiter image from an amateur based scope I've ever seen. I second Dennis, I think it would benefit greatly by toning back the color. Its scary to think what extensive image processing would bring in such an image! The whorls and other activity in the polar areas is fantastic!

God I wish for such seeing (and elevation, Jupiter will get no higher than about 42 deg from my location). I don't want to wait till 2010, so I guess a trip is called for.

Congrats on an image you can treasure for a long time.

Lester, these images are just fantastic! So much to see in the belts and amazing fine detail even in the festoons.

There's been so much new info for me in this thread about capture and processing settings, some of it very different from what I've been using, especially the low brightness setting. And the zero gamma, isn't that supposed to lead to onion rings? I've never had any success using wavelets 1, 2 or 3 - always seems to increase the grain objectionably.

Going through the processing blahs at the moment. Just too many variables involved and it's hard to pin down cause and effect when you change settings. I can see a (long) period of experimentation coming up.

Anyway, well done - quite inspiring!

Graeme

[Lester]

Thanks Graeme and Glen,

3 months ago I didn't know a thing about imaging Jupiter.

This forum has been fantastic for its guidance in many areas of amateur astronomy. I couldn't have done it so quick without the help of many kind fellow astronomers here. Plus the conditions last night were good, but not an 8/10.

[Lester]

Dave,

thanks for the link to Astro-image; (you will laugh) I copied it into program files, couldn't find it, so restarted computer and still cannot find it. I will wait for Celestine to come home after football to retreive it for me.

Man! I have still got a lot to learn.

[Lester]

Asi, Mate, friend,

Well done on 5000 posts. You are one of the originals of IIS and I know have helped many.

:thanks: :bowdown: :thumbsup:

[Lester]

Hi Graeme,

low gain will encourage onion rings, I have been using mostly 70-80% gain.

I could experiment more with gamma. But visually on the laptop gamma washes out the detail.

I must say what I am doing is not necessarily the best, coz still learning too.

[asimov]

Don't thank me yet mate, I'm frantically trying to kill this debayering problem..If I do I'm gonna wipe your fantastic meade shots off the planet!:P ;)

Just joking mate :D ;) :)

[Lester]

Joking or not Asi,

I know you will fix it and by what you have done with other images, I have seen your potential.

Good luck.

[asimov]

Well, I'm no closer to fixing it than when I first started, I have no idea how to having never come across it/this before. :shrug:

Once I've finished stacking I'll be starting a new thread with these images in it to see if the guys have encounted this before.

[asimov]

Lester, Daves astraimage download is a zip file. You will need winzip to get to stage one.

What say I come out for a visit if your not too busy?

[anthony2302749]

Hi

What a great shot Lester:bowdown: . As per the earlier discussion on which telescope is best for planetary imaging, the Celestron or Meade, I would say from your effort the Meade 14” is equal to the task
