Jupiter 23rd Oct.

[asimov]

Well as you can see, the seeing was pretty nice tonight...:)

Let me know how it looks, still not sure if this new monitor is calibrated..Thanks.

C11/DBK

[Lester]

Looks very good to me. Good on ya John.

[Shiraz]

Beauty John. looks spot on to me.

[asimov]

Thanks for the confirmation guys.

Another one from earlier in the evening. Not as good seeing wise as that first one posted, but I'll take it.

[Paul Haese]

That first image is superb John. Certainly one of your best images. Great detail.

[The_Cat]

Hello Paul.

Jeremy.

[mswhin63]

Great images John, nice to get good seeing.

[asimov]

I find it somewhat unethical to come in my thread & say hello to Paul, & completely ignore why this thread is here. Saying hello to Paul is fine, don't get me wrong.

Have a bit of respect.

Thanks to all the rest:thumbsup:

[Matt Wastell]

That is a cracker John!
The colours look good on my screen and the detail is great!
Well done on this image!

[asimov]

Thanks Matt. I think I have another good night coming tonight, but we'll see. The great seeing has been very close to me; withing a few km. according to a few maps I've been looking at. I'm right on the coast, within 350M of the ocean & what happens is all 3 layers are travelling east & as soon as they hit the coast line, they chuck a 90 degree lefty & head up the coast line, obviously creating turbulence. You can see it on the live feed happening. This takes place right on top of me obviously, so I'm a bit peeved man!

I should head west a few K's me thinks..

[sasup]

Did you take this shot with your 8"? I ask cuss I was getting nothing like it on my 12" on the 23

[Quark]

Very nice detail in your first image John, looks just great.

As you have mentioned the seeing for the 2nd image was not as good but I prefer the processing of it better with regard to how dark the limb is in the first image.

This is a very subject thing but I think your first image would look even better if the limb was not so dark.

Cheers
Trevor

[asimov]

Thanks Trevor. Yes, I can't seem to callibrate my 2 monitors so they are the same. I can get close, but not exact. I see the dark limb on my old computer but not on the ASUS..

[asimov]

The 'C11/DBK' in your quote refers to Celestron 11" SCT - DBK = the camera. You could live 1KM from me & you'd probably get nothing like I got either. It's all seeing condition related.

[Irish stargazer]

They are stunning images John.:thumbsup:
I am going to have another go this evening althought I don't think the seeing will be as good.
I have been to one of Damian Peach's lectures on planetary imaging and he mentions to be successful requires careful preparation, good optics, perfect collimation, thermal equilibrium, but above all- good local seeing. You seem to be blessed where you are.

[asimov]

Thanks John. Yes, everything you mentioned must fall into place before good results can be had. The last 2 years here in Bundaberg has been terrible, but this year has been a different story.

Thanks again.

[asimov]

Lucky last! From very close to the same time as the first one posted. I forgot to rotate the first two, but remembered to do it on this one.

[Clayton]

I have been away for the weekend, and missed this.
Great images. I think the first is the best, closely followed by the third.
Nice to see you get some luck with the seeing (more likely, being out when it presented) and nice job with the processing.

[John Hothersall]

That is a stunning image John, its waiting for that lull in the seeing and snatching a detailed image, hope the lulls come my way.

John.

[michaellxv]

Beautiful images John. I think I like the 3rd one best, the colours look more even across the whole planet. The 1st one is great for detail too.

[asimov]

Thanks guys. I still have more to process but I can't see any of them beating #1 and 3.

[lcd1080]

Wow John, to my eye this is your single best effort at imaging Jupiter to date; it looks like you're making excellent use of your new Astronomik RGB filters with the DMK. I especially like the detail in the white area surrounding the GRS and in the swirl formations within the NEB.

[asimov]

Thanks mate but no, this was done using the one colour shot DBK;)

[Irish stargazer]

John

How many frames do you take and how many do you stack?
I have exactly the same scope and camera as you and my attempts don't even come close to this level of image (but I'm working on it!)

[asimov]

Hi John.

On average I acquire between 4000 - 4300 frames @ 30FPS.

As to how many I stack, that depends on the seeing. I always work with 'lowest quality' of 98% in registax. If the seeing is great it'll want to stack at least 3/4 of the frames but in average seeing it'll only want to stack a few hundred.

[midnight]

John,

Superb :thumbsup:- esp for that DBK. Just goes to show the major effect of atmospheric turbulence.

Since borrowing a 5x Powermate, it's now becoming pretty obvious the sudden changes in quality due to turbulance that I couldn't really see b4.

Now you've got to this quality level, is RGB imaging a possibility in the near future;)???

BTW I like image 1 - fantastic detail in there:thumbsup:

Thanks for sharing.

Darrin...

[asimov]

G'day Darrin, & thanks for that.

To be honest, I have seen no real advantage in RGB imaging over colour one shot in average seeing. I'm only talking mono DMK versus the colour DBK here of course.

I haven't had any outstanding seeing where I am & I don't expect to either. Once you've studied laminar flows; 3 layer air flows, jet interaction & what happens to seeing if you are living on the east coast of a land mass, you begin to realize a few things.

RGB imaging will come into it's own, but not on Jupiter this apparition for me.
