My best Jupiter to date

[moxican]

On the night of Sept 6 I had something rare here... good seeing. I collimated the C9.25 beforehand and just received my 1.75x Siebert barlow. I was imaging for about an hour and then the sun came up. Recorded about 11 avis. Stacked about 25% of each in AS2, drizzled at 1.5x, wavelets in R6, and post process in CS5.

74 fps, gain 50. gamma 50 (default), histogramm 55%.

39 fps, gain 35, hostogramm 58%, gamma 50

50 fps, gain 40, histogramm 54%, gamma 50

And an animation of the images

These are really good, well done !

[baggywrinkle]

Wow, nice work.

[michael.h.f.wilkinson]

Absolutely stunning. Great animation

[Stargazer33]

Very nice images. I can't wait until the old man gets to a descent elevation at a reasonable hour here!

[Atlas]

Great images! Well done.

[JamesF]

Some very nice images there.

Very sweet, lovely collection Well done!

[theo]

Lovely set of images. What camera were you using?

Some nice images there.

I would check R6 isn't doing an auto stretch when you put your stack in to apply wavelets. If you look at the centre of jup, some of the images look a touch over exposed. The autostretch function in my experience always over does it. Even if you put a lowish histo image into R6, it will autostretch it even if you haven't selected that option in the tick box!!!

Keep up the good work.

[WaveSoarer]

Wow.

[moxican]

Thanks for the kind words guys.

Sorry I forgot to post the camera is ASI120MC

About R6, when I load the image into it it asks me if I want it to stretch the intensities and I always pick no. I am not sure if that is what you were talking about Freddie

[moxican]

As a second thought, I stacked a couple without drizzle just to see, and those did not have that problem in the middle

[Freddie]

Hi, yes that is what I was referring to. The problem is that if you open an image in R6 with a low histo and pick NO for the stretch, it will stretch it anyway!! When it does the stretch, it then over does it slightly and over exposes the middle of the image. I was surprised when I realised it ignored the NO stretch instruction on low histo images.

[moxican]

That's great info Freddie, thanks. How do I avoid this issue. I have Astraimage 3.0, that have wavelets, is that any better?

[moxican]

Not to mention that as far as I know automatic RGB align is only possible in R6, which again requires me to open it in R6, thus stretching will occur.

[Freddie]

I would stick with R6 but just keep an eye on it to check if it does a stretch. If it does, just put your stacked AS!2 image into PS and use levels to do a small stretch. Put that image into R6 and you will find that it will no longer do the stretch. You can check all this by taking one of your images from AS!2 put it into PS and use levels to darken it. Now put it into R6 and tell it not to stretch, it will ignore you, stretch it anyway and over do it for good measure !!!!!

[Space Cowboy]

Very nicely processed images Mr Moxican.

[moxican]

So I couldn't resist and had to try and fix one of the images. The stripes in the middle are not R6's fault. I stretched in Astraimage too and came out the same way. There was something wrong with the way I set AS2 up for stacking I think. Like I've posted above I was stacking with 1.5 drizzle, maybe that's the culprit.

None the less I took to CS5, selected the middle portion and applied a very small amount of gaussian blur. Like 0.4 It seems it did the trick. And since the middle part was not overstretched anymore I was able to apply a little of bit of more sharpening. Here it is

[knobby]

Really nice

[Freddie]

Very nice work but I think it still has more to give. If you put the image into PS and check the saturation you will see that the middle part of the image is fully saturated and therefore pure white. I'd have a look at the unprocessed image and if the original files from the AVI aren't fully saturated you have more detail in that middle section that you could pull out.

[Space Cowboy]

Yep Freddie is spot on that last image is too bright across the centre. Drizzle wont cause this to happen. Maybe your monitor is a little dark and you are not picking this up?

[Trevor N]

Excellent images. Well done. Trevor

[moxican]

Ok I am seeing what you guys say and agree. But for some reason I can't really fix that problem much, Here is an effort trying to fix again.

I also try to attach the original TIF before R6, we'll see if it lets me
