Here we have a final image from an AVI I took of Jupiter on the 14th April.
I'm just conducting a little experiment on the wavelett side of things on this particular AVI.
Particulars of this image: 250 stacked frames. On top of my natural image scale: (F10 SCT/2X barlow/70mm extension tube) I have resampled @ 1.4X And then saved the image 200% bigger. (1790X1342 pixels)
This image is meant for thumbnail viewing, if you 'biggie size it' get ready for an eye full of grain!!
The next image I post will be the same image & size, only processed in Picture publisher 8. The one after that, will be downsized/cropped etc. to give the final image.
Actually, the outcome will be a long, drawn out process! My intention here will be different wavelett settings......so after this one comes another one at different wavelett settings! Oh hell! what have I taken on here!? As you know, wavelett settings are almost infinitely variable, lol I may have to narrow the experiment down a bit.
Since you've gone to the trouble of resampling to such a large format, have you tried Birds technique? That is:
1) save the stacked result as 3 FITS files
2) fix them with Birds fixfits utility
3) read them into Astra Image or MaximDL
4) perform deconvolution, highpass filter etc operations
5) RGB combine (they are aligned already by Registax)
6) perform color balance and saturation operations
7) Unsharp masking
When you do this make sure you have NOT used the wavelets in Registax (all ones). By the way, there is a lot of good data in your image and it looks very promising. Assuming you have a good noise sample outside the planet face, the deconvolution should give you a much less noisy result.
If you dont want to do this, and use wavelets, it seems to me at this scale the lower (finer) scale adusters should be minimized, and the larger ones should be manipulated, or the reverse of what you posted. Using wavelets at this scale is tricky as it requires possibly changing the default Registax settings, and then you have so many combinations that it will drive you nuts (at least it did me).
Hi Glenn. Thanks for your input. I have performed most of the suggested operations already.
1: My laptop won't save as FITS.
2: No.
3: Yes.
4: Yes.
5: Do you mean splitting into RGB running thru registax seperately & recombining?
6: Yes.
7: Yes.
To date, this is my best result. I will post again shortly to explain further.
This is info I wrote in another thread, so this is not the EXACT proceedure used on this particular image, but something fairly similar:
I use picture Publisher #8 as my image editing software. First I take the image & give it 2 points of less gamma on all 3 red green & blue channels. Saved. Went back into gamma, 1 point less of the blue channel. Saved. Went into tone balance, up 4 points on highlights. Down 1 on midtones, up 2 on shadows, saved. 5 points of sharpening, 1 point of unsharp mask, saved. Went into hue map option, in there I have 11 colour/hue sliders. Tweaked 5 colour hues. Saved. Saturation shift, up 1 point. Saved. Resized smaller, Saved. Back into sharpening, up 2 points. saved. Down 6 points of despeckle. saved. Into Colour balance, up 5 points of contrast on red channel only. saved. contrast/brightness, up 2 points on all 3 red green blue channels on contrast, down 1 on all 3 channels brightness. Saved.
Asi,
I was suggesting saving the color image (without Registax wavelets) in Registax as separate FITS. This is a function of Registax, should be possible with your laptop.
The RGB combine I suggested would happen in Astra Image or MaximDL.
Anyway, your image looks great as is, just more grain than needed. Wavelets tend to do that unless tweaked carefully.
Thanks for that Glenn. I understand now, & I shall try your suggestions. I did a further processing of the same AVI but with different waveletts, & it came out better than the last image posted here.
By doing this little wavelett testing thread, rather than showing my images I'm trying to show people not all that familiar with imaging/registax/processing what happens to an image when you have the waveletts set a certain way. I never have the waveletts set this way normally. Normal for me is: 6-40 5-25 4-15 3-1 2-1 1-1
