Somebody Know the de-onion filter?

This last Friday I was able to photograph Jupiter. Unfortunately, I
forgot any parameters and I have a few flaws that ruin my image.

I'll see what I can do for you as far as fixing it goes, but it'll have to wait till tomorrow, Right now is not a good time for me to be doing anything complicated....it's 4:25am in the morning!!!

Wow that's pretty extreme.. how did you manage that? What were the settings?

Hello.

I believe that I forgot to type in the computer that AVI must be without
compression....

The images of Saturn that I got a few hours before and yesterday have no
onion. ;-P

Today is cloudy, but the end of next week I try again.
Jupiter is acceptable to us from 2 am and if the following day is a working day waiting jupiter is not very comfortable. :-(

I found that if I do four copy layers in PS, I modify the transparence in order each layer have the same weight and I displace one pixel each layer (up, down, left, right ) the image have a small blurr and the onion is not so evident.

I think the best bet is to just go out and try again

My experience with onions is, no gama = no onions; use gama and you will find onions.

Yes Iceman, this is the best way. The questios is why I have obtained onions now, after the Mars and Saturn observation time.

Lester, what you say is very interesting. I modified the gamma of the camera for that image. Yesterday, with very bad seeing I try again without changing the gamma and I have no onions. Thank you for the trick!!!

Glad it works for you too Pelu.

I never use any gama on planetary capture.
