I agree with Exorcist that the sentence is correct. However, I do agree with Marc that the sentence is awkward and I think his alternative is better. You could also say: "I looked at the sun and for the next ten minutes wherever I looked I saw the image of the sun. "

Yes it is correct. You have the option though "I was seeing the image of the sun OR I saw the image of the sun"

Hi, To me as a native speaker the sentence is incorrect, it does convey the information but just sounds awkward. I would say something like. "I looked at the sun and for the next ten minutes wherever I looked I could see the image of the sun. " Hope this helps.

“Can l say "I looked at the sun and for the next ten minutes wherever I looked I was seeing the image of the sun. "? “ That’s also fine, in my opinion

It's fine without the comma. But as the others have stated, it's too wordy. Generally speaking, brevity is the way to go.
