Physics Earth axis

I took this picture on 02/21/2010, and I saw a line that I called it celestial pole. But I am not sure if that is what I see in the picture I took. I looked up wiki and I found that picture that the celestial pole is on the other side of the line that I see on my picture. How do I explain it that what I see on the picture I took is really the celestial pole that I saw from earth standpoint.

There is nothing "celestial" about that. It might be an effect of the atmosphere or, as far as the picture is concerned "astigmatism" in your camera lens.

What you are seeing in both of your posts is nothing more than water and ice crystals in the upper atmosphere refracting sunlight. You are not seeing anything celestial apart from the Sun's usual disc on a clear day.

The reason I am thinking that I am seeing the celestial pole in the picture that I took, because when I compare my picture with wiki picture, this is what I am seeing.
I took the picture with my camera that has two lens. At the moment, I point straight at the sun to take this picture. So as it view from earth standpoint, the celestial pole is on the other side of the earth as the sun reflect it.

If the pole were actually phyiscal then it might reflect, I suppose. But there is no physical manifestation of an axis running through the Earth.

It would be fun, though.

I heard of the earth axial tilt or obliquity and the earth circle around the sun accordingly to the earth axial tilt.
But I never heard of the sun has the reflection of the earth axial tilt.
I am curious.

You haven't heard of it for a very good reason: There is no reflection because there isn't anything to reflect from. I have already told you this in this very thread. I don't know why you are persisting in this.

It was water? I thought it was fire since it was sunlight.
