I was messing around taking pics of the moon, and one came out like this..

I know theres not another sphere next to the moon, but why would a pic come out like that? I was using a tripod, but was pressing the shutter button on that one so there was a little shake.
I took about 50 photos, that didnt appear on any others

Thanks

Yep, lens flares are cause by internal reflections inside the body of the lens (there's a lot of glass in there).

Thanks for the quick answer.

Somehow didnt occur to me given it was the moon, but makes sense!

Btw shooting the moon is like shooting the sun. You use a pretty high shutter speed.



Was taken at 304mm F/8 @ 1/320. With a wide open aperture you can use speeds of up to 1/2000 and still have a bright semi detailed picture of the moon. Slow speeds just show a bright white moon.

Sorry it's a bit low quality it was a 3MP Point and shoot.

I was confused at first and then figured it out.
I still had trouble getting details but some people here helped me out alot.

1 - Use Centered Auto Focus if just shooting straight at the moon.
2 - Stop down to a small aperture
3 - High shutter speed (camera tends to mess up so just go full manual)
(Something about the rule of the Sunny 16 look it up apparently itll tell you approx what shutter speed to use at that particular aperture.)

Tripod helps some but for the most part i had almost asmuch luck hand held.

You should get a better picture then me I shot at 304mm 35mm equiv which would be 200mm on the Nikon. Use whatever u have.

I know everybody's saying lens flare, but it looks very much to me like a diffraction caused by a cloaked alien ship passing between us and the moon, and you just happened catch it in this shot.

That's no moon, it's a space station!

Try shooting at the moon in the daytime, or right at sunset or sunrise. Here are a couple from my portfolio. The sunny 16 rule applies if you want the bright side to have detail. It is a completely different shot to get the dark area, but it would be difficult to get detail in both areas in one shot. Shooting details are with each image.
I suspect that the anomily in your image is what is called a "ghost image", an internal reflection in the lens or off the sensor and back to the lens in the camera. A UV or other filter on the lens can cause that sometimes too. The 3 images were shot right around sunset. Good luck with your moon shots. I hope the numbers with the pics will help.

This turned out to be a great free lesson.
I did have the uv filter on too.

Well Ill be out again tomorrow with a better sence of what to do.

Thanks again!

Two helpful links for shooting the Moon:

yeah... ansel adams apparently liked to remind people that the moon is a sunlit object, just like something you would shoot in the day time. the following pic was at f/10, 1/125 sec

The Moon, Saturn, and the star Regulus will be in close alignment (conjunction) tonight.
