I have a question… I was up all night photographing what I thought was the Penumbral Lunar Eclipse at 1:46am 11/20/2002. I read it was hard to see but I had no problem…lol is this ring the earths shadow? If not what is it? I am confused…lol Astronomy is my second hobby but I have never watched a penumbral lunar eclipse. Some of the pictures are here.
some of those pictures are very cool. I think that is lens flare though, rather than the Earth's shadow :)
After posting this I found out a bit more about what a penumbral eclipse is, so there never really is any 'cut' shadow on the moon, the moon just moved through the darker slightly shadowed part so got dimmer. Less visibly dramatic I guess. I got one picture though, not as good as yours.
That is not the Earths shadow (as far as I know), a) because the earth doesnt have a hole in the middle and I can clearly see the moon in the photos and b) because what would the shadow be casting on?
I think it is just a lense flare... or did you see this ring in person?

I saw this ring in the sky around the moon. It's not lense flare I saw the ring...lol

Originally posted by BigSmiles: What is pictured are Moon rings. The ring around the moon is caused by the reflection of moonlight from ice crystals in the upper atmosphere.

It's a refraction of the light through water in that atmosphere... If I remember correctly, if you count the number of stars you can see within the ring, you should have rain in that many days. While not a scientific method, I've known it to be fairly accurate.

Gordon, How did you get such a close shot of the moon? That's so cool! What did you use? [/i]

Great shot! You might want to submit it to one of the numerous NASA sites if you want more brownie points...Would you be able to post a photo showing the setup you describe above?

I would more than happy to show a picture of the setup, but it will have to wait til tomorrow evening, so i can get someone else to take a picture of it.
I have links somewhere to several space-science related sites, including several run by different parts of NASA. Why don't you take your time getting the setup shot, and I'll scout around for and "package" the appropriate links.

A 300mm lens and a tripod

Alright maybe I am getting closer than I thought. I have to get my film developed to see. I used a 500mm mirror lens last night for the first time. I hope I had the settings right...lol I am still learning.
