Extremely big and bright full moon shot with a D70 on auto yesterday evening. All of the pictures have this secondary blue-ish moon in them. Does anyone have an idea what might have caused this effect? Also - notice that the blue moon has some detail in it but not the main one. Overexposed?
I'm sorry but I can't see it.

It's a reflection/flare - Either inside the lens or between the front of the lens and the filter (if you use one). The same thing can happen shooting directly into ant bright light, like the sun.
Yes, definitely overexposed. Raw files won't display so you need to convert to JPEG, PNG, or such, first.
Laurie: The originals are Nikon raw files - they won't display hrer but you can download them.
How do I avoid this effect?
Getting the right exposure will help. Start around 1/125 second @ f/8 and adjust accordingly after viewing the histogram. If you are using Auto, try spot or center-weghted metering and target the moon in the viewfinder - worry about composition when you crop.
If you are using a protective filter, remove it.
I suspicion that UV the filter was the culprit - thanks!

Most likely. Again, if you're going to shoot Auto (Green box), then put your meter on "Spot" or "Center-Weighted" and focus directly on the moon. All of that black sky confused your meter and overexposed the shot for you.
BION: It was set to center spot and focused on the moon. I was expecting better results. The filter comes off this evening for a second try.

You've left them in a Nikon RAW format that does not allow Canon users to view them so without being able to see the images I may also suggest you look at your White Balance Settings, but I am only guess from what you said.

Not WB - the moon was overexposed and is trowing a blue reflection on or in, the lens.

Apart from the horrible reflection it is horribly way overexposed... It is a BRIGHT blob as opposed to the Moon.
1/30th sec at f5.6 is way, way way too much light.
I am in the corner that much prefers not taking pictures of a full Moon, there are different stages when there are shadows cast over the craters which will make a much more impressive exposure although a 200mm lens might not be long enough to get as much detail as you might want, but a picture of the Moon is a picture of the Moon. :thumbup:
Apologies snowbear I had this open and failed to see your post but we are in TOTAL agreement :)
I think that this is a bit better but quite soft cropped from 300mm. Your thoughts?

As you rightly state it is a bit soft but if we look up at the top right you can just make out some craters.. If we avoid taking pictures of the full Moon these craters will become more prominent.
To better explain this, think of shining a floodlight directly at a football... The stitching will be seen but if we shine that light across the ball, the crevices where the sections of leather are joined will cast shadows..
When the Sun is at an angle the light hits the sides of the craters casting shadows, which in turn make them stand out.
