It's not blinding. 8O Is the regular moon blinding?

Where I live, the air is thin and very clear, so a full moon can hurt my eyes. However, I am sensitive to intense light so maybe it's just me.

My apologies, I was using "blindingly" non-literally, as a figure of speech. Although, once night vision has been achieved, looking at the full moon can certainly bring about a large reduction in the ability to see compared to full dark adaptation.

The scale runs backwards, big negative numbers are super bright & big positive values are super dim. And it's not linear.

During the brightest full moons, the Moon can have an apparent magnitude of about −12.6
By comparison, the Sun has an apparent magnitude of −26.8
Vega, the fourth brightest star in our sky (including Sol) has an apparent magnitude of 0.0
6.5 to 7.0 is the limit of what we can see with our naked eyes at full darkness adaptation ("night vision"); anything with a larger positive number is too dim and additional light gathering optics are needed.

So, if your eyes are adapted to see objects of an apparent magnitude of 6.5 and you look directly at the full moon, they'll quickly adapt to -12.6. Once the afterimages fade, it'll still be another 10-20 minutes before you can see any but the very brightest stars. Under those conditions and given the reason one might be outside, it can be considered "blinding" in a loose sense of the word.

That's the best I got.

It's not easy to photograph this because 1) it's rilly far away, 2) the contrast is extreme with the bright part of the moon basically in broad daylight and the dark part in who knows what.

Would be awesome to have a photo from the moon's perspective.

Very nice! Telescope, or cropping from a very hi-res pic?

Just a camera on a tripod. I could have done better if I'd read some tips beforehand or if I'd ever read the camera manual. But in general I'm really interested in low light photography right now. Not trying to take a perfect documentary image, but trying to catch some sense of mystery

I couldn't see it in my area, I hope to see the next super moon in 2033.

There will be another super moon (full moon at perigee) October 27, 2015.

Lunar eclipse schedule: http://eclipse.gsfc.nasa.gov/lunar.html (I don't know where you are located, or I'd have just cut-n-pasted the next one)

But yeah, both together...have to wait 18 years.

However, if you in the western USA, there will be a total solar eclipse in 2017 and a few other events between now and 2033. :)
