Description
A photo of the lunar eclipse in it's early stages, from a suburban Northern California location -- in between rain clouds! A 127mm Maksutov-Cassegrain telescope was used with a Canon EOS 7D DSLR at the objective for the photo. Together, the camera and telescope forms a 2464mm f/12 optical system. This is too much magnification for the actual full moon to fit within the frame, so it only works with eclipses.Signal processing was first Adobe Camera Raw (ACR) in Photoshop CS5, then Topaz Labs Denoise.
This should be a much higher resolution lunar photo, with the new 7D. Please enjoy using this photo as stock.

That is a nice close up shot, well done. the 7D performed well indeed. I have the 7d on my wish list.

Michael,
Delighted to do a lunar shoot with you, it would be great fun!
When you start learning about cosmology, it's very humbling. And you're right: good thing numerous natural things going on elsewhere in the Universe, are not happening in our local spacetime! But even closer in, there are planets in our solar system that have hurricanes for like 700 years!
Happy New Year

that's really cool Michael! is the brown tone due to smog or processing?

Hey Michael,
Great to see you here.
To answer your question, it's neither. What you are seeing is the actual color of the moon, which (aside from the Earth's shadow) is illuminated by direct sunlight at ~5500ΛK.
The lunar surface is not white. It sometimes appears to the eye through the atmosphere. That happens because the moon is a small "light source," approximately the same size as the sun in the sky: 0.5Λ of arc. The albedo of the moon for the solar spectrum is about 0.12, which means 12% of solar irradiance is reflected. But most of that goes back directly to the sun. The effective atmospheric albedo of the moon is about 0.08. A way to think of seeing the "white" moon is that you are looking at a round, small 8% gray card in the sky that is being illuminated by a very powerful hot light. To the eye, that looks "white," because of enormous contrast differences.
Whenever you see a "red moon rising," the apparent large size and color is absolutely a cognitive illusion, what you see is not physically real. I've seen this myself!
I got my calendar dates wrong some years back to do astrophotography at Fremont Peak State Park, and there was nobody there -- that was because there was a full moon rising that night, thus blotting out the sky with glare. A really dumb weekend to be there to watch the over all sky. When the moon came up, it was "huge" on the horizon, and it appeared orange-red. But *not* when viewed through the telescope -- utterly amazing effect!
This article explains the Ponzo and Ebbinghaus illusions involved (for the moon, scroll down a ways):

The camera (via a telescope) "sees more objectively," when the image magnification is sufficiently large, and/or the exposure adjusted so that the light from a small object is not being lumped together through air, nor positioned relative to objects on the Earth, as seen by eye.
Wishing you a Happy New Year!
Blessings and Light,
M

Thank you Michael! that's a lot of information. I now know how much I don't know. I never got into astronomy seriously even though I am a big science fiction fan. I love to browse the Hubble galleries, so many fascinating things going on in the universe and thank God they aren't happening in our neighborhood!
But the moon is so close and I thought it would be so cool to get a really good photo of it but it always seems out of reach... well maybe sometime we could meet up and I could learn the basics of shooting the moon like you did.
