Stock 20x lens with Canon 1.6x extender, WB color temp dialed all the way down to 2800K.

And the same shot using Steven Dempsey's Disjecta preset.

You can't help but get into chromatic abberation territory with such extreme telephoto.

Nice! I took a shot myself a couple of days ago....

That's not chromatic abberation I'm seeing in the second shot, it's due to the fact that the moon is made of green cheese. Didn't you learn that when you were a kid? ;-)

I guess I shoulda made it green... anyway here are two more (added to first post above). One at twilight, the other in black and white.

so is chromatic aberration what creates the blue moon effect? or is it the WB? i shot one of these incidentally, and i was wondering why it came out that way.

i also have a green cheese moon with a strange reflective ghost moon (actually i think the green moon *was* the reflection) and i couldn't figure out how this happened....anyone know?

Nope, the chromatic abberation just spoils the shot a little. The blue effect in that first image came from dialing in a White Balance of 2800 degrees Kelvin.

Greg, you wanted green cheese... here it is:
