I imaged the full Moon tonight with my AP155EDF operating at F5. I

decided to try taking red, green and blue channels and combining them

to create a traditional color image of the Mooon. The colors are

there, but to see them clearly I had to boost the color saturation.

Below are two links, one to a smaller version, and the second to a

larger version. There is also an Ha image for those preferring the

traditional monochrome view. Image scale on these is approximately 1.8

arc sec per pixel, so the resolution is not high. The images consist of

a single exposure per channel, with 0.5 sec for the Ha channel, and

0.11 sec for the RGB channels. I used an SBIG ST10XE camera, and with

its minimum exposure time of 0.11 seconds I had difficulty avoiding

overexposure. I ended up having to add a 13% neutral density filter to

get the light levels down. Best regards, Mark Manner

Very interesting, Mark.



At first, it struck me as odd, indeed. I wanted less color, especially

magenta. But the more I looked at the color image, the more fun it

becomes. First, it is much more three-dimensional than most full moon

pictures, which tend to flatten out the detail. Aristarchus, already

one of the things that always draws my eye at the eyepiece, stands out

even more so in your picture, and the highlands around it jump out at

me. The rays emanating from the major craters are also more priminent.

And the differences in color in adjacent maria is much more evident.

I'm no geologist, but it becomes apparent to me that some are older

than others, and/or made of different types of material.



Thanks for showing us the picture.



BTW, I see you've branched out into radio astronomy. Is it up and running?

Thanks, Ronnie. I had the same first impression as well. After

looking at it some more, I like it, particularly the large RGB only

version. As to radio astronomy, the SRT won't be here until the fall

probably. I don't know why so slow, since I can't imagine there is a

run on them. When it arrives, you can help calibrate it. Mark

Mark, beautiful images !!! From the looks of it we must have been imaging

at about the same time. Mine however is shot at f/8 with a cheap Achro

scope who's name I will not mention here g>. Still on the ole list for a

real scope.
