I agree, it still looks like movement to me. Mirror slap, maybe? Is your connection to the tripod nice and solid?

Yeah the 1/8000 came out very noisy.
Here is the 1/8000, f/8, ISO1000

Ok ill try shoot in live view and not with mirror lockup.
Yes very solid and very heavy, high quality tripod. Should I add more weights?

A few things I've found out with the moon.

Use a tripod
Don't use image stability
Use manual focus only via live view

Spot meter and when doing so don't deliberately overexpose because it appears white. It isn't, it's pretty much middle grey.

1/160 second is fine as a shutter speed...

http://www.facebook.co​m/Chrisgilesphotograph​y (external link) - from last night

Use mirror lockup, use a remote trigger. It takes about 4 seconds for shake to completely disappear so be mindful of this when you press a button to put the mirror up.

The image you have posted so far are either out of focus or suffer from camera movement.

Lastly, it's easier to manually focus a lens if it is pointing straight up as the weight, motion and vibration goes downwards. If the lens is directing out and away across the horizon then it's very hard to manually focus. also, atmospheric distortion is more present on the horizon.

Have fun :D

that seems really really noisy for ISO 1000. Not sure if it's supposed to be that noisy normally. If you had to bring up exposure, again, that adds to noise. Not sure if it was mentioned, but also adding contrast and sometimes sharpening (depends on your technique) will add to noise.

actually, you want to try both, live view AND w/ mirror lockup enabled (just don't take the picture in live view). Both use the mirror lockup, but handle it in slightly different ways. Just remember when you try it w/ mirror lockup enabled, you have to press the shutter 2x--first to lockup the mirror and another to take the picture (unless you're using the timer).

normally, it wouldn't matter, but I'm just curious why you are getting mirror shake if you're using live view already.

Although the picture is noisy, it doesn't seem like there's shake in that last picture...not completely sure if it's out of focus a little or not though.

If you think you may be having focus issues, try using the live view focus...it should work fine on bright objects like the moon...especially if you focus on the areas w/ the craters.

Here's a moon shot that I did earlier this week, if you're interested in my process.

Handheld

I've found that ISO800 and f8 means that a shutter speed of 1/1000s works. And at that speed handholding is OK, especially with IS.

Handheld works, but I don't like high ISO - Sorry about the watermarking.....this is full size, no enlarging.

Raw mode.
Set ISO to 400
Use tripod
No filter on lens
Manual focus via LIVE view, if you have LV!
Aperture to f/9 with the TC
set AEB to 1 stop either side
Mirror lockup
Start with shutter at 1/250 or 1/320
Hit the remote shutter to lock mirror up. Wait 5 seconds. Hit shutter to take the shot
Repeat twice more for the other 2 brackets.

CHeck exposure on computer.
Tweak shutter up or down and repeat until you have your best shot.

NOTE: It seems to me that you are under-exposing slightly. Try a little brighter, and you will likely need less noise reduction. Sharpen in post.
Increase contrast slightly in post.

A pic from my 5Dc (one of the worst cameras for moon work) and an ancient, 35-year old FD 400MM lens with a badly scratched inner lens element, at 100% crop, below.
NOTE: I used a very low (too low shutter speed here, just trying it out. Turned out to be pretty sharp despite the slow shutter, for some reason!)
