First time shooting the moon

Full moon tonight so I thought I would give it a shot. Using 70-200 at many different settings just to figure it out. Not sure these are sharp enough but at 200mm I had to crop to 100%. Please let me know what you think and any ideas to make them sharper...other than buy another (bigger) lens.

Thanks for looking...

That's a great start, in my opinion they look a little overexposed, exif is showing 1/160 at f/8 ISO 200. I would try it on ISO 100, 1/125 at f/11 and see how you like the results. Especially a full moon you have so much light to work with don't be afraid to close the aperture a bit, goto ISO 100 and fiddle with the shutter at that point.

Thanks, I also forgot to mention I was using my video tripod which doesn't really support the camera very well, so maybe a little shake when pressing the shutter. I may just have to get myself a new tripod and stick it under the xmas tree for a couple weeks. I would assume at that distance, even the slightest shake would cause some blur. I don't know if IS helps with this type of shot.

Not sure what I did wrong but I kept trying to get ISO at 100 and it wouldn't let me. Anything below 200 went to auto which set it to 400. I tried with IS off and on. Shooting RAW. I have a few at f/11...I actually tried some all the way up to f/22, just tinkering trying to figure it out.

Thanks again for the input,

I like to use the timer to eliminate any induced shake from pressing the shutter.
I have also read that you should not use IS when mounted on a tripod.
Here is an example of one I took the other night with my 70-200 with 2x telecon.
I think the settings were iso 100 f8 and 1/320. This was also handheld.
Probably not the best example of a moon shot but I kinda like my results.
Bigdogs setting are a great place to start by the way.

The timer...can't believe I didn't think of that one. Thanks.

I tried both with and without IS and the shots came out nearly identical, but my thought was that on a tripod the IS might actually cause some blur (except that my tripod could not even hold up my camera with the 70-200 on it and was shakey to begin with).

Great shot! I did some handheld and they were ok but not as good as on the tripod.

yeah definitely shut IS off and use the timer to eliminate the shake. Here is one that I shot with the 400mm lens, ISO 100, f/10, 1/125
