Moon Shot: What Am I Doing Wrong?

Ok, took some moon shots of the Harvest Moon last weekend, and went all over the board for settings from F/5 to F16 and shutter times of 150 - 350. 5D2. Canon 75-300IS (IS turned off on tripod). Remote switch. 100 iso. Kenko 1.4x TC.

And this is the best shot I got, which doesnt look anywhere as sharp and clear as other shots I have seen with the same 75-300/1.4X TC that I have seen.

Can anyone tell what I am doing wrong? To much ambient light around me, maybe?

This is 100% crop.

The one item that is missing from your list is a tripod - I assume one was used?

he said on tripod lol
Rob.

lens?

ambient light wont effect it much , were you outside for the shot ?almost looks like you shot through an open window and heat from the house leaving the window has caused a sort of heat haze.

Oops. my mistake, I missed that!

I think possibly that 1/200 @f/5.6 is a bit over-exposed.

Looking at the pic, it just looks out of focus? Maybe the lens needs a bit of micro-focus adjustment. But for moon shots, try using live view to focus. Zoom in 10x and you can nail that focus. For settings, use the moony11 rule of thumb. f/11 and the sped set at the reciprocal of the ISO. With the 5D you can easily shoot at ISO 800 without penalty of noise. So backing the lens down to it's sweet spot at f/8, you get f/8 at ISO 800 and a shutter speed of 1/1600. At that speed you should practically no vibration induced issues.

Heres what I used to get this. See link

Along with M Lockup, Live view focus, remote release. Wait about a second or two after locking up the mirror, them release the shutter.

It was shot outdoors, yes with tripod.

Most of my photos were actually under exposed as I moved through the settings. Even having EC set for three shots, 0, -1, +1.

Perhaps it is the lens needing micro adjustment, as mentioned. It's been awhile since I used this lens, as I tend to rely on the 70-200 f/4 IS these days.

I haven't tried using live view (in fact, I have never used it! Must learn...). Makes sense that it could be the answer I am looking for as far as focus on this shot is concerned!

Beautiful shot, Stargazer! And that was the result I was expecting from my setup.

Thanks, guys!

For moon shots, nothing beats live view. You can zoom in to 10x and get a perfect manual focus.

I'll give it a shot! And higher ISO.

BTW, before anyone tells me the lens is crap, I should qualify... it's the 75-300 USM IS, NOT the 75-300!

i shoot the moon at 400 iso 400 shutter and f/11

and i shot this as a result
