Can anybody tell me what I did wrong with these photos of the moon eclipse on the 27th? I used a 100 to 300 Sigma lense, tried to compensate exposure and when I did that the moon just whited out. From where I was shooting it was over town lights. Could that have had some effect? I'm sure it did.

Can you give more info on your setting? The first one looks underexpossed and very noisy. No need to use high ISO for these shots. The second looks overexpossed and a bit out of focus.

Well I used Autofocus to focus, on the brighter picture the shutter was 1/200, aperture 5.6, ISO 800 with -2 exposure compensation.
And the other autofocus as well with shutter at 1/1000, aperature 5.6, and ISO the same 800 with -2 ex. comp.
I was 50 miles from Seattle, WA. It started just when the sun went down.

I have three tips for you that may help.
1: There is no reason to use 800 ISO. All it does is add extra noise into your image. 100 ISO on a tripod should be fine. I think I used something like 1/125 f/9. This gave me good exposure on the bright side.
2: Trust you eyes. Sometimes the autofocus can be misleading
3: No camera out there has enough dynamic range to show what the eye can see. I used two exposures for each of my shots. One for the bright side and the other for the dark side and used Photoshop to put the two together so it looks more like what the eye sees.
I hope this helps and best of luck. Here is a combo of the two photos I had.

The 'trick' is to realise the moon is a bright, sunlit object. You can then just use the 'sunny 16' rule to work out a good starting exposure.
so at ISO 100, you'd shoot at f16, 1/100s or so
Given that the moon is not really a mid grey - probably you want it slightly brighter, so open up a bit more.
f16 1/90s or so, ISO 100
You can then play around with that to get something down around f8, and
consequently upping the shutter speed.
The moon also moves quite quickly really across the sky, so you can't get away with long exposures and expect to get a sharp result.
You want to play around f8 or so as that'll be close to the sharpest aperture for your lens.
Vibration is also a big deal, even on a tripod. You should at least use the timer on your camera, so you aren't pressing the shutter. Also pay attention to where the tripod is standing - if there are vibrations, you'll get a soft result.

For most of the eclipse you have a choice of exposing for the dark or light side of the moon. You may want to try both next time and see if one comes out better. I snapped off a series of both sides so I could choose whichever came out best.
