Live view problem

I was photographing the "Blood Moon" and could not get a clear image on Live View. It was "blown out" for lack of a better expression. Just a while ball with fuzzy edges regardless of how I focused. I was using a Nikon D800 and Nikon 70-200 f/2.8.
I got good results through the optical view finder.
I have not had that problem with other subjects on live view.

nrjomd,

For live view you should put the cover on the eyepiece, I do believe that will help.

Thank you. I forgot to mention that I did close the flap on
the eye piece.

I did the the same during the eclipse. I was in manual mode, and when I enlarged the live view image (on 5D MII) I found that focusing was extremely sensitive. Moving the ring just slightly could easily move past the correct focus point. So I had to adjust the ring ver-r-r-y slow-w-w-ly. And got some nice shots.

Had the same problem - using the D810 with the the 80-400.
Once the eclipse was just about complete - I lost it. Could not find using live view, found using the view finder but when I switched to live view it would not show. Tried several times, switching between the view finder and live view. I was using a 2X but then removed it - still no moon.

I'm sure it was something I was not doing right, but...

Had aperture at 5.6, widest the lens goes, ISO up to about 6400. Frustrating, especially since I got some good shots of the Super Moon.

Possible your ISO was off, shutter speed and apt., was off. The moon was very bright at first. Next time meter off the face of the moon and adjust from there.

I believe you approached it wrong. It was an exposure problem. Smaller aperture is better f 11 or f14. Bulb setting, low iso 100. Remote. Tripod. Try again. Camera

was reading the sky not the moon. Think about it. Shoot manual in focus and exposure

What about Sunny 16?

Well, I used ISO 2500, f/5.0 and shutter range of 1/5 to 1/1000 depending on what I was trying to get -- either the darker or the brighter portion of the moon.

There are several things that are possible as to why you couldn't achieve a good focus. I had the same problem using the same focal length lens as you on that night. I believe the problem to be the inversion layer or clouds that make it hard to get a good focus. Also, if your moon was blown-out (too bright or over exposed) in LiveView, you should have simply used exposure compensation to bring your exposure levels down a stop or stop and a half. Some cameras can display a histogram as you view in LiveView. A D800 should be able to do that. Then you can evaluate the exposure and adjust for it. When looking at your LCD, if it looks blown out with no detail, then it is blown out. Simply adjust the exposure. So in short, you were overexposed, and out of focus do to circumstances beyond your control.
