Shooting The Moon Failures

Hi all: I've got a 5d/II with a 500mm/f4 lens and 1.4/2.0 extenders. It rests on a medium qualityBogen tripod (~$110) and the WimberlySidekick Head . Obviously my equipment is far better than I am. I recently tried a second time to shoot the full moon at 4:00AM on a clear morningand failed miserably. I don't know why I want to do this as there are stock photos better than what I could get but I guess that's part of the bug.


In any event, I'd like some tips on how to shoot lunar photos using the equipment I have. I've searched here and studied what is available at sites like telescope.com but I really think I should first see what I can do with my setup.


So, I tried the following:


metering from full frame to spot/Av with apetures from 5.6/8 to 14/shutter speeds set by the camera based on my settings/iso from 100-800/exposures adjusted from full 'left' to full 'right'/remote controlled shutter release and bulb (but I don't really understand bulb, I was just trying to get it right)/manually focused via the viewfinder first/


Every photo turned out with the moon blown out severely as well as blurred. I can see craters/details in the viewfinder but the photos all come out simlarily useless. Obviously I'm doing something grossly wrong but I'm at a loss as to what to try next.


I do appreciate what I've learned on this forum. It's helped me get some great photos of other subjects but the moon has eluded me. Thanks again, gary

try increasing the shutter speed some more and use spot metering. since you're getting blown out shots, the objective is to try to get a bit of underexposed shots first then work from there on getting the right exposure.


i don't recommend bulb if you want to take snap shots of the moon unless you're using a really small aperture.





hth :)

The theory is that the moon is basically lit by the sun so you need to photograph it just like you would photograph something on earth lit by the bright sun. Try 1/00 at f8 with an ISO of 100. As to the blur, I am going to suggest just use the 500 mm and crop. Good luck. I would post a pic, but I haven't had any good results either.

I use spot metering and ISO 100 and manual exposure. Both taken with the 70-200 f/2.8 non IS

The moon is a lot brighter than you think, I used AF in both pictures, and they are both cropped...mirror lock up and 2 seconds timer were also on... hope this helps

First of all, I suggest manual exposure. Forget the meter and just play with the exposure until it is what you want. Sounds like you're over exposing. I would also suggest, just to make sure the issue isn't tripod jiggle, that you set the iso to 1600 and get a really high shutter speed. If that is sharp, experiement with lower iso. When it starts to get blurry, it means your shutter speed is too low.


You should carefully manual focus with live view (zoom in to 10x to get it exactly right).


I would also stop down as much as you can and still get sufficently low iso and high enough shutter speed (but not beyond f/10 or so because then diffraction is an issue).


I also agree with the suggestion that you first try without the extenders. There doesn't seem much point in using them unless you get something that looks sharp viewed 1-1 without them.


I don't know how blurry you mean by blurry, but the atmosphere is often the limiting factor. The picture below, taken with an 800mm f/8 telescope, is blurry. Not because of bad focus or shake (it was on a sturdy mount), but just because of the atmosphere. And this is nowhere near a 1-1 crop. So with a 500mm, extenders may not be needed unless you have steady air. (The exposure for this picture was 1/10 sec @ f/8 and iso 100 was used)

@jon, thats on 1/10 f8? that's a cool picture! I always wanted to take a good shot of the moon. but all i have is a 250mm :P

Shooting the moon is easy, shoot in manual mode...set your aperture at f/5.6 or f/8 ISO 100...increase the shutter speed if your moon is blown out, decrease the speed ifit's too dark, check your LCD after every shot. Test shoot the moon now and practice for next full moon [:D]

Also, try to shoot it when it's high up, if you can. Goes through less atmosphere.





Saw a cool blood red moon a few nights ago in Kentucky. Unfortunately, it's blurry (atmosphere)


This is a cropped and downsampled image I got with a 30d at a 400 f/5.6 with a 2x extender. I don't know how to look at the metadata on photobucket, but I think I was doing like ISO 800, 1/250s, f/16, or something... I'd like to try Nate's settings on a clear day. The noise was significant. I wanted the fast shutter speed because even with the mirror lockup and remote release, I seemed to be having problems on most of the shots (didn't have live view either :( )

Full crop of image....


You can see the noise issues in this.

Good point, Colin. That's important.


One more thing. When a lens has a significantly different temperature from the surrounding air, it causes an unsteady image. This isn't really a factor with little lenses, but a 500mm f/4 might require some "cool down time" if brought from a warm house to the cold outside. I don't know exactly how much, but I'd try waiting at least an hour with the 500mm f/4 and a 25 degree (F) drop to see if there is any improvement.
