Shutter speeds?

1/125 for 1200mm on 10MP APS-C in my case.
A bit on the safe side, could probably have been down to 1/80 without problems. With LiveView at 10x zoom, the moon was travelling fast across the display

Some of the posted images show, that atmospheric haze determine the quality of moon shots more than anything else.

p.2 #4 · 7D + 800 moon shot

So, I wondered how the 300mm F2.8L IS would hold up using stacked 2.0 and 1.4x teleconverters -- here is a Halloween moon on a 1D Mark III, f/11 at 820mm 1/200 sec.

Downsized from 1200x1200 to 600x600:

I accidentally took the picture as a jpeg, so it's a bit blown out at the edges -- I thought I was in RAW. Some contrast enhancement and sharpening applied.

I didn't know you had an 800L dolina. How's it feel to be one of the few in the Philippines that do?

It feels heavy but not as heavy as the 400 or 600.

Getting much closer to the subject.

Here is a montage of three images taken with the same camera/lens configuration about 6 years ago:

Canon 60D (6mp) + 400mm F5.6L + 2xTC (EFL=1280mm)

I wish I had the reach of the (18mp) 7D then!

I usually shoot moon shots at around 1/125. 1/250 is preferred. The moon at night is much brighter than you might think and internal exposure meters on a long lens is unreliable; at least thats my experience. I always use a remote shutter control to eliminate, or at least minimize camera shake. I try to stop the lens down as much as I can and bracket both shutter speed and f-stop. Results are very acceptable. Of course a lot all depends on ISO setting. 400 is my preferred ISO

Each man has his own cross to bare. Mine just got 1 kg heavier but much more sturdier.

BTW I really like Tim's shot. I wonder how he made it so highly detailed.

Tim's shot is absolutely awesome. Well done!

I created this montage with my 7D quickly tonight (hand-held) using a 70-200mm F4L IS, 400mm F5.6L, and the 400 with a 1.4xTC.

It's a full moon, and the Columbus skies are a bit hazy, so it's not so sharp, and the lighting is really FLAT!

This was the best I could do, with a Mamiya 300mm lens and I think a teleconverter on a 40D and very robust Canon tripod. Having shot the moon a few times, I appreciate the level of equipment it takes.

Then, there's the person operating it, the waiting, spotting, etc. etc. It's not child's play, and you guys have posted some really impressive shots. If only I had some extra reeeeach.....

BTW, at a larger size, this image falls apart. Not like the JUMBO stuff posted here, it's enviously smooth.

FWIW, let nobody say that Los Angeles' air is THAT crappy!

Let's not forget that mother nature "trumps everything," including the best sensor, glass, and mount.

You've got to have great viewing conditions in order to do any kind of astrophotography.

Just ask Russell Croman.

Another moon shot, this time with 800 mm. Well, 400/2.8 and a 2X teleconverter...

From last night.

7D, 1/400, f/8, ISO 200. A pretty good combination for moon shots, though I think that the 800/5.6 lens offers a bit more detail.

Nice moon, Breitling65.

One of the things I've noticed with the 7D is that it doesn't AF reliably with stacked converters like the 5D2 does. I put the 2X and 1.4X on the 400/2.8 (which reports to the camera that it is f/5.6 even though the combination is f/8) on the 5D2 and I still get center AF point autofocus fairly reliably. With the 7D, this doesn't happen consistently. It's a hit-or-miss, with more miss than hit.

Oh well, I'm cheating anyway, trying to get AF on the moon with what's essentially an f/8 lens combination. I did try the stacked converters with the 7D anyway, taking care to manually focus both through the viewfinder and through live view. My best result had a bit of CA, and I think that the 7D might be outresolving the combination just a bit. My best stacked result, when reduced to the size of the 800 mm setup, was still a bit softer than the crisp result that I got with 800 mm. Could be a focus issue though - AF has always been better than my eye through the viewfinder, especially when the camera is pointed upward so much.

I'll give it a few more tries before I give up on the stack. In the meantime, the 800 mm 7D shot still lands more pixels on the moon than the 1120 mm 5D2 shot. And that is a big plus!

What a great age we live in where we can capture images like this with relative ease ... compared to only a few years ago, in fact. Thanks for posting.
