Caboose is your picture 1:1 crop ... it really looks to small. For example I've used 300 x 1.4 = 420mm (x1.6), you had 200 x 2 = 400mm, so very close but "your" moon is much smaller?

I'm going to try posting that picture again, I don't think I picked the right file the first time.

Hi Squirl - knew I would find you here. Great shot with unusually clear craters all over the moon. Most published photos (including mine) seem to emphasise one side more than the other...Fred

hi Fred,

yeah, i figure now i can post on TWO forums! :G that Sigma lens seems to deliver some pretty sharp images. i took this same shot with my FZ20, and it came okay, but not as smooth and clear... to be expected, i s'pose, with 3 more Mp in the Canon....

Can I play? I took this about an hour ago. ISO 200, f/8, 1/160. I think almost all of my shots were a bit overexposed. I took a bunch using "spot" metering and bracketed all over the place. I think 2 stops further down would have been better and to get the highlights more detail... Oh yeah, taken with a 20D and Sigma 70-200 EX with 1.4x

wish it was clear enough here to even SEE the moon, much less photograph it! you got the exposure right, but it looks like it's been really oversharpened - too contrasty, and lots of artifacty looking spots. what kind of post-processing did you do?

I did a quick run through on DxO but then I did sharpen and deepen shadows quickly in Picassa. I reduced the exposure -2 in DxO but I think it could have been more to get the highlights right. I used the shadows to help but ended up with the contrast problem. Here is a Photoshop version. There still seems to be less detail than I wanted. Not sure if it is a focus issue or just general weakness of the 1.4x tele.

this is the advantage of shooting at 1/400, I took this shot hand held, f11, ISO 200, 1/400. Normally I would use a tripod for a shot like this, but if you don't happen to have one with you, you can still get a decent shot using the faster shutter speed even at ISO 200.

I think that at higher magnification picture quality will also depend on the fact that air is flickering which is almost always the case in urban surroundings. Most of us live in town or city so this has to be taken into account.

Best picture would be (also have 8" telescope but didn't use it for photography yet) outside of town at some quiet dark place on some high mountain.

So far, the first moon picture is still the winner!
