1/2 second
f/5.6
ISO 400
135MM
tripod
remote trigger

I only have the 28-135 lens, but that doesn't tell me why i didn't get the clarity. what did i do wrong?

This was the only "decent" shot that I got before the clouds started rolling over and i got too cold (North East Ohio)

shutter speed is too slow. the moon is moving and at 1/2 sec you will get some blurriness to it. i would have bumped up the iso to get a faster ss. great try though. still a good image.

thanks for the input

I personally think your shot looks good for 135mm. I took a few in East Tn with a Sigma 300mm. I don't think your shutter speed was a problem. I just think thats an actual size and you need more zoom for more detail. My shots are no better.

Here's about 6 shots combined at 300mm.

Hudsonp,
I also got shots that turned out like yours, Good but not good enough to make me jump for joy. I was doing this: tripod, remote release, mirror lock up, F/2.8, 200mm, 1.7x, ISO400, IS on and in mode 1, EXIF shows 1/8th but i was sure it was more like 1/400th. and this is what i got, oh ya and some frost bite.

No PP done, this is right of the card. I'd also like some pointers.

Your image looks reasonably good to me. The "clarity" as such is affected by many parameters:- dust in the atmosphere, moisture in the atmosphere, how much atmosphere you have to look through to see an object, etc. Astronomers use terms like "Seeing" and "Transparency" to describe these phenomena. Check out the Clear Sky Clock (external link) for a complete description.

Also, a reasonable guide to shooting the moon can be found at: - http://home.hiwaay.net …moon/howtophoto​/index.htm (external link)

I've read that image stabilization can actually hamper night shots. Could this be part of the issue?

Not sure, I think it as to do more with the range of the lens but I'm no expert so I can't really say.

I had everything ready to go, but it was so cold and my remote didn't work right, so I had done the timer, etc. I did everything I did before, but I think it was me shaking from the cold. :( I got similar results.

I'm going to set up in a different place, have my 5D this time instead of the 40D and use the extender and the 70-200 is. The f4 didn't work right this time. So, it's never perfect, just keep trying new things. Your shots aren't that bad. The moon's really far away.

Shouldn't make a difference. Check here for shots of the moon/eclipse taken with the Canon 75-300mm IS lens:-

Look in the "Astronomy" or "Moon" folders.

What does this look like at actual size? That lens should be sharp enough to use a 100% crop shouldnt it?

You didn't do anything wrong. You did the best you could with the equipment you had.

Shooting a full moon in a clear sky isn't so hard. It's very bright so you can use ISO 100, f/11 and 1/100 shutter speed to get a nice, clean shot.

The moon in eclipse is so much darker you need to compromise everywhere to get decent exposure. A higher ISO, wide-open lens and a slow shutter speed mean digital noise, softness and a small amount of motion blur.

Photography is recording light. If there's very litle light to record, the IQ will suffer. Simple as that.

This is the complete shot. no cropping done. All i did was change the file size so the web site would take it. I am no good in the computer so for touching up and things like that i don't do much of it.

Thats what i meant, If you could use it at actual size then it would be a lot bigger. Not sure if that lens has the IQ for that or not. I know my Sigma doesnt.
