[quote=zardoz] I found ‘em.

Have you shot any stars with 20-30 minute exposures that leave the streaks?
We’ll have to wait until the moon isn’t so bright and see what we can do! Share tips and what we discover, if you are up for it.
I am def up for it.
All right then – looks like we have ourselves a challenge. I’m looking forward to this, it’ll be great to see what we can learn. Should we keep this thread going for the updates then?
That's sounds like a good idea. Lets go ahead and make some suggestions?
Some Defs for me:
Mirror Lock Up
Tripod (Duh)
Rubber Band trick for bulb exposures, stopwatch.
Fully charged batteries.
Maybe make a trip out into the country side?

What technical details would you suggest?
ISO?, apeture?
I agree with all your suggestions, never tried the rubber band trick though.
I always shoot the lowest ISO (200 for my camera) if I’m using a tripod.
I have found by trial and error that f8 – f11 is the sharpest for my lens and this range seems to be the sharpest for most lenses.
I usually use my cameras self-timer to trip the shutter for this kind of shot.
Another trick I use when the exposure is several seconds or more is to hold my hand in front of but not touching the lens when I open the shutter, then I pull my hand away when I’m sure any camera vibration has died away.
If there is any wind a weight on the lens helps to prevent any motion. I’ve heard of people using bean-bags, I’ve used a fat open book in the past.
Those are the fist tips concerned with sharpness that come to mind. I’ll keep thinking.
All my moon shots have been done from in the city. The light polution doesnt seem to be a problem. For star trails I think I'll have to get away from the lights. I'm going to try from the back garden anyway to see what happens. I think I’ll try some from the back garden then go straight out into the country and shoot again just to compare. I’m sure there will be a huge difference – we’ll see.
When it comes to star trails one thing that will be interesting to see is the effect of sensor heating with long exposures. I’ve never experienced this but I have read about it and seen it in other people’s pictures. Different temperatures across the sensor cause what usually seems to be a purple cast to parts of the image. The Nikon has a feature that allows you to take a second exposure with the shutter closed, it then subtracts this “dark frame” from the original image to correct the error. I don’t know if the Canon does the same. Trouble is it doubles the time to take a picture.
I know some people take just one dark frame using their lens cap and use that in post processing to correct the images. I’ll have to read up on this, as I’ve never tried it.
Yep, I couldn't resist taking a shot, too.
I used a remote cable and a tripod but the lens is so long it kept drooping. I finally rested the front of the lens on the fence post.
Man, I just can't stop tonight!
THIRD TRY, I like this one the best:
Yeh, that’s by far the best – well done! So what did you do differently that improved it so much? I see you opened up to f8, did you change anything else?
Some super moon pics have been posted while I was in bed. Unfortunately it was overcast here. I’m keeping my fingers crossed for tonight.
I think I was screwing up the exposure in RAW, so I shot the new set in JPG so that'd be set. Yea, f/8 was used and I was more careful with post processing. It was an ugly color so I converted to b/w with a little of all the rbgs as needed. And all the little misc. editing. But, it all couldn't have happend if I hadn't have started out with a good focused pic.
I can't wait to try another shot tonight ... right now it's very overcast here ... sure hope it clears up! I've quickly become addicted to the moon since I've read this thread and now know how to get good clear shots!

Go for it, I never thought shooting the moon could be so interesting until I actually tried. It was challenging getting the right shot and I had a good time with it. I am also going to try and reproduce my results tonight if the sky stays clear.

That’s great Pamelasue! I look forward to seeing more of your moon pics. As jfriesen said, it’s an interesting subject and takes lots of care and good technique to get a really great shot.
Mike.
