Might as well jump in with both feet.

Hello all. I like this site and hope to learn a lot. So, to start with, tonight I made an attempt at a long exposure to get a picture of venus, jupiter, and the moon lined up in the western sky. mode=m, Tv=10 sec, Av=3.5, iso=1000. But, as you can see, the moon is overexposed and totally blown out. I still think it's an interesting picture but know I can do better. If anybody's got a suggestion as to how to do that please let me know.

Welcome LDM5. I think you will like this place.
That is an interesting photo and a difficult subject to capture. I took one like it Saturday night and exposed for the moon. I had to adjust in photoshop to get Jupiter to show up at all.

Welcome!

Blown out moon or not, I agree that it's a great photo with a lot of interest. Your biggest problem is the brightness of the moon exceeds that of Venus and Jupiter by a range greater than the dynamic range of your camera. A properly exposed moon would barely show Venus and Jupiter would be too dim to see on the image or would show up as a couple of faint pixels.
There is a 10 magnitude (the brightness scale used by astronomers) difference between the illuminated portion of the moon and Jupiter which means the moon is about 10,000 times brighter than Jupiter.

Welcome to the forum. For what you are trying to do, you may have to stack multiple shots. I've never gotten it to work too well and I blame it on the fact that I don't have the mount that moves the camera synchronously with the earth's rotation. Registax is the software that's been recommended to me if you want to give it a try.
Good luck and if you get it working reasonably well, please let me know how you did it!

Thanx for the input. I kinda figured that the brightness of the moon was the problem. Guess I can't get the photo that I was hoping for without some fancy pp (which I'm not very good at). Understanding layers blows my mind like the moon in that picture !

I love the photo just the way it is! Great picture!

The question you didn't answer was what kind of photo were you looking for? Frankly, I think the image that you got was excellent and the moon - overexposed and all - added a lot to it. For an image showing the 3 brightest objects visible in the nighttime sky it's pretty impressive!
If you want to get detail in the moon, there ain't no substitute for focal length. These were taken with a 2000mm f/10 cat system.
