this is my first post here after weeks of reading and viewing. i really like your site. here is my dilemma, for weeks i have been trying to shoot the moon. well i've got the exposure down, just not the focus part. i'm using a 70-300mm lens. i can't seem to get the moon in focus. yes i've got a tripod and a good one, and yes i'm using a remote release. shooting at the "sunny 16" theory. my D50 only has a ISO of 200. i tried a 2X teleconverter and still i'm can't seem to get it right. please if you have any ideas i would love to have them.

Laurie,
I can't really tell how good your resolution is from the low res web photo, but I'm sure you are probably getting the optimum image you can from your setup. Unfortunately, I can tell you from experience that you don't really have the optics to get the resolution you want. A 70-300mm lens on a 6mp sensor just won't do it (even with a TC). On top of that the full moon is especially hard to capture because of the lack of shadow detail. Here is my best effort using a Tamron 600mm mirror lens, 1/30", f/13 on a D200 body (10mp sensor) with the mirror locked up and a very good tripod. It'a also about a 50% crop. Shooting the half moon at least lets you get some crater shadow detail at the horizon line.
The best moon photos I've seen always come from astrophotograpy with a telescope. If you are really interested in astronomical photograpy, that would be the way to go.
Hope this helps.

My first thought after viewing your images was that you didn't have your mirror locked up. The second thought is that most photographers consider shooting the moon as a daylight exposure. ISO 100 - 200, F 8 - 11, and around 1/30 - 1/60 shutterspeed. After reading your explanations my second thought might be the infinity focus on your lense. May you need to back off of infinity a touch. Just some thoughts. www.bsvirginian.smugmug.com
