Hi Shane
As none of us can see your image yet it's hard to give you tips. I have a full moon image on my website, which you can find in my profile, that was published in Australian Sky and Telescope magazine last year. That image was taken with a Canon 350D an FD70-210mm lens and a 2 x extender mounted on a Manfrotto tripod.
I also posted an image of the full moon from last night in this forum that you may have viewed. That was taken with my Canon 350D mounted on my 200mm telescope and the resolution and image scale is far superior to that achieved with the camera alone as you would expect.
Anyway upload your image to the site and we can all see it.
What software do you use to process your photos ? Most programs have a method of reducing the dimension of your image to e.g. 600x400 pixels and also compressing them for email purposes etc these days.
Cheers !
