Raggie, that's not too bad. Mine is somewhat similar in nature at 320mm which is the highest my zoom will go. I used a tripod and tried all sorts of different settings until I found the one I liked. In my particular case I kept the aperture locked at F8 as that is the sweet spot for the lens and played with the shutter speed. You really need a nice telescope with a camera mount.
