Hi Adrian,
with planets in particular it comes down a lot to 'the seeing'. you may have noticed Jupiter kind of going from sharp to blurry randomly due to the atmosphere, lastnight was very windy so i'm sure you'll get a better view with better conditions. the better the seeing the more of the sharp view you will get and less the blurry.
when it comes to the photos they are usually done by videoing the planet and then passed through a computer program to remove the blurry moments and then the sharp ones are stacked to reduce noise.
