this exposure was substantially affected by very thin high cloud on friday night/saturday morning, but you wouldn't necessarily know it looking at the result:

will have to go back and study up more on getting 'accurate' colour, as my default channel scaling based on a previous G2V star measurement didn't get close. so this is aesthetic rather than scientific colour for the moment..
