Thanks Mike, that looks great and I might buy two at that price just in case I drop one or something.
I have not had the chance to check out Pixel Fixer as yet as I am now back at work and time is against me again. I would really like to use darks as my camera tends to get some horizontal banding during long dark exposures, so I'll just keep chipping away at it.
I have tried to put toghether a few time lapses and will load them to the net when I can get it all sussed out with a format for the net that isn't 200mb.
