Wow, thanks for all the help and advice. I reckon there is plenty there to explore when it is cloudy. I am really pleased that Linux is active in the astronomy field as it has certainly saved 3 decent laptop computers from going to landfill. Linux takes a bit of getting used to especially after 40 years of Windows. For Office programs Libre Office does everything I need and Firefox connects well to the internet. It is a shame that Quickbooks doesn't have a Linux version else I would consider ditching Windows for good and save the need to update the computer every few years.
