Thanks Paul for the quick reply.
I had quickly looked at it but obviously didn't spend enough time learning what it could do.
Now I know, I'll invest more time in working out how it can help me.
Thanks a lot again.
It is discouraging trying to work out the answers to the millions of questions that come up learning about astronomy from first principals and help from people who have already worked it out really saves a lot of time that I would prefer to spend looking through my scope and/or doing things with my 5 year old son.
