"An impressive astronomical guide"
Seems to contain just about everything an amateur observer would wish for.
It is not quite as intuitive as some other reviewers have suggested, but it is worth making the effort to get used to it.
This accesses an extraordinary amount of information, and as such it is a bit more complicated to get the best out of it. The "Help" section includes a very useful "user guide" (98 pp I think) and I strongly recommend you download this. Once you have come to grips with this, you have a remarkably powerful application for, well, free. Magnificent value!
