I agree, looks very helpful and LOTS of fun!

I especially liked the monthly Deep Sky Calendars - click on the object and it pulls up more info and a Finders Map that shows the location in the sky for that object. Also you can set your location, and it tells you what you can see, and where and when to look. You can set filters to narrow down the type of sky objects you'd like to see, or the type of equipment you are using - including naked eye. Genius and easy to use.
