Impressive!!

It is handy to have for planning when I am not near my desktop computer, and helpful in the moment while stargazing and looking for other objects than what I wrote down. The coordinates are available for more objects than I will ever see. It shortcuts the time in finding a specific object using the compass feature. I needed the ability to find Polaris through trees, rooftops, and other obstacles so I can properly align my equatorial mount and the search/locate feature does that. I suggest reading the user manual and FAQ on their website to get the most from the app. I find certain display items like the equatorial plane, merdian, and RA/Decl grid very helpful, and the red screen is a MUST HAVE item. I also love the ability to change the time reference. If my scope was a GOTO, I would use the scope controls. You get an awful lot for this inexpensive app, made by the same company that does the phenomenal Starry Night desktop/ laptop software. It is worth the money.
