This is a great program and does a lot of things. I find it's asteroid and comet plotting functions very useful. The ability to plot virtual observatory data, interface with SAMP, and control ASCOM equipment are some of the things that make this program as good as (or better than) professional programs.
Well designed and good locking feature of its kind, but a lot of bugs in user interface!
Great app, though there are some bugs in UI. But I am impressed of close views of planets and Moon.
