Love how this has evolved into such a versatile and feature rich program With both 32 bit and 64 bit support, just love it. Download button is for 64 bit but "Browse All Files" Link under button will get you to 32 bit :-)
i first used this program several years ago and i just installed it on a new computer after not using it for a while. this is such an amazing program! i find it so easy to use, it has a great user interface, and so comprehensive in its features. and it's free!!! the only thing i've found that could be improved (i'm not astronomer) was setting your current location. if there was a way pan/zoom on the map (link it to open maps or google maps) so you could select your position, that would be great. in the meantime, i'll cut/paste lat/lon from google earth. donation made; keep up the great work.
Incredible software with one serious drawback: It needs text entry, search, map zoom, etc. on specifying viewing locations. It takes way too long to scroll down to "United States of America", for example. The location map is almost uselessly small and needs zoom/select capability. I apologize if these functions are already user-selectable and I haven't learned how to change them, but it's not for lack of looking through the Settings options; I just don't see it yet.
Best app ever!
One of my best apps ever !!
