[amsat-bb] Planetarium program?

[Alan P. Biddle]

Hi,

Any recommendations of a good freeware planetarium program, or web site,
where you can put in the parameters of an object such as a comet and your
QTH, and get the azimuth and elevation?  Somewhat off topic, but someone who
saw my antennas asked.  Google of course is very productive, probably too
much so.
