Example from TheSky6 attached.
EDIT: Yeah, I had crummy horizons at my old house.

I've never gotten through the whole process, but would love it if there was an easier way. How difficult was it to setup in the Sky?

And others, I'm sure.

Adam - in TheSky you just entered alt-az coordinates for the horizon limits in pairs. I did every 5° of azimuth. So it was a bit tedious, but not bad.

If you connect a computer controlled scope to TheSky ... you can set the horizon limits with greater accuracy and far quicker than using the manual input method.
Just open the "Telescope" menu ... "Link" your scope ... and open both the "Telescope Line Editor" box and "Motion Controls" box. Next, slew to the horizon using the motion control keys ... click-on "Horizon Line" and "Continually Follow Telescope" in the Telescope Line Editor box. Then, just scan 360º along the horizon using the motion keys ... while looking through the main scope or finder ... and the local horizon will be automatically drawn in TheSky display. Save it and you're all set! You can also save local horizons for many different locations. Great tool ... great program.

To my knowledge, no program yet has a related feature to allow you to define (at least one) "sweet spot" in the overhead sky for planning observations, although I suppose you could "edit the horizon" in such a way to eliminate less desirable parts of the sky.
Likewise, I am not aware of any program that allows you define and eliminate an area near the zenith, which can be problematic for Dobsonians and longer FL refractors.

If you have an iOS device you can use Observer Pro to measure your horizon and visualize it against a large database of objects (I had a similar problem which is why I created Observer Pro in the first place). It's been way too long since I've updated it but I'm finally working on an update now.
