Hi BMD,
I think the information you want on the OI display is on the Apparent Data tab. It's called the Altitude above visible horizon, shown here for Venus: [attachment=2095]
Note the difference between this altitude & the True Altitude. As objects approach the horizon the difference between these 2 altitudes will increase. You can check it out on a crescent moon.
Again, a superior explanation by Greg.
Hope this helps,
Phil S.
