First, I love SkySafari... I love the Celestron Audio feature.
But, why does the audio cutoff when you center the object?
And, why settle for just the objects Celestron thinks should be described. This program has great description for most planets and deep sky objects. Use a synthetic voice to read the description AND have the description vocalized when it is centered on the planetarium page. That is when you are at the eyepiece looking at the object. That is when ears (audio) can provide a second channel for learning.
Thanks;
