When I observe planets I will spend anywhere from 1-4 hours on it (with breaks) easy
30-40 minites at a time, especially o'l Jup's where you have lots of action to
observe.
I cant do that with my UO HD, because lets face it, as good as they are
they're not real comfortable to use for extended periods of time. I think you
can guess where my comfort lays, still that comfort comes with allot more
dollars. I think of premium ep's like this you buy them to keep for life, they're
an investment not only in resale but in pleasent observing sessions. That's
the way I see it. And that not to say that someone esle dosn't get the same
pleasure from their UO HD... I just cant use them for extended periods.
