What size telescope were you using, and what were the students looking at and photographing. How many students in the class, and how much observing time did they each get? And is the light pollution in Portland bad enough so that they actually get a lot better viewing in Bend with a smaller telescope than doing in on campus, or is the camping and shared group experience really more the real benefit of the remote expedition? In any case, sounds like a great idea!
14" diameter telescope and yes, sooo much better in Bend. It's hard to even see galaxies at all in Portland, the sky is so bright. In Bend, I became a bit lost in the sky at times because there were just so many more stars to look at!
There are 20 students in the class, one opted not to go on the trip (did a project do-able from Portland) and they were in groups of 2-3. The groups each got 2-4h on sky.
But yes, the camping + experience is part of it - get them outside the Reed/Portland bubble!
