Something to keep in mind though, in order to do this the way it SHOULD be done, there needs to be electricity. My big scope is computer controlled & the 5" has a clock-drive on it. Ideally, I would need to have my laptop there & I could give some basic examples of how we image through the scopes with digital cameras & CCDs, & then stack & process the images on a computer to make them really cool.
Strictly visual observing is fine too. But modern technology has made imaging VERY quick, simple, & just hugely interesting to watch happen. The scopes CAN be operated from a big rechargable battery pack. But I only have 1, they are expensive, & it wouldn't last very long if I had 2 scopes, dew heaters, & the computer hooked to it.
All this stuff can also be operated from a cigarette lighter. But once again, multiple equipment would run the battery down quickly. So you'd have to leave a vehicle running at least part of the time, or use just 1 rig to 1 piece of equipment, so there was little drain on the battery.
A generator is a definite no-no. The electricity they provide is much too "dirty" to trust with a mount which costed a couple thousand $$$'s. So in order to do this the right way, for convienience, simplicity, & max enjoyment, we'd need a place that we could arrange to hook up to electricity. State Parks LOVE star parties.....they do them on Pinnacle several times per year.....so they already understand what is needed to set one up.
But, of course, there's always just purely visual peeking through the scopes, story-telling, & using a laser to point out objects in the sky. That doesn't require electricity, but takes away half the fun & works the heck out of whomever is controlling the scopes. There's no computer to help out, so the operator has to rely on paper, charts, manual setting circles, & mathematics to find the targets.
But it CAN be done that way. Electricity just makes it so much easier & adds a ton of stuff to what can be included as an activity.
