No objections what so ever. The more, the merrier, and the cheaper per head it gets when the hat gets passed around for the gift.
If you haven't been to a dark site star gathering, there's a couple of things to note:
* Red light causes the least amount of disruption to our dark adapted eyes. For this, if you just have a white light torch, cover it with three or four layers of red cellophane. This will make your torch light nice and red in colour, and tone down its brilliance
* Bug sprays, such as insect repellent sprays, are a no-no near optical gear of any kind. Not that there'll be many bugs at the Airfield this July, but if you need to apply bug repellent, do so well, well away from the telescopes so none of the spray can waft onto them. Aerosols contain solvents that are very detrimental to optical gear.
* Ask questions! Ask plenty of questions!!! The only "dumb" question is the one that isn't asked,
