What about a funnel attached to a flexible rubber hose out the zipper of the tent? Well now that i think about it, you can go #2 your way much easier then trying to sh*t through a funnel.
i use the Swaro universal tripod adapter. I know they make similar ones for cheaper, but that might be an option for you to attach your glass to a tripod.
I use Browning and Stealth cam. Both have been great to me. I will +1 on putting them higher in the tree to minimize thieves from seeing them and bears from chewing on them. I lost 4 of them to bears last year.
