Hi Trent
As this is your first step into AP, might I suggest that you use this as a learning experience, you have covered most things, make sure you have all your cables and methods of attachement, eg T-Rings sorted, there will be 240 v power available on the Tennis Courts where we will be setting up. I don't know what sort of scope or camera you use but if it is in the Canon EOS range, there will be a number of people using them.
Dew will be an issue so make sure you have, at the minimum a hairdryer of some sort. I take it you will be hand guiding.
Don't worry about being your first step into AP, there will be plenty of people to give you a hand and get you started.
Just turn up at the Tennis Courts and we will give you a hand.
See you there
Cheers
John G
