Hi Darryl, welcome to TSP! I can answer some of your questions.
I am not an imager but can offer some perspective as a visual observer who shares the field with imagers.
1. Wifi. Not sure what the rules are. The concern is that all the wifi signals on the field will interfere with each other. Somebody else chime in here.
2. Small tent... Depends on which field you set up on. If you are in an RV and want to observe near your RV, then you'll be in the RV field which I know little about and others with experience there can offer advice.
What I can tell you is, if you choose to observe and image on the upper field, tents are allowed but must be in the outer boundary area outside the marked perimeter of the field. Many imagers set up a table and laptop station rather than working from a tent. Please if you do this, please use a dark filter over your laptop screen, point your screen away from the middle of the field, and use a deep shroud so your neighbors don't catch an eyeful of light. Most imagers are polite and really try to shield their light but overall the upper field is getting brighter every year with screens and various LEDs, etc.
3. There is a grid of power cords on the upper field (and middle field?) for powering telescopes.
4. Cell service is hit and miss. Depends on your provider. There are various magic spots on the ranch where service seems to work. Don't count on it though.
5. Be prepared for wind, sun, and dust devils. Stake your equipment down and store delicate stuff out of the weather during the day.
TSP is great. You'll have a blast!
Hey Kurt!! I was hoping to make a return to TSP this year since I have not been there since 2018, but life has gotten in the way. I miss TSP like crazy. Maybe next year or Okie-Tex.
