I’m going to Texas also. I have a rental east of Dallas and a friend’s home in Fredericksburg as an option. Have you see this link? It has a lot of interesting stuff and you can compare locations.
I am planning on using EO. I used it in 2017 and had great results. I’m going to try and have 3 computer/telescopes running. I’m hoping to set up the hardware on 4/6 and 4/7. I’m setting up in my backyard this week and doing a practice with all systems. If you have never gone to an eclipse before, take all you supplies with you. Water, Food, Power, Shade
On the EO script, I’m programing it for 2 second intervals. I think the DSLRs will cycle at that rate. I taking the script printout and trying to plug the settings into NINA sequencer. Should work and with the audible from EO I’ll know when to take the solar filters off and on.
On the 2017 I had enough of a cool down during totality that the focus changed slightly. I got some cheep mylar emergency blankets to put around the telescopes this time. They are light and I’ll secure them so they don’t flap in the wind.
The traffic is going to be very terrible. In 2017 the 300 miles from Casper to Riverton was parking lot on both sides of the highway. So don’t plan on getting on the road home until after supper or maybe midnight. That also applies to the day before and the morning of the eclipse.
