I have now used my little tool to evaluate the brightness of T CrB in real-time with a Seestar S50 smart telescope (and sound an alarm to wake me up in case of an outburst!) for more than 20 clear nights, some with rather challenging intermittend clouds) and I’m now confident enough to recommend its use by others.

I still need to correct many typos in the documentation files README.md and Adv_Documentation.md (which were written in a frenzy to outrun T CrB going nova…) but the scripts themselves are stable.
I’m still looking for people who want to give this a try with the newer Seestar S30 product. If someone wants to port this to Windows, that would also be most welcome (it’s currently intended to be hosted on a Raspberry Pi or other Linux host).
