Yes, I was really on the fence about this, but when I didn't get a
STUI messenger response from you on New Year's eve, I wasn't sure you
would be available on the holiday. So I decided to stick with the
stable version. I should have sent you an email to double-check on
your availability.
I would prefer to stick with v6_6_1 tonight, so we can put our
attention on making sure the work done to the telescope today is
stable. We can run your test version tomorrow, if you' are available.
