Jack, zeners don't "go out" for no reason. It likely saw a transient "event"
that exceeded its rated parameters. They're a poor man's regulator of sorts,
but are usually there only for protection of more sensitive parts of the
circuit. I noticed you were using a ground cover. Lots of folks have found
that the polymer ground covers/tarps can be an ugly source of unwanted static
charges. Probably not good in a low humidity environment with ungrounded and
expensive electronics sitting on top...
Thanks for the peek through that 20". Memorable. (They say you always
remember your first...)

Great times it was! Friday was excellent, and Saturday was exquisite. The 20"
behaved itself this time, the runaway condition of the ServoCat has been fixed,
for the 2nd time back to the shop. Apparently Zener diodes go out every 5
years. Steve gave the sky a 7/8 at its best. I like it when it is so dark you
can't tell the difference with the shroud on or off.
