Problem(s) Encountered:

OWL does not seem to be communicating properly. ds9 isn’t automatically loading (and so multiple exposures isn’t working), and clicking the ds9 icon in OWL resulted in an error. Of more concern is that the controller temperature reads 000.0. I tried restarting OWL but the result is the same. Humidity forced close tonight anyways.

Solution:

Restarted Owl and all seemed well. Temperature is well below -100 and a 1s Ne shows lines as expected.
