Conditions were good and there were no mechanical or software issues. Around midnight I found that I was unable to find any guide stars I chose. Spent a great deal of time trying to figure out that issue. May have figured it out right at the end of the night, but will need to see tomorrow night if in fact that's true. Clouds appeared around 1 MST and stuck around for an hour or so. Rest of the night was a mix of clear skies and clouds. ------------------------------ Submitted on 2017 Sep 14 [5:31:07]
