Problems were encountered, see the separate trouble report for details. Seeing and Weather: Beg: Clear, Winds Light & Variable Mid: Clear, Winds Moderate End: Clear, Winds Moderate Observing Summary: A beautiful night; got lots of good data. A few first-night glitches; actual problems were fairly minor (see report). The telescope focus changed substantially (upward by 100 units) as the temperature dropped; hopefully I have the focus temp. compensation set up correctly. ------------------------------ Submitted on 2023 Dec 8 [7:06:29]
