MDM Observatory 2.4m Telescope Observing Report for 2011 Jan 24 Observer(s): Julie Skinner Institution(s): Dartmouth College Instrument: Modspec+Echelle, Retrocam Worked for 13 hours (all night) Conditions were Mixed most of the night. Problems were encountered, see the separate trouble report for details. Seeing and Weather: Beg: Clear, Winds Light & Variable Mid: Patchy Clouds, Winds Moderate End: Patchy Clouds, Winds Calm Observing Summary: Shortly after Bob left this afternoon, echelle started having charge transfer issues. I opened at sunset and attempted once more with a band star and comparison spectrum. Line profiles still did not look right, so I switched over to Retrocam. Retrocam was a mixed bag. It worked perfectly, but for it to be in focus the guider could not be in focus. I inspected the coarse adjustment for the guider focus as described by JT in a phone call, but was not confident enough that I wouldn't screw something up by trying to move it. Thus, image quality was poor to mediocre due to guiding errors, as well as the patchy clouds. ------------------------------ Submitted on 2011 Jan 25 [7:10:49]
