MDM Trouble Report for 2009 Jul 7 Telescope: 2.4m Observer(s): Mark Reynolds (UofM) Instrument: TIFKAM Problem(s) Encountered: I encountred both the guiding/tracking problem as well as the dome problem again tonight. The guiding and tracking both became unresponsive at various times, with the tcs reporting the ra/dec to be in GUIDE2 mode. I was able to fix this by aborting my exposure/dither sequence and then manually dithering the telescope back and forth, i.e. 5 south, 5 north or 5 east, 5 west At some point in the above sequence the ra/dec would return to the regular guide-track/idle mode. The dome encoder became unresponsive at the end of the night, I zeroed it once which didn't solve the problem, as it was at the end of the night I manually positioned the dome for skyflats. ------------------------------ Submitted on 2009 Jul 8 [5:32:52] NOTE: This trouble report replaces the previous report for 2009 Jul 7
