Went through start-up procedures - Moved dome so that sunlight wasn't heating-up dome - Needed to reconnect data line for finder scope cam (ASI 2600) - Took flat frames with sky at 1930, scope at zenith - Unsure if 432 is north-aligned, OH WELL - Forgot to record exposure times -- will do this before taking darks, obv - Finderscope camera disconnected (using SC 4.1) - Azzan and Sam went up to reseat the data cable into the Icron - The 2600 worked again, but then disconnected after maybe 60s - Azzan and Sam then moved the 2600 data cable to LBD-2 - Seems to be working -- FOR NOW - Moved to Pollux for pointing -- it was near zenith - Dome tracking is working - Pointing was off - Got some starfield from the finderscope and uploaded to Astrometry.net (thanks to Connor for having an acct) - Waited a few mins for astrometry.net to work - Used the supplied RA and DEC to update the telescope position in DFM TCS - Seems like focus might be off - Went to HD 70272 to see if we can make things better - Started at focus 1919.1 - Optimal focus is 1913.0 - FLATS ARE GARBAGE - DELETING - We Slew to HD 76351 the pointing seem to be off but we re-slew and it fixed the problem ( this is not expected) - Started getting data for Dataredux study - We started the autoguiding software phd2 (we re calibrate it) - Source SA 101 - We took pretty pictures of different objects - We did all the closing procedures (everything went smoothly) - Took darks and flats next day after lecture ~1630-1730 - The sensor temperature seemed a bit too high for the darks, they'll be good for those flats, but we may want to retake darks for the SA 101 light frames ===== ToDo ===== Seeing Targets: - HD 70272, HD 44537, HD 31314, HD 76351 ===== Notes ===== - Data cable for 2600 was disconnected -- we reconnected to Icron - Need to buy new casters for rolly ladder - Need to get Azzan and Sam on Gold Card roof swipe access list - Need to finish set - 2600 seems to randomly disconnect - Seems to be better behaved on LBD-2 for now? - This needs to be investigated ===== Weather ===== | Time | Dome Temp | Outside Temp | Outside Humid | | 1915 | 18 | 20 | 23 | | 2100 | | | | ===== Data ===== {{tag>[seeing mag]}}
