Subject: 2.5m obslog 20210730 (SJD 59426) From: doravetz@apo.nmsu.edu Date: Sat, 31 Jul 2021 11:43:38 +0000 (UTC) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday July 30, 2021 (SJD 59426) ---- Observing Team ---- Dylan Gatlin Dan Oravetz Kaike Pan Ryan Wagner (remote help) Tracy Naugle (remote help) ---- Observing Plan ---- Optical collimation and fiducial data collection if we can't observe. ---- Observing Summary ---- We battled clouds and radar returns the majority of the night and then humidity towards the end, but we still were able to get a good start on shakedown. We completed the home/relax mirrors procedure and the position errors were all acceptable. We got the engCam alive and talking and re-routed the power and ethernet cords because they were prone to get in the way of the stage motion. We took grid and ring data and updated the engCam instrument block. We made a first pass at optical collimation in-between clouds - we determined that xtilt = 35 arcsec and ytilt = 12 arcsec is a good starting point for when we resume optical collimation under better weather conditions. Notes ===== - Instrument lift controller display is showing incorrect values. - With the new corrector, we found 400 to be good counterweights for the engineering camera. - Left telescope ventilating for Kaike to collect fiducial-crossing data this morning. ---- Observing Log ---- 00:20Z Started ventilation. It's very early, but it was cooler outside due to rain during the day. Loaded the engineering camera, set new counterweight values to 400 after repeated tests. The balance was excellent from 30-60 but was a little off beyond 70. Overall it was very good. ================== Home/Relax Mirrors ================== ------- Primary ------- Starting M1 setmir orientation: 0,0,0,0,0 desOrient=0.00,0.00,0.00,0.00,0.00,0.00 desEncMount=10450.00,-1100.00,6850.00,19700.00,8500.00,8550.00 home E,F: "position error", "999999999, 999999999, 999999999, 999999999, 000000000, 000000000" home D: “position error", "999999999, 999999999, 999999999, 000000000, 999999999, 999999999” home A,B,C: "position error", "000000000, 000000000, 000000000, 999999999, 999999999, 999999999" Returned M1 to original setmir orientation: ‘move 0,0,0,0,0’ and verified actual reported orient values match the desired/commanded values.

The 12V Distribution Box on the rotator needed to be toggled ON, but that was the only hiccup. Verified the engCam stage moved as commanded. Darks look good. A 50s flat produced ~38k counts median. 03:45Z - Waiting for radar to move out and weather to improve. 05:05:56 - Opened. gimg-0016: RA offset +50 arcsec, Dec offset +180 arcsec puts the star in the center of the CCD. gimg-0030: best focus was -30um, resulting in seeing of ~1.5-1.6 arcsec FWHM. gimg-0047: the star is about in the center of the CCD. ecam_star=47,246.92,247.44,3.141,28.42,42351.6 ===================== Instrument Block Data ===================== gimg-0048 ==> START OF GRID DATA Updated the instrument block file with the new scale and orientation. 06:39Z - Another focus loop. gimg-0110: focus=-20 um, seeing ~1.1 arcsec FWHM. gimg-0115 ==> START OF RING DATA Updated Rot_Inst_xy in instrument block file. Started taking another set of grid data with the newly-updated instrument block. gimg-0158 ==> START of SECOND GRID DATA NOTE: Lots of points were missed because of clouds, so this data set is not particularly useful. =================== Optical Collimation =================== We decided to start looking at donuts just to get a feel for the tilts. setmir 0,35,15,0,0 looks pretty good at first glance. See images gimg-0241 (foc=280) and gimg-0242 (foc=-320). 08:30Z Focus loop: gimg-0254 has FWHM of 2.660 pix, ~ 1.1 arcsec FWHM. Now applying the XTILT=35 and YTILT=15 and checking FWHM of an in-focus image. gimg-0259 now has an improved FWHM of 2.573 pix. gimg-0286: donut looks pretty good; foc=-570, xtilt=35, ytilt=12 gimg-0296: donut looks pretty good; foc=430, xtilt=35, ytilt=12 1-deg off center ================ Took awhile to focus off-axis and humidity and clouds were chasing us away. gimg-0421: Foc=330 um; xtilt=35, ytilt=12 gimg-0422: Foc=830 um; xtilt=35, ytilt=12 1.3-deg off center ================== Another focus loop. Foc = 370 um determined to be the best. gimg-0440: Foc = -130 um; xtilt=35, ytilt=12 gimg-0441: Foc = 870 um; xtilt=35, ytilt=12 11:35Z - Closed. Stayed ventilating for fiducial-crossing data. ---- Mirror Numbers ---- Took a set of mirror numbers for reference after completing the home/relax. We didn't bother saving new NOMINALS because they'll change after collimation anyway.
