| =====Log===== | =====Log===== | ||
| + | - Normal start-up procedures | ||
| + | - Moved to Procyon | ||
| + | - Focusing | ||
| + | - Starting Focus: 2611.4 | ||
| + | - Ending focus is 2611 | ||
| + | - Achieving 15-17 pix FWHM | ||
| + | - using phd2 autoguiding with RA tracking rate of 15.011 arcsec/sec | ||
| + | - after we turned on autoguiding, | ||
| + | - saving all data to internal Z drive | ||
| + | - On Procyon | ||
| + | - using subarray 1200x250 pan 48, tilt 914 | ||
| + | - bin 1, mono16, .ser files, gain 279, brightness 40 | ||
| + | - 2 sequences of 120s each in u and g filters, taken before timing calibration | ||
| + | - sequences also taken without .CameraSetting files | ||
| + | - Moved to Venus | ||
| + | - Note, needed to disable autoguiding between sequences to adjust source in frame. Venus does not move with stars, so PHD2 guiding on stars doesn' | ||
| + | - For all: TurboUSB at 100 (auto set to OFF) and High speed mode off | ||
| + | - U filter | ||
| + | - using subarray 1600x800 pan 48, tilt 640 | ||
| + | - bin 1, mono16, .ser files, gain 279, brightness 40 | ||
| + | - 2 sequences of 120s each in u filter, taken before timing calibration | ||
| + | - have .CameraSetting files | ||
| + | - G filter | ||
| + | - using subarray 1600x800 pan 48, tilt 640 | ||
| + | - bin 1, mono16, .ser files, gain 100, brightness 40 | ||
| + | - 2 sequences of 120s each in g filter, taken before timing calibration | ||
| + | - have .CameraSetting files | ||
| + | - Z filter | ||
| + | - using subarray 1600x800 pan 48, tilt 640 | ||
| + | - bin 1, mono16, .ser files, gain 200, brightness 40 | ||
| + | - 2 sequences of 120s each in z filter, taken before timing calibration | ||
| + | - have .CameraSetting files | ||
| + | - Another 2x120s in U | ||
| + | - Same settings as above | ||
| + | - Slewed to LAWD 73 (GrW +708247) | ||
| + | - We expect this to be too dim to see with $12\mu s$ int time, so we slewed to something we could see (Polaris) to ensure pointing was correct. LAWD 73 is 13 mag, so we didn't want to just do a long exposure with the sky getting bright | ||
| + | - We call this process "Going In Blind" | ||
| + | - AND the SIMBAD ICRS RA & DEC were based on J2000, not J2023.5 (DFMTCS) | ||
| + | - We slewed to Polaris in J2023.5 | ||
| + | - Then trusted that J2000 --> J2023.5 didn't change much with a proper motion of LAWD 73 at ~80mas/yr | ||

| =====Notes===== | =====Notes===== | ||
| + | * With ASI 178 pixel scale at $2.4\mu{m}/ | ||
| + | * Using DFM TCS and TS6 to give slew commands allowed scope to bypass limits on RA movement | ||
| + | * This led to wires beginning to wrap -- we need to pay attention to this in the future | ||

| + | At end of night | ||
| + | - 9C in Dome | ||
