No cloud onset detected. The transparency index held at 100 (IQR 93–112) across 40 light frames. Guiding held at 0.66″ RMS (RA 0.47″, Dec 0.46″) over 3.8 h; the worst minute was 1.97″ at 22:44.
100 = that target and filter's own clear‑sky median (this night's own pre-cloud median). Shaded columns are autofocus runs; the first target is named at the top left and dashed vertical rules mark each target change; ticks along the base are errors.
Mean luminance of the upper sky per all‑sky still — independent of anything N.I.N.A. recorded. The camera auto‑exposes, so this is an instrumental number, not photometry.
RMS tracking error per minute from the PHD2 guide log, taken about zero rather than about each minute's mean, so slow drift counts as error. 4821 guide frames over 3.8 h of guiding in 10 sessions; the gaps are slews, dither settles and autofocus runs, when PHD2 was not guiding. PHD2 discarded 63 further frames — usually a lost star. The worst minute (1.97″ at 22:44) is clamped at the top of the plot.
The divisors behind the index — median detected stars per light sub.

Star counts come from Hocus Focus detection on each saved sub, tagged with the filter in place at exposure start and the target then being imaged. Frames inside completed autofocus runs are excluded. Still capture times come from the AllSky filenames. All times are local.
