Sky transparency — night of 7–8 September 2026

Cloud arrived at 19:22 — detected by the all-sky camera, independent of N.I.N.A. Before it the sky ran at index 94 (IQR 90–98); after it 91 (IQR 64–108). 2 of 86 light frames landed before the cloud. 34 of 34 failures are attributed to cloud. Guiding ran at 0.91″ RMS before the cloud and 0.73″ after; the worst minute was 3.81″ at 00:50. The 22:13 autofocus run fitted its curve on almost no stars and should not be trusted. Morning sky flats: 60 frames (H 20, O 20, S 20), 06:23–06:28, auto-exposure 2.5–5.0 s.

Normalised transparency index, by filter

100 = that target and filter's own clear‑sky median (rolling median over recent clear nights). 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.

H α O III S II ▲ Plate solve failed ◆ PHD2 error

All‑sky background brightness

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.

PHD2 guiding

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. 2232 guide frames over 4.2 h of guiding in 12 sessions; the gaps are slews, dither settles and autofocus runs, when PHD2 was not guiding. PHD2 discarded 291 further frames — usually a lost star. The worst minute (3.81″ at 00:50) is clamped at the top of the plot.

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.
