Hover a point for the Seestar serial, date and V. Open circles flag frames with a poor zero point (calibration RMS > 0.05 mag); use Grey out poor ZP to de-emphasise them. The grey star is the discovery epoch. Highlight a single Seestar with the dropdown; scroll to zoom and drag to pan (Reset zoom restores the full view).

Each point is one frame's own zero point (error bar = that frame's calibration RMS against Gaia), coloured by Seestar — every epoch is calibrated independently, across nights, units and sites. Open circles flag a poor zero point (RMS > 0.05 mag); use the controls to grey them out, highlight one Seestar, or zoom (scroll) and pan (drag).
2 · Calibration Each stack is reduced independently, so heterogeneous Seestars self-calibrate:
Source extraction — SEP background subtraction + a chromatic fixed aperture (per-band 90%-enclosed radius) on the R/G/B planes.Astrometry — the CrowdSky-solved WCS is used directly (re-solving with astrometry.net is available as a fallback).Zero point — green instrumental mags are fit independently per frame to Gaia DR3 synthetic Johnson V over V∈[10,14]: V = m_inst + ZP + k·(B−R).Host-galaxy modelling — the SN sits ~28″ from the bright NGC 3310 nucleus; the host flux in the SN aperture is estimated empirically at the SN's galactocentric radius (azimuthally, away from the SN) and subtracted.Forced photometry — the fixed aperture is measured at the SN's known position, giving the galaxy-corrected V.Zero-point calibration for the latest epoch — a representative example only. Every epoch is calibrated independently against Gaia; each epoch's own ZP, star count and RMS are in the per-epoch strip above and the credits table. Host-galaxy contamination geometry for the latest epoch. Latest epoch (2026-07-23T04:30:53.071, 955f8f85): ZP = 21.146, calibration RMS = 0.081 mag over 11 stars; host contamination ≈ 25% of the aperture flux (raw V 11.29 → corrected V 11.61).
