8,920 HYG catalog stars at magnitude 6.5 or brighter fill an Aitoff map. Position shows right ascension and declination at epoch 2000.0; no current observer location is implied.
Dot area follows apparent brightness above a 0.5-pixel minimum; selected stars are enlarged. Color approximates B−V, with neutral white for missing values. Arrows step bright to faint; hover reads the record.

Magnitude 6.5 is a conventional limit, not a visibility guarantee. No viewing conditions or proper-motion updates are modeled. Distances convert parsecs to light-years; the catalog’s unknown/dubious values are shown as unavailable.
