Per la corretta visione delle immagini astronomiche è opportuno regolare contrasto e luminosità del monitor in modo ottimale.

Il monitor è ben regolato quando il bianco è brillante, il nero è un nero che fa paura, e si vedono tutti i grigi uniformemente distribuiti. Se non ci riuscite ritornate con la mente al giorno in cui avete acquistato il monitor: siete ancora convinti che fosse un buon affare?
