Sky Background et SQM

Recommended Posts

Bonjour, en utilisant le soft Astrometrica on a dans le log une indication "Sky Background" exprimé en mag/arcsec carré. Est-ce bien la valeur que l'on nomme SQM ?

Merci

Je veux dire: est-ce qu'on peut comparer la valeur de fond du ciel que me donne le soft Astrométrica" avec la mesure que me donnerait un Photomètre Sky Quality Meter ?
