INT Photometric H-Alpha Survey
Télescope Isaac Newton

Le INT Photometric H-Alpha Survey (IPHAS) est un catalogue astronomique de l'hémisphère nord du plan de notre galaxie. Il est réalisé à l'aide du Télescope Isaac Newton (INT) situé aux Îles Canaries, Espagne. Le catalogage utilise deux filtres photographiques et un filtre H-alpha étroit pour obtenir, notamment, des images de nébuleuses situées dans notre galaxie.

Les observations s'effectuent depuis 2003 et sont presque complétées[Quand ?]. Il sera complété par un autre catalogage de l'hémisphère sud du plan galactique.

Objectifs

Les objectifs du catalogage sont notamment :

Découvertes

Le catalogage a découvert un vaste nombre de nébuleuses planétaires telles la nébuleuse du Collier.
