Description

Petite nébuleuse dans Persée ressemblant à un écureuil , avec un petit amas d'étoile que je ne connaissais pas. La luminosité de l'objet est très faible, d'ou les vingt heures de poses nécessaire.
On peut aussi apercevoir la petite nébuleuse planétaire OU1 découverte par Nicolas Outters en bas et au centre de l'image à coté de l'étoile brillante ...

Small nebula in Perseus look like a squirrel, with a small cluster of stars that I did not know. The brightness of the object is very low, from where the twenty hours of poses necessary.
We can also see the small planetary nebula OU1 discovered by Nicolas Outters at the bottom and in the center of the image next to the shining star ...
