NGC 2261

It was Hubble who first noticed the changes in the nebula in photographs. The object changes in brightness and shadows in the structure of the nebula. The changes occur over weeks and months. The best theory explaing it, is dense knots of dust streamers cast shadows on the reflection nebula. The nebula is illuminated by the star R Mon, which is a young Orion type star. It is an irregular, eruptive type of variable star that can vary as much as 2 magnitudes in brightness.


Imaged with a 10" RC scope and ZWO 1600MMC camera.
