Description

Grabbed a hasty few hours on another target that is slowly slipping too low in the winter sky for me to image. This is the Rosette Nebula - a highly active stella nursery in the constellation Monocerous (the Unicorn). It's approx 5,200 light years away and spans around 130 light years across. At it's core is a cluster of bright stars (NGC 2244) which formed from the nebula around 5 million years ago. The radiation from these stars is what ionizes the enormous clouds of the nebula and causes them to emit their own, characteristic red (Hydrogen Alpha) glow. Although faint, it's just about bright enough to see with binoculars under dark skies
