Rosetta Nebula and NGC 2244

An object often photographed, but I've never had a go at it before and as clear skies have recently coincided with near full moon I needed to shoot a region with a lot of ionized hydrogen. Inside the Rosetta Nebula sits the 5 million year-old open cluster NGC 2244. The cluster and the nebula are around 130 light years in diameter and roughly 5200 light years from earth.
