This is the first image I have taken using a H-Alpha filter. The H-Alpha filter is designed to cut out almost all wavelengths of light other than the hydrogen iteslf. In this case the hydrogen in emmision nebulae is exactly what we want to tease out in the picture. The Rosette Nebula is located in the constellation Monoceros. The cluster and nebula lie at a distance of some 5,200 light years from Earth (although estimates of the distance vary considerably) and measure roughly 130 light years in diameter.
