Description

The Rosette Nebula (NGC 2237) located in the constellation Monoceros. This is only a few hours of data, but I couldn't wait to process it to see what came out. Was very pleased with the HA data, but the OIII and SII left me a little underwhelmed. Will go back at it again tonight and try for more of everything, plus so LRGB stars, to boot.
