NGC2237 - The Rosette nebula is a stellar nursery, like the nearby Orion Nebula. It’s located in the constellation of Monoceros. I reused my hubby, Dev's recently created stack of 19 hours & 20 minutes worth of narrow-band data from AUS-2 and SPA-1 telescopes, to create this "new look" for the same old repeated red or blue face of this most popular target in the northern hemisphere.
