NGC 2237 – The Rosette Nebula in Narrowband

Presented here is a 4-panel narrowband mosaic of NGC2237, the Rosette Nebula.  From Wikipedia :

The Rosette Nebula (also known as Caldwell 49) is a large spherical H II region (circular in appearance) located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open clusterNGC 2244 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula’s matter.

The cluster and nebula lie at a distance of some 5,000 light-years from Earth[3]) and measure roughly 130 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses.

Over 55 hours of total integration is shown here, in the traditional Hubble SHO Palette, as well as a “natural” blend.

    I’ve been following you log for a while now, and finding it entertaining, educational and enjoyable- a tricky combo to achieve!

    The Rosette imagery is astounding- beautiful work!
    I was wondering what progress you’ve made on the Dome Project? I was floored by the idea of the giant planetary gear to turn it and plan to use it on mine also- great thinking indeed. I want to try putting the shutter onto a vertical gear segment for raising and lowering too.

      Thanks for the kind words, Neville!

      The Dome Project became the Roll Off Roof Project. 🙂 The dome proved to have too many “Yeah, this works in the shop, but once it’s outdoors I’m not so sure…” things going on. Many years of RC airplanes has taught me it’s better to punt then, rather than up in the air. *lol*

      I’d like to see your work on a vertical gear segment for the shutter!
