A Prelude to Winter Deep Sky Objects

A Prelude to Winter Deep Sky Objects
This is an image I took last December 8, but never was satisfied with the results. I've reprocessed it, which I think gave much better results. Unfortunately, the image is slightly out of focus (the bright stars should not have double diffraction spikes), and the object isn't centered in the image. I am hoping to get a much better result this year, as this is on my re-do list.

NGC 2237 - The Rosette Nebula, in the direction of the constellation of Monoceros

The Rosette Nebula is a large, diffuse emission nebula located 3000 light-years away (so large, in fact, that I can't get it all in view at the focal plane of my telescope). The great abundance of hydrogen gas gives NGC 2237 its red color in most photographs. The wind from the open cluster of stars known as NGC 2244 has cleared a hole in the nebula's center.

The Constellation Monoceros

December 13, 2010

We close out 2010 with a look at the constellation Monoceros. This dim constellation, which represents a celestial unicorn, holds no bright stars and is often overlooked for brighter Orion and Gemini and Canis Major. But don’t pass this constellation by. It holds more interesting deep-sky objects than Orion, and gives you many pleasurable moments of stargazing in the waning days of the year.

Monoceros occupies the barren gulf of sky bordered by Orion to the west, Gemini to the north, Canis Major to the south and Hydra to the east. Since it lies on the celestial equator, it’s visible to observers in both hemispheres. Seeing the outline of a unicorn in this dim patch of stars is nearly as challenging as seeing a real unicorn. If you’re in the city, you’ll find it hard to spot any stars at all. The brightest star in Monoceros is magnitude 3.9, and only four stars come close to 4th magnitude.

For those of us who AREN'T Astronomers...a bit of history and info.

And the obligatory Wiki linky
http://en.wikipedia.org/wiki/Monoceros
So now I'll keep an eye out for it here in Oz. Big Grin

Here is a widefield view of Monocros. Note the pink smudge near the center. That is the Rosette Nebula.

Zen was at a place called Koorda (read NO Light pollution) He was totally awed by the "Blaze of stars" and the clear definition of the 'Milky way'

So Monoceros constellation is not visible to the naked eye at all??

Yes, we were there on a night when our bit of the planet was pointing directly at the centre of the galaxy.

Talk about a river of light, it was stunning.

In very dark skies, yes, if you know what to look for. You can also see it in binoculars.
