The Rosette Nebula (also known as Caldwell 49) is a large, circular H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 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 and measure roughly 50 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.

This is a total of 40 hours worth of exposure each exposure being 30 minutes long.

I won't go into the usually superlatives its just enough to say that its a stunner as usually, well done Sara

As above...simply stunning!! I shall check out your Flickr stream ASAP.
 
Excellent, thanks for sharing ;)
 
Thanks yet again for sharing your images, Sara. Another stunner.
 
This is incredible.
How do you create such images? I dont quite understand how you can take 80 x 30 minute exposures and piece them all together. surely everything moves slightly?

The mount that I use tracks the star target all night and for subsequent nights the software put the target in exactly the same place on the camera sensor.
 
The eye of sauron is always watching...

Just thought I'd post up to say I'm still enjoying your images too.

wow thats incredible, not something i could achieve with my equipment!
 
It's really quite specialised, the kit, knowing how to use it. Then the patience, the weather and finally the processing. Such a specilised subject but the images you produce are amazing.

Quoted for truth!

The kit bit's relatively easy - with sufficient funds and a list! The rest is far beyond me so I have to content myself with looking at (and forward to seeing) Sara's results.

I think that you'd probably be surprised at what you can achieve with modest kit........ In my opinion about 80% of the image is in the processing..... 20% is getting decent data to work with :)

You're not wrong, the kit really is quite specialised....... :)

Thanks guys for your kind words - I really enjoy being able to show people what's up there :)
 
As always Sara your posts never cease to amaze me, they look as if they came from a Star Trek movie but please don't take that as disrespect, they are truly works of art.
 
Interesting as BBC2 showed a similar image tonight and was nowhere near as good, simply stunning as always. The consistency of your images is amazing.
Any chance you could post up a single image i.e. just 1 of the 80 so we can see how much the multiple shots add to the overall image. I am just starting astrophotography so would really appreciate how much multiple imaging adds to the end result, thanks in advance.

Can i point you to an article I've written on my website with differences between exposures? I don't have anything at the right size for posting here!! http://www.swagastro.com/my-guide-to-image-capture.html - There's quite a bit of info on there as well if you are just starting out :)

Thanks for the comments guys - I'm glad that you like it :)
 
Just came across this thread.
Stunning image!
Great article too. Thanks
 
Beautiful!

No other words for it really!
