Rosette Nebula (Caldwell 49)

After imaging Jupiter on 11/21, I waited until around midnight to start imaging the Rosette.  This is one object that I imaged back in January when I first got my T3.  I didnt have the C6 yet, nor did I have the 300D.  This time, I imaged it with a modified camera at f/5.  The autoguider was a little unstable, and that might have been because my polar alignment might not have been perfect.  I had plenty of stars in the field.  It tracked good enough, however to do a set of 5 minute exposures at iso-800.

One thing that I've not done yet is post a single frame as taken from the camera.  This picture was converted to jpg from the raw.  I stacked 20 frames that look identical to this one to create the finished image.  I figured it would be interesting to see what a single unprocessed frame looked like in comparison to the finished product.

Here is the raw frame.

Can you see the Rosette in this image?  Its there, but it is really faint.  This is what I had to work with starting out.

Now, after stacking 20 frames, using a set of flats, darks and bias frames, and some heavy duty histogram stretching and some color balancing, this is what I finally ended up with.

Pretty crazy, huh.  As you can see, there is very little noise in this image, even in the dim areas.  There was a small amount of noise in the stack, but the software can get rid of small amounts of noise.  A single frame wouldnt have been near this detailed and smooth.

The Rosette Nebula

Well, the clouds finally broke after 2 weeks of no sunshine. Trouble is, it was quite windy, but I was able to finally get a decent image of the Rosette Nebula in Monoceros. This consists of only 7 frames at iso 800, and are 2 minute subs.

This is the best I have so far, out of about half dozen attempts. I shot 30 frames later but it was setting at that time, and this one actually shows much more detail.
