Clear Skies (comma in the right spot I think but is still reads wrong)

On saturation: Agree that it is enhanced but I beg to differ that it is overly so. I tried to bring out the H-alpha regions a bit. If you look at M81 it is not uncommon to see those colors. I was surprised that M82 came out the way it did, but I like it. To each his own.

Ajay sorry ,I read my post back I was wanting to say yours was not oversaturated not the other way around sorry missed a comma,,, ....
No problems Carl. Its all good. In the field of pretty picture making some subjectivity is bound to exist. So I did not take it poorly. Thanks for the clarification.

really nice - and just 2 hours? wow.
Skies were nice and dark. Here's some info about the site: http://www.tmspa.com.../site_info.html
Last summer a wildfire swept through here as large parts of central WA burned.
Back on the subject, its the dark skies combined with Pixinsight magic (HDR multiscale) which you know all about:)

Many people (here and on Flickr) have commented on the amount of detail I was able to get with 2 hrs with a canon 350D at 800 ISO.
To tell the truth my first effort was not so great.
This image was acquired in my second season in 2010. However I did collect flats, flat darks to correct the flats and darks. I don't use bias frames because I do traditional dark subtraction and dark frames already contain the bias signal. Proper calibration helped stretch the data more. I also had nice dark skies and the seeing was better than average for most part.
