After looking at the data from IC 5146 that I took this weekend and comparing it to data I collected last year, I decided to do a little experiment. I combined all the data I had for this object using Deepskystacker to try to get the most bang for the buck, so to speak. I ended up with an image with a combined exposure of 1 hour and 36 minutes. This is my first attempt to combine data on the same object from two different sessions (something many more professional "amateurs" do often). Here is the result:

The stars came out very nice, as did the nebula, although I had expected to see more of the smokey part of the nebula that rings the red part. Still, more of it is visible than either original shows. All and all, I think this is my best effort to date. Considering that our observatory location has average seeing compared to many top observatory locations, I don't think it is too bad.
Note to moderators: If this image is too large, feel free to adjust the size. I wasn't sure how to do it in your forum, and photobucket hiccupped everytime I tried to do it there.

"In short, Meyer has shown that his first disastrous book was not a fluke: he is capable of going into any field in which he has no training or research experience and botching it just as badly as he did molecular biology. As I've written before, if you are a complete amateur and don't understand a subject, don't demonstrate the Dunning-Kruger effect by writing a book about it and proving your ignorance to everyone else!
