By the way, I can give you some help with polar alignment. I have been working on it for about seven years now!

Steve, that is a good image, particularly with a 60D. You got some excellent detail in the flame. Hang on to this as a benchmark. I suspect you will take a lot of images over the years of that nebula. 
 
One of the interesting things that are an ongoing challenge is the artifact about halfway up the image and about 20% from the left. There is a fuzzy globe floating there that appears to be an artifact reflection from Alnitak. I have spent a lot of time trying to figure out how to eliminate those reflective images. The last time I did the Horsehead and Flame, the artifact looked like a giant bird! There are also some interesting oddities in the actual objects you captured. For example, below the Horsehead, and toward the Flame is a star with a lot of reflective cloud around it. That is HD 37903 and is actually deep in a "cave" in the nebula cloud bank out of which it is burning its way.

Good shot Steve! I see a few objects in this image I have not noticed before and want to investigate. Hang in there; you are clearly hooked!
