As this is perhaps the most famous of all deep sky objects, I'll leave it to those who are interested to check out the Info on this object at the link above.
Image
11x1.5 minutes + 11x2.0 minutes for a total of 38.5 minutes at ISO 800
Stacked in DeepSkyStacker, Dark Subtracted
Processed in Adobe Photoshop CS3 Extended
Taken on November 8, 2010 at the Louisville Astronomical Society Observatory, in Curby, Indiana
Equipment:
Hutech Canon T1i DSLR
200 mm f5 Konus Newtonian with a Baader coma corrector and a UV/IR cut filter
Losmandy G11 Gemini GOTO mount on Heavy Duty Tripod
Orion Shorty Autoguide Scope with Starshooter autoguider
Comments: I had some trouble with the autoguider due to unstable seeing conditions, and so the guiding on this image is less than desirable. Despite the seeing problems, this is my best image to date of this object, but I am going to try later in the year, or early next year to go really deep and get some very long exposure time on it.
Enjoy,
OGM

"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!
