As you can see on our Widefield Setup, the camera is mounted on a tracking mount so I was able to take a number of different exposures ranging from 10 seconds to 4 minutes. This enables you to retain the core of the trapezium in the nebula which becomes blown out on the long exposures.
They were stacked in Deep Skystacker and then layered in Photoshop.
If you are trying just a single shot. A single 4 minute exposure will bring out the nebula but as explained the core will be over exposed.

any chance you could let me know what your exposure time was?
The Canon body used for this shot was an unmodified 40D.
This shot was with the focus stop at infinity.

I see that you mounted the Nikkor on a astro-modified (I'm assuming) Canon body. Did the focus stop at infinity work with this lens and body combination? Just curious, cause I'm itching to try the same thing with my lens.
Gorgeous shot! I am constantly amazed at what is out in space. I have a cousin who is a retired astronaut and flew on 3 shuttle missions. I do wish he lived closer as I would love to discuss deep space with him!
