This is a semi wide field of the Eagle Nebula. Image and details are at:

In doing this pic, I took Ha and full luminance data along with the RGBs. I did a lighten combine on the luminance over the Ha. (Richard Crisp can describe the issues of Ha only for Luminance.) The monochrome result for that is here (also a link on the Eagle page):

That is a great image Jim, the scope and camera seem to be an excellent match.

That's a good field of view and framing for this nebula, Jim.

Nicely resolved, and that is quite the field of view. Good stretching to bring out the dim parts. I might have to play with the Lum/Ha mix idea. I did get some lum data, but the seeing was even less than mediocre for the Four Corners.

Hey Jim ...

Beautiful image of the Eagle. Very natural looking shot with superb transitions from the bright areas to the faint. I think it's one of the nicest I've seen in a while.
