Just recently had a go at this. Although still a beginner shot by definition, I felt that, especially considering the image scale, I might receive more criticism here that I could put to use.
Telescope: AZT-14 (480mm aperture, fl=7700mm)
mount: who knows what it's called
CCD: SXVF M25C
Stacked over a dozen 60 sec, half a dozen 100 sec and probably half a dozen 100 sec colors as well. I know more subs would help, but it's not easy getting what I have, much less more 
Unguided, no filters, cropped edges.
Software: maxim dl, photoshop cs3.
I didn't pump saturation or anything much, and as a result, it's softer than your usual M1. Any criticism would be greatly welcome, as I'm sure it's possible to process way more out of this image than I got.

Updated: got a bit more nebulosity out of it. I think it's an improvement:

that's a nice start
the filament detail looks nice
-needless to say, a boatload more exposure will help
i'd suggest 1-2 hours total, at a minimum, even if you're using short subs, as long as they're not clipped.
-it will tolerate a bit more stretching
but then the dust donuts start to creep out
so i'd strongly suggest that you start using flats and (darks or bias)
-that's an impressive focal length, might consider a focal reducer.

I'm having problems on the boatload more exposure part due to mount mechanics at the moment (need to construct a stabler power source), so I'm working with what I've got here.
And yep, no flats due to no conditions to take proper flats that night. Might be able to sneak in a few later?
Anything I can do with the processing, or have I sort of wrung out everything that I can?
And thanks for the response  I wasn't sure I'd find as many people there that have to deal with this image scale, so I hope it's not too awful for this section.

how about an old pc power supply unit? I use one I found by the road, very stable 12V and 3V supply.

I'm not sure if any of those would give me the power I need. It's 60s soviet tech, so it'll be a long project before this thing starts doing exposures longer than maybe 100 seconds.
Thanks for the suggestion though, I'll see if it helps. I'm not sure it'd be enough though, considering that the mount is something over two tons, so it might need more oomph.

I think flat frames would give you the biggest 'bang for your buck' at this point.
If you know the angle the camera was attached, you could take some flat frames now. Otherwise you'll have to live with the donuts or photoshop them out. Flat frames would help you detect the outer reaches of the nebula (it does extend a bit further out). Very nice resolution - you're really zoomed in there. Looking forward to more.
For future exposures, a focal reducer would quicken your exposures and make tracking less critical. I sure would like to see pics of the 60's soviet tech setup you have.
