Hi Rex. I like this area too. It's a challenge. There is a lot of detail to be strained out. However, I have found that the expansive reflection nebula and dust fields tend to show up acquisition issues too readily. Particularly, if images are not adequately offset one from the other.
I found this very useful in my attempts at Rho Oph - Berry and Burnell in their Handbook of Astronomical Image Processing recommend spacing images by 10 or 12 pixels - dithering. This is not the super accurate dither technique used by high end/scientific gear, just a crude but very effective way of avoiding multiplying the effects of artifacts across the sensor - reducing noise, increasing SNR, improving flat fielding, sub pixel sampling and so on.
Not all gear is set up to dither - it can be as basic as pausing guiding/tracking for a few seconds between images.
