As for the processing, Pixinsight has some really good tools such as mozaic by coordinates for registering the files and Gradient merge mosaic for integrating them. I use both these tools quite often and work really well. Hope you go ahead with it, sounds like an amazing project.
I've just put in a 30º FOV around M8 to see if SGP can handle such a large region. It was something that I had considered attempting but didn't think it would be able to handle. It did! It has gathered nearly 50 panels and stitched them together for me
Apparently it would take 172 panels to do 30º around M8. This would be at 2.77"/pixel with 15% overlap and full colour. Thanks for making me test it Rex

Where my main questions stems from is whether I should be doing some basic processing on each individual image and then stitching them OR stitching them and then doing basic processing. Considering that my current plan is just single 120s exposures out of an unmodified DSLR, it is going to be noisy as all getup. Processing is not going to be anything fancy as the data just isn't going to take it.

FYI, doing the aforementioned would end up with a 1.75 gigapixel image
