Thanks for replying. Nice shots too!
I've taken lots of single shots like those before over the years, including the attached from the same location; I'm keen to try something else, for two reasons. One, because the amount of dynamic depth you get from stacking is vastly improved over a single frame - as you can see comparing the two; and two, because though the seeing is fairly good where I live, it's not, like, crazily good like out in the country. Though my camera is a pro level one, I don't like shooting at ISO 6400 if I can avoid it.
As you suggest, I'm going to try a compromise between the two. I'll still use the mount but with much shorter exposures like 30 seconds, and maybe only a dozen or so. If they're that short I'll also be able to take an in-between angle so the distortion isn't so hard to deal with when stitching them together. It'll still take some fiddling but shouldn't be as much.
Also going to use a much nicer 24mm f/2.8 lens. Not as wide but the results should be a fair bit easier to work with. The distortion and vignetting of my wide is pretty extreme.
