My recent tarantula image took 3 nights to get all the data.
To get scope back into the same position each night I use a grid over the viewing panel of my guide star. I simply put the star into the same position and this affords me good registration.
Hope that helps and best of luck with mono imaging.

Thats interesting, I think the reverse
Lum is critical, without it your dead, its where all the detail is, so I take Lum 1st (Ha actually, Ha RGB is way better, for nebs anyway), to get started, if that doesnt work, move on
.
Once thats looking good, sneak in RGB between lum subs, and if your lum is looking really good, do RGB at the end. Always do lum if the seeing is tops on the night.
You can get away with really crap RGB with LRGB, youd be supprised how bad RGB you can get away with at a pinch with good Lum.
This assumes you have the time to do mega data, if not spread L and RGB on a 3 to one ratio, ie 3 lum, R, 3 lum, G, 3 lum, B, ....repeat untill you run out of time. That way you have something to fiddle with if it all goes pear shaped
