It does not have to be that way
Program your iimage acquisistion and then you can do, say, 10 mins L (not many use subs londer than that) and then 5 mins each of RGB binned 2x2. If you think it will be cloudy do LRGBLRGB etc rather than LLLRRRGGGBBB and you will have useable data after one 25 minute cycle. This assumes you have a parfocal system (reflector and filters) OR you have automated focus. Personally I fond mono with manual focus and FW to be a pita. You can get more sophisticated of course - eg collect yout B and L data with your objective is highest (close to transit) to maximise resolution (minimise seeing effects).
Mono is really the only choice for NB imaging and photometry.
