Theres another issue here as well, such as darks and flats what need is there to do these on the mount at the same time you do the lights if you can simulate the temperature etc then these can be done indoors.
Likewise DSS will stack images of different exposures and ISO settings. So Dougie if at the end of the day it improves the resulting image why not do it in my opinion but how should I know I'm just a novice.
