Is a cooled camera required for short exposure imaging

To answer your question above, I don’t set any delay between subs. The only delay will be the time it takes for one sub to download to NINA and the next sub exposure starting. It’s less than a handful of seconds hence my comment about the temperature remaining steady across a session save for any ambient variations as the night progresses. 
 

I just hit start and let it run.
