When i try to stack images from my planetary camera (i know it is not ment to be used for dso but hey its fun) dss is unable to find any stars becouse the unstreched image is so dark. They are 5s subs at gain 101 . Once i strech the single sub i can see at least 20stars (yes i am in focus and i have my star threshold on minimum possible)
