Can anyone help me with this puzzling problem, please? I’ve collected 10s subs on the the Crescent Nebula over several nights. A couple of nights ago I stacked the subs in the app and the result showed 68 minutes of data. Last night I collected about 20 minutes more data before the clouds rolled in and the live stack looked ok. However, when I stacked all the subs I now get a result showing only 54 minutes of data and over 200 subs “rejected”. It must therefore have rejected subs that it previously accepted. There hasn’t been a firmware or software update between the two stacks, so what’s happening?
