A jednak 400 ISO przy przesłonie >4 daje odpowiedni obraz, paradoks, z biegiem miesięcy niebo ciemnieje. Wiem już czemu DSS Live znajduje tak mało gwiazd na tych klatkach, odpowiada za to zmienna: Star detection treshold. Przez ustawienie na 50% FWHM wychodzi na oko dwa razy większe niż w rzeczywistości.
