thank you again for replying.
no change if i alter gain or offset.
i should have explained the screenshots i took.
the first one is 2 hours worth of images  on ngc 1449 stacked in dss. eventually. dss has a hard time stacking as there is so few stars in images. the histogram is stuck to the left and i cant process any data from stacked image.
second, third and fourth image are just my settings in stellarmate.
the last image is from altair capture. i brought scope and camera (my setup is in loft which is why i use rasberry pi with stellarmate) to my pc took an image during day and the image looks as it should. but same image in stellarmate is just dark. histogram stuck to the left.
i have tried to copy settings as best i could from altair capture into stellarmatewith no luck.
thank you again
