Thanks.Kaczorek
I'm not sure have i tried that option before cause
indilib.org/devices/ccds/gphoto.html
is mentioned ""Nikon is officially supported under GPhoto but the level of features supported is less than that of Canon cameras. For bulb exposures to work, you must set Capture Target to SD Card. By default it is set to Internal RAM which is problematic in Nikon cameras."
Anyway I tried also "internal RAM" option but same error occured
