Oh I see, that make sense now. Great news, that'll be the perfect timelapse tool! By the way I tried the intervallometer yesterday to do day to night transition, but I wanted the stars to be there after so ETTR was not possible. With a shutter ramping, the only thing that went wrong was during the transition flicker appeared, because as the light was getting lower and lower, the camera would do 3 x 2s shots, then 3x2.5s, soflicker was visible. But your module was working freakin' great! Just need the longer exposure in ML menu now :p
