Re: Best DSLR or ILC for Night Sky Imaging?

as i stack mostly and use shorter than bulb exposures i did not have a problem . but yes in bulb mode there seems to be that small stars and/or the centre of bigger stars are is washed out .

the A7S has larger pixels than the A7R : this means that a small star will be more affected with  the A7S than the A7R.
