As a photographer unless I am sending proofs to a magazine I rarely use low resolution, when shooting sports I always use 36Mp, therefore I was wondering

I have so far only used either my D810 or D4s for imaging, why do dedicated cameras such as the ASI 178MM which IF we EVER get any Sun, I will use for Ha, in programs such as sharpcap offer maximum down to 320x240

Not talking sensor size here just image size


Thanks
